I am doing some functional post-synthesis simulation on Modelsim and I can see lots of zero width glitches in the VCD file. Considering that it is a functional simulation, it seems to be odd.
I was using Nangate standard cell library and there was a problem in this library. In fact there was some sort of feedback in some cells and modelsim does lots of iterations on these loops. I removed them and problem solved. Are u using Nangate for synthesis?
