Clkbuf是什么
WebOpenSTA for doing timing analysis. Command to use: run_synthesis Once completed, it will report out the design statistics. Here is an example for design picorv32a. You can do some simple analysis on the design: Flop Ratio = Number of Flops / Total number of cells. Buffer Ratio = Total number of buffers / Total number of cells.

WebThe clkbuf_inhibit is the default attribute to set on a wire to prevent automatic clock buffer insertion by clkbufmap. This behaviour can be overridden by providing a custom selection to clkbufmap. The invertible_pin attribute can be set on a port to mark it as invertible via a cell parameter. The name of the inversion parameter is specified as ...
