WebWith scan cells supporting functional/mission mode and scan mode, in general scan test is working as follows[1]: Shifting into scan chains is used to directly set the state of the DUT, then one or more clock cycles of normal operation is applied, optionally DUT outputs are checked for correct values, and finally the resulting state is shifted ... WebApr 7, 2024 · I am trying to implement this in Verilog and I do not know how to code the channels (or inputs) so that they are continuously scanning and waiting for their pulses.
