WebAll the clock tree spec file entries are documented in the EDI User Guide, "Synthesizing Clock Trees" chapter. Here's a summary of those you mentioned above: MaxDelay = maximum phase delay constraint (default 10 ns) MinDelay = minimum phase delay constraint (default 0 ns) MaxSkew = maximum skew between sinks (default 300ps) WebAug 6, 2012 · EDA tool role in clock tree synthesis Today, a lot of R&D has been done on EDA tools to design an ideal clock tree. The CTS engines of these tools support most of the SOC requirements to design a robust clock tree. These tools even generate clock spec definitions from SDC(timing constraint files).
