Towards Robust False Path Analysis


Existing false path detection techniques such as floating mode analysis have explicit dependency on gate delay assignments, i.e. if gate delays increase as the result of gate sizing, the false path information is invalidated and needs to be recomputed from scratch. I will show that false path detection can be done independent of gate delay assignments without losing accuracy. The core technique used is a generalization of false-path-aware required time analysis I proposed earlier. Saldanha has recently addressed the same problem with a different approach. I will contrast my work with his.
