Description

Why are my constraints not been analyzed? 

 

In 11.1, there are known issues with the TIMEGRP PADS constraints. An example constraint follows: 

TIMEGRP "grp_name" = PADS "instance_name"; 

 

The tool is failing to include all constraints during analysis.

Solution

To work around this issue, create the constraints as follows: 

INST "instance_name" TNM = PADS grp_name; 

 

This issue is scheduled to be fixed in the next quarterly release.
