Methods to fix timing violations in synthesis stage

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. WebTiming Violations due to State-machine Optimization: Use one-hot encoding for the states. This is a good choice for optimizing speed.

WebWays to address hold violation: 1) Add more data path delay. End point buffering is usually preferred as that won’t affect the previous and next stage. 2) Downsize the datapath cells to increase the transition time which eventually increases the cell delay. 3) Change the cell type to HVT.
