http://www.physics.brocku.ca/Courses/2P32/lab-manual/pic-assembler.pdfsimulator for PIC microcontrollerIt's a tool that is a combination compiler/ide/emulator/control device for a home-grown digital Electronics lab platform, called PiCLab.
picl is freely available, but it really does require the development board itself to make full use of it, even if it works happily without one.links:
