Software simulator for microcontrollers
µCsim can be used to simulate microcontrollers. It supports MCS51 family. AVR core, Z80, HC08 and XA are supported by UNIX version only.
Download
Simulator is available for two platforms: DOS (MCS51 only) and UNIX but DOS version is not supported any more. DOS version is not finished so I call it demo version and it is available in binary only. Limitations of DOS version are:
There is no built in help available;
Some of the utilities are not working, for example calculator, bit simulator;
Serial line works in mode 1 independently of mode bits.
I used this simulator to verify my applications and I never used missing feautres mentioned above, so I think that this "demo" version can be usefull anyway.
