摘要：
In the course of unit timing, there exists the possibility for a non-compute (N/C) on a particular net in an IC chip design, which could be caused by numerous things, including but not limited to a pin being tied to power, a floating output, or invalid timing test for a given phase at a test point. A process automatically verifies that all non-computes are understood and exist for valid reasons, in order to ensure all necessary paths are being timed. The process takes a conventional Comprehensive Report output of a unit timing run and generates macro specific N/C reports for designers to review and sign off on.
