16 Ways To Fix Setup and Hold Time Violations - EDN

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. Written on July 5, 2024 WebThere can be multiple approaches to address IO timing challenges. Let’s discuss a few of them: 1- IO Flop Bound at Placement Stage It is a fundamental and common approach to fix IO timing. In this approach, we need to identify the violated IO ports and make a flop bound nearby to ports. WebSolution. If the Hold Time Violation is associated with an OFFSET IN constraint, the data path is faster than the clock path. Either increase the delay associated with the data path … rays in central point

WebTo fix IO timing violation, we need to analyze the cause of the timing violations so that it can be fixed at the right stage. In this design, reg2out setup violation reported at placement stage. To meet the internal timing, tool placed those flops a little away from the output port. WebSETUP FIXES During Placement Stage: Timing path groups: We can use this option to resolve Setup timing during placement stage. Groups a set of paths or endpoints for cost function calculations. The delay cost function is the sum of all groups (weight * violation), where violation is the amount for which setup was violated for all paths within the group.
