TRCE/Timing Analyzer 2.1i: Clock DLLs with period constraints appear in the reports as if they are not constrained

Description

Keywords: DLL, CLKDLL, period, constraint

Urgency: Standard

General Description:
Period constraints on clock DLLs get pushed to the appropriate clock output port
on the DLL. 'Report Paths not Covered by Timing Constraints' report in Timing
Analyzer now reports the DLL as not being constrained. The DLL is in fact
constrained, but the actual constraint gets pushed through the DLL, so Timing
Analyzer thinks that the DLL is not constrained.

解决方案

Solution:

Ignore the paths covered by 'constrained' DLLs.
