AR# 3938
F1.4, F1.5, Timing Simulator: '-' in signal names converted to '_'
Description
Keywords: Foundation, ngd2edif, simulation, -, _,
Urgency: Standard
General Description: When a design contains a dash as the last character in a signal name ('-'), the dash is converted to an underscore by ngd2edif when doing a backannotate (timing sim).
In timing simulation, this will cause test vectors created in Functional simulation to appear blank (or missing signals), as well as problems with command files in simulation, that refer to specific signal names, due to the fact that the names have been changed from containing '-' to containing '_'.
This renaming can be seen in the time_sim.edn file.
解决方案
Workaround: Remove any dashes ('-') from the end of names in the design, or replace them with '_'.
