TIMING ANALYZER 6.0.1: Discrepancy between Timing Analyzer and Xdelay

描述


Urgency: Low



General Description: By default, Xdelay and Timing Analyzer trace different paths for maximum delays.

解决方案


Timing Analyzer and XDELAY have different default settings.

XDELAY includes Asynchornous set and reset paths, while Timing

Analyzer does not. To turn this on in the Timing Analyzer, select:



PATH FILTERS->COMMON FILTERS->CONTROL POSSIBLE FALSE PATHS

SELECT 'SET/RESET to Q PIN OF FLIP-FLOPS'

MOVE all signals to INCLUDED BLOCKS.



Timing Analyzer should now trace the same paths as XDELAY and report

the same maximum delays.
