TIMING WINDOW MANIPULATION FOR NOISE REDUCTION

Timing window manipulation for noise reduction includes: selecting a path of a circuit design having a timing violation from a timing analysis of a victim window; determining an aggressor net coupled to a victim net along the path; determining a propagation path through the determined aggressor net;...

Zusammenfassung:Timing window manipulation for noise reduction includes: selecting a path of a circuit design having a timing violation from a timing analysis of a victim window; determining an aggressor net coupled to a victim net along the path; determining a propagation path through the determined aggressor net; propagating a victim window value backward through the propagation path, the victim window value associated with the victim net; and modifying circuit characteristics of the circuit design within a switching window associated with the aggressor net based at least on the propagated victim window value.
