WebIn our design, we instantiate a library clock gating cell ("DLSG1") to do functional clock gating at the RTL level. This cell has an SE input which is left unconnected in the RTL … WebPost control limits your ability to check proper operation of the CG latch if not mistaken. I suggest you check your target standard cell library to determine what kind of clock gating cells are available. In many cases only one type is available. For example: In this case, you would want to use precontrol. If you chose post-control RC would be ...
