I agree. If it is a simple state machine then surely there must be a simulator for it? Beats the heck out of building & debugging. ESP - Any plans for one?

Sorry, we don't have this planned, but we are open to suggestions.

Do you have any ideas how would such emulator work?
If this would be a standalone desktop tool, this would be of limited use since it's hard to test interaction between the main program and the ULP program, right?
If emulation would happen on the ESP itself (using one of the Xtensa cores), then it's still hard to make the timing work the same as on the real ULP.
