Is it possible to define a pin as the scan clock?
Ex the output of a clock gen module as the scan clock in the set_dft_signal. I have been using the following statement set_dft_signal -view existing_dft -type ScanMasterClock -port CLK -timing [list 45 55], but now I came across a situation where I need to use the output port of an internal module.
Any help will be appreciated
 

I only used ports as ScanClock. But for scan shift/scan output stuff, I used internal signals, because I did not manually connect them to ports. I left the job to stitching tool to connect them.

set_dft_signal -view spec -type ScanDataOut -port ioxxx -hookup_pin "uxxx/xxx"

So it seems that you need to use "spec" instead of "existing" and use "hookup_pin" opt.

But you should be able to manually connect, since dft can only control ports... the scan clock should be eventually from outside of the chip
