WebTransition violations can be fixed by either by upsizing the driver, or perhaps splitting the net by insert a buffer which would effectively split the load driven by a cell and hence improve transition. Buffer insertion would also help fixing max_capacitance violations as well. After clock DRV fixing, you can perhaps do a data DRC/DRV fixing. WebMay 22, 2012 · Activity points. 2,176. This errors signifies that the clk changes at the same time as your RB while a hold of 1000 has been defined as minimum hold requirement. Check whether the path is a false path. If so declare it as a false path. Else you have to probe for the reason of failure to meet the timing. May 19, 2012.
