Projects / EVBU


EVBU simulates the execution of a 68HC11 microcontroller as well as the BUFFALO monitor program that provides a command line interface to executing and debugging programs. A graphical waveform panel allows simulation of 68HC11 peripherals like timers, input capture, etc. Additional features include symbolic debugging and cycle counting.
