I was wondering if it was possible to disable simulation of the ports? I am not using them for serial communication and I want to use these bit addressable registers another way. I am simulating a M8051EW and everytime that I reset the micro-controller the ports all reset to 0xFF. I don't want the micro-controler to reset these registers. I want them to keep the same value that they had before the reset occured. How do I turn off simulation of different device features?
"There is a 0,0001% possibility that some stupid developer of a deviate would leave the port pins random after a reset. Visualize a medical device with random outputs after a power glitch OUCH." But, again, this is an IP core - so he's probably also developing the rest of the system, and can design it accordingly. "if, for every answer one should analyze whether the OP is using a deviate, rather than a derivative" You could always just say, "I don't recognise that part - I'll just ignore it..."
