Problem Title:
V2.1, V1.5i COREGEN, FOUNDATION: Virtex block RAM generated by CORE Generator does not
simulate initial values properly in Foundation functional simulation
Problem Description:
Urgency: Standard
General Description: When Coregen is used to create block RAM and is
initialized using a .COE file, the RAM does not initialize properly in Foundation
functional simulation. Zeros appear on the output of the block ram,
regardless of the inital values set in the .COE file.
Solution 1:
A workaround is to run the design through Translate in the Design Manager,
then run a Checkpoint Gate level Simulation from the Foundation Project
Manager (Tools --> Simulation/Verification --> Checkpoint Gate Simulation
Control). This will include the initial values taken from the .COE file, and
properly simulate the design in the Foundation Simulator.
