I can provide you with a simple example. I've built a simple NAND2 example, which has been verified by DRC, and is running a testbench for IRSIM that does not produce any assertion errors if the gate has been built correctly. When run in Electric, on both versions 9.00 and 8.11, there is no issue with the assertions. However, in Electric 9.00, the output waveform does not display the correct input stimuli, although the output seems correct. I've tried redownloading IRSIM and electric, so I know its (likely) not a corrupt file issue. It almost seems as if the waveform is corrupt for the first 40ns. Even a simple CMOS inversion gate shows the same properties, the gate input does not change in the waveform, even though IRSIM thinks it does. The testbench can be found below:
BEGIN TESTBENCH | stepsize 10 ns stepsize 10 ns print Begin Test............ print ..................... l in1 l in2 s assert out 1 l in1 h in2 s assert out 1 h in1 l in2 s assert out 1 h in1 h in2 s assert out 0 l in1 l in2 s assert out 1 h in1 h in2 s assert out 0 l in1 h in2 s assert out 1 h in1 l in2 s assert out 1 h in1 h in2 s assert out 0 print End Test................... print ........................... print Check to make sure that there are no "Assertion failed" messages END TESTBENCH If you would like, I can provide screenshots of it both working on 8.11 and working incorrectly on 9.00, though you should be easily able to verify the results yourself. I'm not sure though where I'd start looking for the bug? Or if there's some configuration step I've missed I could still try.
