WebThe challenge of CPPR is that the amount of pessimism to be removed is path-dependent. Existing solutions fall into two categories, critical-path-based approach and exhaustive search approach. The critical-path-based approach first identifies critical paths without CPPR consideration and then re-evaluates these identified paths with CPPR.

Or in another world, we can say switching of a signal in one net can interfere in the neighbouring net, which is called crosstalk. When a signal switches, it may affect the voltage waveform of a neighbouring net. queen comforter sets with decorative pillows
