Occasional ContributorClock missing from Timing Analyzer - Report Setup Summary
I have a clock mux along the lines in "ug-qps-03-design-recommendations.pdf" I have set the output clock to be a Global Clock in the Assignment Editor and I give it's minimum period in the sdc file....

Occasional ContributorI'm sorry, I don't quite follow the philosophy.
The HDMI_TX_CLK is the output from a clock multiplexer that is fed by a couple of PLLs producing a total of 4 clocks, namely standard video clocks, the fastest being 150MHz.
The clock signal feeding the PLLs is a single 25MHz clock.

Super ContributorDo all the clocks of the PLL (input reference, output clocks) appear in the clocks report (Report Clocks)?
