描述

2.1i TRCE shows several paths that are failing timing constraints. Investigation

shows that the failing paths are not being included in the correct timing constraints.

The failing paths show up in the period specification when they should show up in

another from GRP_CHIP to GRP_CHIP constraint (TS_Chip_rate1).

This problem is due to an overflow of an internal table, which consequently

causes identical paths from the period and exception timespec to appear different.

解决方案

A fix for this problem is included in the 2.1i Service Pack 1 Update which is

scheduled to become available on September 1.
