Creating and ensuring correct and consistent constraints, at all levels of the design hierarchy and throughout the design cycle, is a vital and increasingly challenging task. The difficulties can include: writing new constraints, managing thousands of lines of legacy constraints, managing thousands of timing exceptions, experiencing unwanted iterations due to changing constraints and implementing erroneous constraints resulting in redesigns or even respins.
The SpyGlass Constraints solution provides a productivity boost to IC design efforts by automating the creation and validation of constraints. SpyGlass Constraints generates new constraints where needed and verifies that existing constraints are correct and consistent early in the design flow.
The SpyGlass solution can trim weeks or more from design schedules by pinpointing the root cause of constraint problems. By ensuring valid constraints, SpyGlass Constraints can eliminate design flaws and costly respins. The solution also creates a smooth handoff between tools in multi-vendor flows. Advanced options streamline constraints management tasks by automating timing exception generation and verification.
