Timing Analyzer 3.1i - Timing Analyzer does not report label (-Th) for a hold violation

Description

General Description:

Timing Analyzer does not report label (-Th) for a hold violation, making it inconsistent with TRCE:

TRCE: CLB_R39C2.S1.CLK....................Tcki........(-Th).....-0.766

Timing Analyzer: CLB_R39C2.S1.CLK.....Tcki....................-0.766F

Solution

Use TRCE from the command line to obtain the correct results.

This problem was reproduced using D.25. In the XML file that Timing Analyzer uses to generate the report, this delay is correctly tagged with the twHoldTime="TRUE" attribute.

NOTE: To get the path with the Tcki delay in the report, use the skew check option.

This problem was approved by the RCB to be fixed in D Service Pack 8.
