warning:tsca_clk was determined to be a clock but was found without an associated clo

Just create a virtual clock with required frequency and waveform parameters.

hi,

virtual clock? I have no idea about the required waveform.

for example,

create_clock -period 2.000 -name tsca_clk tsca_clk -waveform {0 1} ?

can the above constraints work correctly?

thx :)
