1 GENERAL ALTIUM DESIGNER CONCEPTS Simon Kennedy

1 General Altium Designer Concepts

Altium Designer is a powerful and complicated fully integrated PCB design suite. Altium has

in recent years tried to go beyond just implementing hardware to become more of a complete

design suite. This tutorial is going to teach the basics of using this tool to create a PCB.

1.1 Project and File Types

Altium uses project files to collect the different types of files that are used in your design.

PrjPcb is the file extension. In a project a number of other different files can be included.

The five main file types that make up a PCB project are:

• Schematic Document .SchDoc

• PCB Document .PcbDoc

• Schematic Library .SchLib

• PCB Library .PcbLib

• Output Job .OutJob

Any number of these files may be the member of a PCB Project. The example in this tutorial

will use one of each, but more complicated designs may require many more.

1.2 .SchDoc

The schematic is key to the creation of our useful PCB. Due to the error checking built into

Altium it is very difficult to produce an error that doesn’t have some relation to the schematic

so care and attention here will pay off. Schematic Symbols are inserted into our Schematic

Document which contain pins and parameters to link the symbol to it’s PCB Footprint. These

pins are connected via wires and net names to produce the net list which then generates the

connections for the PCB.

It is important that schematics are drawn in a clear and easy to understand manner.

Altium Tutorial 1 of 27

1 GENERAL ALTIUM DESIGNER CONCEPTS Simon Kennedy

1.3 .PcbDoc

The PCB file is where the physical implementation lives. Typically a two copper layer FR4

PCB is used although many more layers can and are used in industry. The PCB file is used

to generate the Gerber files which are sent to the manufacturer to make the board. There are

many layers that are present in the PCB document which each have a significance explained

later in this document.

1.4 .SchLib

The SchLib is a library of Schematic Symbols. Library creation is a time consuming but

incredibly important part of good PCB design. It is very important to check the datasheet of

each component to be used to ensure that the schematic symbol matches the device. Schematic

Libraries also contain parameters that can be used to determine where the components can be

purchased from, some key performance parameters and, if used correctly, Altium can find out

if the component is in stock and the pricing information.

1.5 .PcbLib

The PcbLib is a library of Component Footprints. Footprint creation is often difficult as the

engineer needs to determine exactly what should to be included and what size and shape the

pads should be. Different manufacturers use different names for the same footprints. Sometimes

they will use the same name for different footprints. This is why it is very important to check

the data sheet. Components have a number of pad that have a name that correspond to the pins

on the schematic symbol. Other useful information includes pin one location and component

body size. Some examples are included in the tutorial.

1.6 .OutJob

Output Jobs contains a number of output generation macros. Generation of Gerber files, NC

Drill Files, Bill of Materials (BOM), Schematics and PCB prints. This enables quick and easy

generation of files to be sent to the manufacturer.


2 CREATING A NEW PROJECT Simon Kennedy

2 Creating a New Project

To create a new PCB, project needs to be created and to this added the various files.

To create a new project File → New → Project → PCB Project

In your workspace, there will now have a empty project called PCB Project1.PrjPCB

Lets now add a schematic document File → New → Schematic

This will add a blank schematic document to the project.

It is a good idea to save as you go with Altium as the application sometimes likes to lock up

just when most inconvenient.

Projects should generally be saved in their own folder to keep path references correct. A good

place to save the documents is C:\Projects\PCB Name

Add and save a schematic library, PCB library and PCB document in much the same way.

In the case of our example project, Line Tracer, the Projects tab will look like figure 1.

Figure 1: Project Files


3 ALTIUM WORKSPACE Simon Kennedy

3 Altium Workspace

Altium uses a series of docked windows known as workspace panels around the active workspace.

These workspace panels can be opened from the View → Workspace Panels menu. The

default setup is a good place to start and often a good place to return to if a window gets closed

accidentally. To restore the Altium window to its default appearance click View → Desktop

Layout → Default. These workspace panels can float or can be docked by dragging to the

sides of the screen. Figure 2 shows the default window layout.

Figure 2: Default Altium Workspace Layout


4 LIBRARIES Simon Kennedy

4 Libraries

Whilst not the most most interesting of topics, a lot of time can be wasted if errors are present

in libraries. Altium does have quite a few built in libraries. but generally it is quicker to make

the components you want to use yourself. You also gain confidence that the symbol or footprint

is going to be correct. A PCB won’t be able to exist without library information. Most large

companies will employ a least one person to manage their libraries and keep them correct.

Seeing that there is just you, this important job falls upon your shoulders.

4.1 Schematic Library

Figure 3: An Example Schematic Symbol

Schematic Libraries are straight forward to construct. Key to producing understandable

schematics is producing meaningful and easily understood symbols. The simple creation flow

is:

• Name the Component (part number)

• Draw a Symbol

• Add pins and name or number them

• Add parameters. At a minimum you should include: Manufacturer 1, Manufacturer Part

Number 1, Supplier 1, Supplier Part Number 1, Comment, Default Designator

• Add a footprint



Figure 4: Schematic Symbol Editor

To add a new component to our library click Add on the SCH Library workspace panel as

shown in figure 4. Draw the symbol in the workspace. Using the tools in the Place menu.

In the case of an IC it is often best to draw a rectangle. Add pins to our symbol using the

Place→ Pin tool. Altium has the ability to use keyboard short cuts in a lot of places which

can help speed up a lot of tasks. In this case P then P is the same as Place Pin. Click to

place on the schematic and use the Spacebar to rotate.

To change the parameters of the pin right click on the pin and select Properties. The Pin

Properties window will be displayed as in 5. A short cut to display this window is pressing

Tab before placing the pin. The Display Name needs to be changed to what the pin will be

called or what it does. Sometime this might get in the way of a clear symbol and it can be

hidden by clicking on Visible. Also change the Designator to match the pin name on the

footprint. Generally this will just be a number. The other parameter that is useful is Length

which changes the length of the pin.

To add parameters to the schematic symbol, click to select on the component name in the View

→ Workspace → SCH → SCH Library workspace panel and select Edit. The Library

Component Properties window will appear as in figure 6. Default Designator should be changed

to for a resistor for example: R?. The ? means a yet to be defined designator number. The

component should have a reasonable Comment, Description (Digi-Key component pages are

a good source) and Symbol Reference, a good system is the part name and package name.

Supplier connection should be set up with the Parameters.



Figure 5: Editing Schematic Symbol Pin Parameters

Figure 6: Editing Schematic Symbol Using Library Component Properties

In the example of our MBR230 diode the parameters are set as shown:

• Manufacturer 1 = ON Semiconductor



• Manufacturer Part Number 1 = MBR230LSFT1G

• Supplier 1 = Digi-Key

• Supplier Part Number 1 =MBR230LSFT1GOSCT-ND

Examples are included the Line Tracer Project or in the Tutorial.

4.2 PCB Library

Figure 7: An Example Footprint

PCB Libraries and footprint creation can be challenging. Referring to the data sheet for the

component is essential for creating an effective footprint. The simple creation flow is:

• Name the footprint (e.g. 0805)

• Draw the pads and position correctly

• Add extra information on the other layers. There should at least be something Silkscreen

and 3D mechanical layer.

An example layer usage:

• Top Layer (Copper Land Pads)

• Top Overlay (Text and Orientation Information)

• Top Soldermask (Location of removal of soldermask)



• Mechanical 4 - Assembly Drawing (.Designator and .Comment)

• Mechanical 13 - 3D Body (Component Outline and 3D Body)

• Mechanical 15 - SMD Outline (Minimum Clearance between Components also known as

Component Courtyard)

Figure 8: Footprint Editor

To add a new component to our library click Add on the PCB Library workspace panel as

shown in figure 8. Key to footprints are the pads. To place Pad select the Place → Pad or P

then P tool. Before placing these in the workspace press Tab to enter the Pad window. The

dimensions and shape are defined here as well as the designator. Click place the component

and set its location on the grid.

The PCBLIB Inspector workspace panel is very useful for aligning pins around the origin.

This tools being is shown in figure 9. The Inspector workspace panels are powerful a way to

make changes to all of the selected items and can save a lot of time and clicking.

Select between layers using the tabs at the bottom of the PCB Library editor window. To add

lines to the Top Overlay, select the Top Overlay tab at the bottom and then place a line using

the Place → Line or P then L. Do this for any other layers that you want to add features

to. To change layers using the keyboard use + and - on the number pad to scroll between all

layers and use * on the number pad to scroll between copper layers.

4.3 Add a Footprint to Schematic Symbol

The newly created footprint needs to be associated with the schematic symbols in the schematic

library window. Go back to the schematic library window and click the Add Footprint button

circled in figure 4. Browse and select the correct footprint. This window is shown in figure 10.



Figure 9: PCBLIB Inspector Workspace Panel

4.4 Update Open Documents with Changes Made

If a schematic symbol or PCB footprint is changed between our initial placement and release

then the easiest way to update the document is to right click on the changed symbol or footprint

and click Update Schematic Sheet or Update PCB with .... Be aware that this tool will

update all devices in the schematic with the same Symbol Reference. Be aware that if there

have been any changes to parameters in schematic editor these will all be lost i.e. component

value. This is why it is best to have a separate item for each value and size of component as

in the Line Tracer library and the Tutorial. Also, these tools will only update elements that

appear in currently open documents so make sure that all of the sheets of schematic or PCBs

that use the device are open before clicking update.


5 SCHEMATIC Simon Kennedy

Figure 10: Adding a Footprint

5 Schematic

Drawing a schematic in Altium is extremely straight forward. The process flow here is:

• Place Components

• Draw Wires between Components

• Place Net Labels and Power Ports

• Annotate Schematic

• Compile Project to Check for Errors

5.1 Place Components and Connect

To place components in the schematic document click Place → Part or P then P. Browse

the library and select the component that you want to place. Click a location on the schematic

to drop the part in that location. To rotate the component use the Spacebar and mirror in

the x plane using X and in the y plane using Y. To continue to place the same component click

again. To exit this mode use the Esc key.



Figure 11: Example Schematic

5.2 Draw Wires

Once the required components have been placed connect the pins on the schematic using the

wire tool Place → Wire or P then W. Click and draw the wires that are needed by clicking

onto the schematic sheet.

5.3 Net Labels

To produce a neater schematic net labels can be used to connect various pins and wires together.

Place these using the Place → Net Label tool or P then N. Press Tab or if already placed

Right Click to bring up the Net Label box as shown in figure 12 and change the Net name.

Also very useful are power ports which can be used to signify VCC and GND. Use this tool via

Place → Power Port or P then O. Press Tab to bring up the Power Port box as shown in

figure 13 and change the Net name.



Figure 12: Net Label Box

5.4 Text Annotations

If text annotations are required then these can be placed via the Place → Text String or P

then T. Press Tab to bring up the Annotation box as shown in figure 14 and change the text.



Figure 13: Power Port Box

5.5 Compile for Errors

To ensure that all nets are connected it is important to use the No ERC directive to ensure

that errors are not reported when not needed. Place these using Place → Directive → No

ERC or P then V then N.



Figure 14: Annotate Schematics with Text

5.6 Update Designators

To update the component designators automatically, use the Annotate Schematic tool. This

is located in Tools → Annotate Schematic. To update all of the designators click Update

Changes List then click Accept Changes (Create ECO) then click Execute Changes.

This is shown in figure 15.

To compile the schematic to check for errors click Project → Compile Project .... If any

errors or warnings are present these will appear in the Messages workspace panel. Don’t

ignore these errors or warnings otherwise it is very likely issues will arise during layout or

testing.

Finally the time comes to begin designing our PCB. This step has been made much easier

due to the hard work that has been done so far. At this point the footprints should match

the component package physical dimensions and the schematic should connect the correct pins

together. PCB layout can be broken down into the following steps:

• Add the Components to the PCB document

• Define Board Shape and begin to Floorplan

• Group Components and begin placement

• Track nets, starting with the highest priority and working down.

• Add Polygon Pours

• Complete Layout and Tracking

• Add and Organise Designators and other Silk Screen Text

• Run Design Rule Check


6 PCB Simon Kennedy

Figure 16: Example PCB Layout

6.1 Transfer Design from Schematic

First the netlist and footprints need to be transferred from the schematic editor into the PCB

document. To do this click Design → Update PCB ... An Engineering Change Order

(ECO) window will appear and click Execute Changes. Ensure to note if any errors occur.

Most commonly these will involve missing footprints from the PCB library. Resolve these errors

and repeat the process again.

6.2 Define Board Shape

In the PCB document now the board will appear as the default size with all of the component

footprints located to the side of the PCB as in 18

The Board Outline should be defined. Most simply, this is done by drawing a series of lines

on Mechanical 1 layer. Select this layer at the bottom of the screen and draw the tracks to

produce an area of the desired dimensions. Place outline lines by using the Place → Track

or P then T. After placing these lines, select them all by clicking each whist holding Shift.

Define the Board Outline by using Design → Board Shape → Define from selected

objects. The area within this outline will now appear black and the outline has been defined.


6 PCB Simon Kennedy

Figure 17: Engineering Change Order

Figure 18: Newly Imported PCB Document

Alternative methods exist such as importing a .dxf CAD file but these are not covered here.

6.3 Group Components

Referring to the schematic to determine functional groups and begin to organise components

into functional groups. Select components by clicking and the are able to be moved by clicking

and dragging the component to the desired location. Components can be rotated by using

Space. Groups of components can be moved by selecting a larger number of components,

either by clicking and dragging a box around them or by clicking on multiple components

whilst holding down Shift. Once these functional groups have been put together arrange the

components to untangle the web of unrouted nets displayed by the white lines. Move these

organised functional groups to their desired location of the board.


6 PCB Simon Kennedy

Figure 19: PCB with Defined Board Outline and Grouped Components

6.4 Tracking

Track in order of priority. Start with nets such as USB or other high speed signals, analog high

impedance nets, high current nets such as a battery input, crystals and decoupling capacitors.

Tracks can be placed by Design → Interactive Routing or P then T. Snapping is a useful

way of getting tracks to connect to the centre of pads. Ensure this is turned on by checking

boxes in Design → Board Options or D then O. Ensure that Snap on all Layers and

Snap to Board Outline are selected. Select the track tool then click on the centre of a pads

and drag the mouse to draw the track. To enforce a location click and the track will be locked

to that location. Continue to draw the track until it is completed. Tracks can be moved by

clicking and using the grab points.

Vias are placed to change layers. They are plated drill holes that are conductive. Boards almost

always need more than one layer to successfully route all of the nets. To place a Via Design

→ Via or D then V.

As with almost everything in Altium, pressing Tab before placing the via or track can change

the options. This can also be achieved via the PCB Inspector workspace panel or by right

clicking on the object and selecting properties.

To move into and out of single layer display mode use Shift + S. This enables the user to


6 PCB Simon Kennedy

see just the current layer. Holding Ctrl and clicking will highlight all copper connected to

the clicked net. Exiting can be done by Ctrl clicking outside the board. Components can be

located on the top and bottom sides. They can be moved between the layers by right clicking

and selecting Properties and changing the content of Component Properties → Layer.

6.5 Polygon Pours

Polygon Pours are planes of copper that can be used as a low impedance way to connect ground

or any other signal but generally are used for power nets.

Two methods for defining the area of the polygon pour are:

• Creating a series of tracks around the boundaries of the desired pour boarder then using

the snapping to make the edges neat. Place polygon pours using Place → Polygon

Pour or P then G

• Selecting the board outline or already existing complete shape of tracks and using Tools

→ Polygon Pours → Define from selected objects

The Polygon Pour properties window includes some important options:

• Fill Mode should be set to Solid

• Name should be Layer - Net

• Layer should be the desired Layer

• Connect to Net - Desired Net

• Select Pour over All Net Objects

• Select Remove Dead Copper i.e. areas of copper not connected to the desired net

Polygon pours can be re-poured when other tracks are changed or components moved. This is

done via the Tools → Polygon Pours → Polygon Manager. The Polygon Manager also

sets the priority or order with which polygon pours are poured so that pours outline areas may

overlap but pours don’t.


6 PCB Simon Kennedy

6.6 Designators and other useful Silk Screen

Designator text is located on the Silk Screen. These are by default quite large and should be

reduced in size to make it simpler to located them on the board. Silk Screen text should also

contain the board name and any other useful information such as pin out of connectors. These

can be placed by Place → String or P then S. This will place the string on the currently

selected layer. Be careful what layer this is placed on.

6.7 Design Rule Check

Design rules can be pretty annoying. They are however essential to ensure that the PCB

functions as designed. Key to this is ensuring that the selected design rules are realistic.

Figure 20 shows some typical design rules from a cheaper manufacturer.

Rules need to be set in Altium for the checker to compare with. They can be set in Design →Rules. Check that these rules matches the PCB manufacturer or have bigger clearances and

widths.

Online DRC runs by default highlighting violations green. To run the full Design Rule Check

click Tools → Design Rule Check. Click Run Design Rule Check. Review the output

report and fix the errors. Only once all of these errors are fixed should the PCB be released.


7 GENERATING OUTPUTS Simon Kennedy

Figure 20: Design Rules from ITead

7 Generating Outputs

Altium files are not a very good way of transferring manufacturing data to the manufacturer

therefore documents in industry standard formats should be generated from these files to release.

Typically released files:

• Schematic Drawing in PDF format (Released to the Engineers working on Project)

• PCB Assembly Drawing in PDF format (Released to Assembler and Engineers on Project)

• Bill of Materials (BOM) (Released to Assembler and Engineers on Project)

• Gerber Files (Released to PCB Manufacturer)

• NC Drill File (Released to PCB Manufacturer)



Figure 21: Completed Output Job

• Placement File (Released to Assembler)

• Solder Paste Gerber File (Released to Assembler)

For the purposes of simple projects schematics, BOM, Gerbers and NC Drill files are needed.

To simplify this process Altium includes an Output Job .OutJob file which includes settings

to generates these with one click.

7.1 Schematic

To output the schematic to a PDF:

• Click Add New Documentation Output → Schematic Prints → [Project Phys-

ical Documents]

• Check the box at the right of the line Enable

• Right Click on the Schematic Prints line and configure the Page Setup for A3 and Colour

• Click on the PDF Button on the right to export



7.2 Gerbers

To output the PCB to Gerber Files:

• Click Add New Fabrication Output → Gerber Files → PCB Name


• Right Click on the Gerber Files line and click Configure

• Select each of the used layers in the second tab Layers

• Select Plot all used layer pairs twice in Drill Drawing tab

• Click Ok

• Export the Gerbers by clicking on the Folder Structure Generation Button on the right

Generally it is best to use what every units you worked in, i.e. mm or mil. The format 2:3,

2:4 and 2:5 corresponds to the resolution of the Gerbers. It is generally best to use the highest

resolution that is possible (2:5) unless the manufacturer complains. Ensure to open Gerbers

and review each layer to ensure they have been output correctly. It is very common to have

designators or other erroneous information on the wrong layer. The free Gerbv viewer is quite

easy to use if the Altium one seems too complicated to use.

7.3 NC Drill File

To output the PCB to NC Drill Files:

• Click Add New Fabrication Output → NC Drill Files → PCB Name


• The default configuration is suitable

• Export the NC Drill Drawing by clicking on the Folder Structure Generation Button on

the right



7.4 BOM

To output the Bill of Materials:

• Click Add New Report Output → Bill of Materials → [Project]


• Right Click on the Bill of Materials line and click Configure

• Add the desired columns and order by dragging

• Export the Bill of Materials by clicking on the Folder Structure Generation Button on

the right


8 TUTORIAL Simon Kennedy

8 Tutorial

The tutorial involves producing PCB with a non-inverting Operational Amplifier and two volt-

age regulators. The following tutorial should help the user learn how to use Altium effectively

and independently.

The project files have been included for your use. The task is to complete this design

8.1 Schematic Library

An almost complete schematic library has been included for your use. It contains everything

but the positive adjustable voltage regulator that we will use. The schematic symbol for the

LM317EMPX/NOPBCT need to be produced. This part has three legs and a tab. Check the

data sheet to find out what to connect this tab to. The footprint has four pins numbered 1-4

with 4 assigned to that tab. Tasks:

• Get the datasheet from www.digikey.com

• Create the Symbol and Pins

• Complete the parameters

• Add the correct footprint to the symbol (SOT-223-4)

8.2 PCB Library

An almost complete PCB library has been included for your use. It contains everything except

for the footprint for the AD8661ARZ-REEL7 operational amplifier that we will use.

Tasks:

• Get the data sheet from www.digi-key.com

• Create the footprint with all four pins.

• Add Silk Screen and Component Body

• Add this footprint to the AD8661ARZ-REEL7 schematic object.
