Ultimate Guide: Clock Tree Synthesis - AnySilicon
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). A typical clock spec file includes: city of alton mayor

WebNov 23, 2006 · I have created clock tree specification file, but my generated clocks are missing in clock tree specification file. Now the problem is how to build clock tree for generated clocks Thanks Rahul . Nov 22, 2006 #2 Y. yln2k2 Member level 5.

The easiest way I can recommend to get this list of nets is using dbGet. WebcreateClockTreeSpec (the TCL command that drives automatic clock tree spec file generation) doesn't have a productized ability to derive ClkGroups as of 9.1.USR2. It write blank statements as a place-holder for users to fill in on their own: #-- Clock Group --#ClkGroup #+ dom fashion atacado
