Goals of Design Data Management
• Collaborate with team members and share design
data regardless of geographical location & time
zone
• Manage all design data from Docs to GDSII
• Control and audit access and actions
• Track changes and maintain revisions and releases
• Streamline design flow
• Tapeout accurately with confidence

Issues with Ad-Hoc Processes
• Design errors
– Require very expensive re-spin
• Project delays
– Impact time to market
• Lack of control and visibility
– Decreased predictability
• CAD support nightmare

Challenges of Managing Design Data
• Design tools often create several files with program
generated names
– Examples: Schematic & Custom Layout editors
• Data for each design unit may be saved in several files
• Several temporary & run files are also created by the tools
– Example: log, lock, backup
• End users cannot easily make sense of the design data
– Which files should be managed & versioned
– Which files belong together
– Which files should NOT be managed
• Design operations affect DM
– Open for edit, rename, copy, etc.

Universal DM Adaptor
• Configurable rules to recognize and organize design data
– Recognize design libraries
– Recognize design objects
– Organize required design files into composite design objects
– Exclude temporary files
– Re-apply rules on check-in to recreate composite design object
• Soft integration with design tools
