Background to metamodeling
Industry examples and experiences
Generating code and beyond
Summary
Metamodel and model: instance of
Concepts Symbols
Generators Rules 1 2 3 4
1. Enter concepts &
their properties 3. Draw or import the symbols
2. Pick rules from templates
4. Specify generators
Language = concepts+rules+notation
Example: Breakfast - a modeling tool for SystemC
Easy to create virtual platform model
Using QEMU for CPU models
Easy to connect QEMU to SystemC models
Easy to connect interrupt signals to CPU
No need of deep knowledge about SystemC TLM2.0
Abstraction is LT(Loosely Timed)
Easy to create SystemC code for high-level synthesis
Pin level interface between modules is generated automatically
SystemC code for line buffer for image processing is generated
Designers can concentrate coding for algorithm
SystemC model for high-level synthesis can be used on a virtual platform
No clock on a virtual platform
Virtual platform uses the same SystemC code for a register I/F(address
decoder) as high-level synthesis

Experiences from practice
"5-fold productivity increase when compared to standard development methods"
"The quality of the generated code is clearly better, simply because the modeling language rules out errors"
"An increase of at least 750% in productivity, and greatly improved quality in the code and development process"

Comparing to earlier practice
(typically compared to coding)
Generation of non-software artifacts
Single source, multiple targets:
- Automated build automating compile and execution
- Checking completeness and uniformity
- Simulation data
- User guides, installation guidelines
- Configuration
- Metrics
- Testing and analysis
- Material usage
- Documentation
- Review reports
Case of Fishing Farm automation system,
Preschern, C., et al 2012
Modeling both SW and system
Combining two or more languages via metamodeling
Metamodel covers integration rules for
– Correctness
– Consistency
– Completeness
Hardware and software co-design
Integrating various views with a common metamodel
– e.g Y-model
Main challenge is organizational
– Changes status quo
Design space exploration
Performance analysis, error analysis, fault tolerance etc.
– Integrate with tools like ABSOLUT, SPIN, UPPAAL, etc.
– Annotate results back to models
Automating testing
Modeling test cases/test logic and generating test data
Time to develop languages & generators
63 language concepts
XML generator
60 language concepts
C, HTML, build script generators
36 language concepts
Assembler generator
77 language concepts
Python generator
Java generator for
simulation
143 language concepts
J2EE generator Man days
