WebThe process of fixing timing violation, and implement the fixes back to the PNR netlist, is referrred to as Engineering Change order (ECO). ... The best way to fix max_capacitance and transition violation, is to either increase … 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.

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. WebWhat is timing violation in VLSI? If m < H , it results into timing violation, called as Hold violation. This means, that the combinational logic delay is very less and hence data …

WebWe will discuss various ways to fix timing in synthesis. 1. Validating timing Constraints.
