DESCRIPTION
How do you ensure that the code checked into version control is good? Do you run Continuous Integration on all submissions? Do you mandate that all developers run some form of validation before they submit? In this talk, hear how Xilinx leveraged Perforce to build a fully-automated system to validate everything before it hits version control, its impact on their developers, and how it changed the way they create software.

• Workspace integrity is hard
• Dependent changes
• Remote site and user support difficulties
• No true enforcement
Problems
#
• Control of Workspaces
• Isolate changes
• Leverage core infrastructure
• Be enforceable
