simulation of DCM blocks
Hi all,
I am designing a hadware which use clk and 2xclk. I am planning to
use DCm block in the V4 to get the 2x clock. But the board is not yet
available. So i thought to proceed with the post PAR test. Synthesized
the a DCM block in which clk0 is fedback to clkfb through a bufg.
generated post par simulation model using ISE 7.1. And simulated it on
model sim with libraries X_DCM_ADV.v etc attached. But the clk0 and
clk2x gives a flat '1' output not clock. Why is this behaviour. Is it
possible to simulate the DCM behaviour ??
