     Hi Vipul,

     Can you elaborate a little on what you mean by "test procedure"?

    By procedure I mean the the definition on shift, load PI, measure PO, capture data, shift out. I want to edit these procedures and want to know where it is defined.

     

    Thanks,

    Vipul

     Those are called "sequences" in Encounter Test.  You can write out the sequences for a testmode as follows:

       report_sequences TESTMODE=FULLSCAN format=node

     These sequences can be copied to another file and edited as desired.  You can then re-build the testmode using these modified sequences. Consult the ET Modelling Users Guide for more information.

     FYI, the timing of signals is not defined in the sequence... only the ordering of events.  You can adjust the timing of specific signals during write_vectors.

     Modifying the sequences is somewhat advanced, and it shouldn't need to be done in normal circumstances.  Why do you feel you need to edit the sequences?

    Hi bmiller,

     

       Thanks for the explaination. I was just correlating with the theory of ATPG and the tool operation, so just wanted to know how the tool works.
