Hi,
I am trying to learn how to use Tetramax as a fault simulator. I want to learn how to use it on a simple sequential circuit like s27, the Verilog code can be found here... https://web.archive.org/web/20071120021748/http://www.fm.vslib.cz/~kes/asic/iscas/s27/s27.v The s27 circuit should have 27 fault sites and therefore 54 different faults. But when I use the command add_faults -all in Tetramax it only comes up with 34 faults. Is there a way to find out what faults are missing and then add them to the fault list?
Also, is there a way to make the flip-flops in the s27 circuit part of a scan chain?
One last question, how would I set up with .spf file?
Thank you to anyone that can help me!
