Description
Keywords: timing report, .tim file, .Q
Urgency: standard
General Description:
The detailed timing report assigns .Q extensions to some signals. The signals with .Q extension are usually register functions. This can cause some confusion when reading the report.
解决方案
Check if a clock net is associated with the signal having .Q extension. If that is not the case, then the signal under consideration is not a registered signal.
