Hi all! I am a student, and now I am study digital design in my university.
Could you, please, explain me the difference between clock waveform during the scan test mode and normal mode? I mean duty cycle difference:
normal mode:
Code:
[I]create_clock -period 100 -name clk -waveform {0 50};[/I]
scan test mode:
Code:
[I]set_dtf_signal -view existing_dft -type ScanClock -port clk -timing {45 50};[/I]
So, why we should use different waveforms?
Thank you very much!
