I am doing the function ATPG for a chip.
there are many bidirection ports for the chip, these ports is not the scan port.
How should I deal with them?
Could I ignore their direction, and dont assign a fixed value to its trimode EN control signal?
Or If I want to used them in our ATPG mode,and I assign a fix direction for them,Then when in ATPG mode, I use input ports for stimulus and output ports for result capture, Is that right?
Thank you for your any comments.
