Hi
When defining DFT signals in Scan insertion using RC we use an option called hook up polarity. what does that mean. I am not clear from the explanation given in the Cadence manual.

| Not 100% sure, but perhaps its whether the test/scan signal is active high or active low.

-active is used to define the polarity of the PI signal
-hookup -is used to define the polarity of the signal at the core level connected to the PI.
I think this will clear your doubt
