How to fix timing in synthesis - Eternal Learning

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.
