1.5i Ngdanno - Timing simulation for ROMs is overly conservative

Description

Keywords: ngdanno, time_sim, sdf, rom, timing simulation

Urgency: High

Description: Ngdanno is not applying the correct delays to the ROM primitive. It is only adding the output delay and not the net delay on the source nets. This results in the timing simulation delays to be to conservative.

Solution

A fix for this problem is included in the 1.5i Service Pack 1. For details
