Instruction Set Simulator (ISS) for microcontrollers
µCsim can be used to simulate
microcontrollers. It supports
- Intel (MCS51 family, MCS48, MCS80, MCS85)
- XA51,
- AVR core,
- Z80 (Z80, Z180, GB80, EZ80, Z80N, R800),
- TLCS90,
- Rabbit (r2k, r3k, r4k, r5k)
- Motorola (6800, 68hc08, 6809, 68hc11, 68hc12)
- MOS6502,
- ST7,
- STM8,
- Padauk (pdk13, pdk14, pdk15, pdk16)
- PicoBlaze,
- p1516,
p2223 soft processors,
- F8 soft processor,
- OISC processors
(URISC,
MISC16)
It runs on Linux, Windows, OSX, BSD, and other systems.
See what's new in current version.
You can download µCsim from the following
places:
Use precompiled binary packages
UNIX version is distributed in source, as well as
in pre-compiled debian packages for i386 and amd64
architectures.
Windows version distributed as a setup executable and as a
portable zip package.
How to compile from source
- 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.
- Make sure, that following packages are installed on your
system: make (GNU make is required),
bison (or yacc), flex (or lex), libncurses-dev.
You will need a C++ compiler as well.
- 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 files will be placed
in bin subdirectory.
- Compile the package with make command,
or gmake if GNU make has that name.
- Install
executables ucsim_i8051, 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 the user.
Features of the simulator
- Processor types.
The simulator can simulate different types of microcontrollers.
- Multiple consoles.
The simulator can handle more than one command console 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 connect them together.
- Simulator interface.
This is a
special interface which provides services for the simulated
program. These services can be used to control the simulator
(for example run/stop) and access some host features (print,
file I/O).
- VCD file I/O.
This is a special virtual hardware peripheral which can monitor changes
of a memory location (or a bit in MCS51 where bit address space is
available) and write out changes to a VCD file. It can also be used to
replay events from a VCD file in order to simulate external events.
- Peripheral displays.
Textual
user interfaces which can show information about a
peripheral. Some of them are interactive and can be used to
provide external input data for the simulated system (port,
uart).
- Command syntax
and command
reference, expressions.
The simulator can be controlled via a command line
interface. It accepts simple commands.
