Default generated clocks

Hi,

I need a suggestion in handling the generated clocks for synthesis, and DFT.
What kind of constraints would be used for generated-clocks during
synthesis, and DFT design.

Thanking you for help.

Best regards,
vic

Same constraints as with any other clock signal; namely, setup time and hold
time for inputs, clock to output for outputs

If you are usinng DCyou can use the create_generated_clock constraint
Check out DC's man pages about usimg this command
