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:

How to install

UNIX version is distributed in source, pre-compiled debian stable package for i386 and amd64 architecture.

Windows version distributed as a setup executable and as a portable zip package.

How to compile from 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. Make sure, that following packages are installed on your system: make, bison (or yacc), flex (or lex), libncurses-dev. You will need a C and a C++ compiler as well.
  3. Go to the directory and configure the package. Issue configure command. It will determine your system and produce 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.
  4. Compile the package with make command.
  5. Install executables ucsim_51, ucsim_avr, ucsim_hc08, ucsim_xa, ucsim_z80, 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 writable by you.
