Abstract :
This mini-tutorial covers recent research on clock-network tuning. It starts with SPICE-accurate optimizations used in winning entries at the ISPD 2009 and 2010 clock-network synthesis contests. After comparing clock trees to meshes, it outlines a recent redundant clock-network topology that retains most advantages of clock trees, but improves robustness to PVT variations. It also shows how to incorporate clock-network synthesis into global placement to reduce dynamic power and insertion delay.
