# Software simulator for microcontrollers

µCsim can be used to simulate microcontrollers. It supports MCS51 family, AVR core, Z80, HC08, ST7, STM8, TLCS90 and XA51. It can run on Linux, Windows, OSX, BSD, and other systems.
See what's new in current version.

## Download

There are two places where you can download µCsim from:

1. SDCC homepage. µCsim is part of the SDCC (Small Device C Compiler) project. You can download source of SDCC and precompiled binaries from http://sdcc.sf.net.
2. µCsim site. Standalone source package is available on the µCsim web site:
   http://mazsola.iit.uni-miskolc.hu/ucsim/download

## How to install

UNIX version is distributed in source.

1. Get archive file, uncompress and untar it. These steps will produce a directory ucsim-X.Y.Z where X.Y.Z is the version number.
2. Go to the directory and configure the package. Issue `configure` command. It will determine your system and make Makefile. Installation directory can be specified with `--prefix=dir` option to the `configure`. Default directory is `/usr/local`. Executable file will be placed in `bin` subdirectory.
3. Compile the package with `make` command.
4. Install executables s51, savr, shc08, sxa, sz80, etc. to any directory you want. It can be done with `make install` command which will place files in installation directory specified with `--prefix=dir` option of `configure`. Note that you may have to have special privilege to do this if installation directory is not writeable by you.

## How to use

- Invocation.
  Starting the simulator program.

Features of the simulator

- Code analyser.
  The simulator tries to figure out places of valid instructions in code area.
- Processor types.
  The simulator can simulate different type of microcontrollers.
- Multiple consoles.
  The simulator can handle more than one command consoles and accepts command from multiple sources. It also can be driven by other programs such as debugger interfaces.
- Serial interfaces.
  The simulator can virtually connect a terminal to serial interface of the simulated CPU.
- Memory simulation.
  Simulated CPU provides address spaces, storage is simulated by memory chips, address decoders connects them together.
- Simulator interface.
  This is a special interface which provides services for the simulated program. This services can be used to control the simulator (for example run/stop) and access some host features (print, file I/O).
- Command syntax and command reference. (Now updated up to 0.6)
  The simulator can be controlled via a command line interface. It accepts simple commands.
