Faster the signals more sensitive they areCareful planning is requiredDenser the design, harder it is to route all signals in a timely mannerTrial and error is not a strategyTraditional tools fall short in helping PCB Designers speed timing closure
Now that the Timing system has been set up properly. We are now ready to begin some delay tuning. Use the tuning functions to start in the most difficult area – the middle and let it push/shove open to build space to meet the delay constraints. Select the appropriate data and after the tool is complete, it should display the image shown in the bottom half of the slide with all of the nets tuned properly.
