WebJul 30, 2024 · 3. Static Timing Simulation. This is done post mapping. Post map timing report gives the signal path delays. After place and route, timing report takes the timing delay information. This provides a complete timing summary of the design. Applications of FPGA. FPGAs have gained a quick acceptance over the past decades. WebThis timing report is from my project, which has the circuit shown below. Note how lines 35-46 of the timing report show incremental delays (Incr(ns)) along the clock path starting at the FPGA clock input, CLK_IN1_P, and ending at the clock-pin of the DAT1_reg. I think this is the information you are looking for?

WebThe following strategy helps analyze the timing reports and fix violations: 1. Review the constraints coverage report and ensure that the design is properly constrained. 2. Review the timing reports and understand the violating paths if timing violations are present. Start with fixing the critical paths with the largest negative slack. 3.
