Honored ContributorHi Pete,
I still believe its a bug. Here's why. Changing triggers does not require any recompile or place and route. Neither does changing the state machine comparison values IF you turn on the option(s) for allowing it which I did. The previous state machine I had was 2 instead of 3 states and I had 2 instead of 3 trigger conditions. It worked perfectly fine in that prior version whether I changed trigger conditions, state machine values, etc.. So, just increasing the number of trigger conditions and states should not matter. Now, here's what I found out this afternoon which confirms it a bug. With my new state machine/trigger conditions, I did a comparison of the .stp file, before I changed a single trigger condition, with that after changing the trigger condition and saving a new .stp file. I then did a comparison of the two files. There were several things that were different, but the one thing that stood out was the later file was missing a CRC string contained in the original file. So I copied the string and put it in the right location and all works well - until I go change the trigger condition and have to do this again! Definitely a bug. :) Can you get an FAE to contact me and I can send him some files. Thanks Kirk Weedman Verilog RTL Design Engineer Western Digital
