tco requirement inside design

--- Quote Start ---

Hi I'm trying to setup a tco requirement assignment between the clock and a multiplier output(not a pin). i was able to do it while there was a outputPin but now i need it between ff's. classic timing report says ignored due "no path found" or "no such node in netlist" or "synthesised away".

do i need additional assignments?

thanks in advance

Hi,

why do you want to specify a tco for an internal signal ? When you set your clocks Quartus will take care about your internal tsu, tco ...

Kind regards
