5.1isp2 Timing Analyzer/Trace(TRCE) - A negative Tdcmino value causes hold errors in timing for the PSDONE path

描述

General Description:

A hold error appears in my timing report on the PSDONE path from the DCM to a register.

解决方案

This error occurs because the PSDONE path is associated with the wrong timing parameter (Tdcmino). You can work around this problem by applying a TIG constraint on the net from PSDONE to the register.

This problem is fixed in the latest 5.1i Service Pack, available at:

The first service pack containing the fix is 5.1i Service Pack 3.
