PROGRAM:
NAME
s51, savr, sz80 - 8051, AVR and Z80 microcontrollers simulator for SDCC.
SYNOPSIS
s51 [options] filenames
savr [options] filenames
sz80 [options] filenames
WARNING
The information in this man page is an extract from the full documentation of SDCC, and is
limited to the meaning of the options.
For complete and current documentation, refer to the ucSim simulator User Guide.
DESCRIPTION
ucSim is a microcontroller simulator. It is extensible to support different
microcontroller families.
MCS51 family is simulated bys51.
AVR family is simulated by savr.
Z80 processor is simulated by sz80.
Specified files must be names of Intel hex files. Simulator loads them in specified order
into the ROM of the simulated system.
OPTIONS
-t CPU Type of CPU. Recognized types are: 51, 8051, 8751, C51, 80C51, 87C51, 31, 8031,
C31, 80C31, 52, 8052, 8752, C52, 80C52, 87C52, 32, 8032, C32, 80C32, 51R, 51RA,
51RB, 51RC, C51R, C51RA, C51RB, C51RC, 89C51R, 251, C251, DS390, DS390F. Note that
recongition of a CPU type as option does not mean that the simulator can simulate
that kind of CPU. Default type is C51. DS390 supports Dallas DS80C390 dual-dptr
operations, DS390F supports minimal flat24 mode code and dual-dptr operations.
-X freq[k|M]
XTAL frequency is freq Hertz. k or M can be used to specify frequency in kHZ or
MHz. Space is not allowed between the number and the k or M. Default value is
11059200 Hz.
-c file
Open command console on file. Command consoles are on standard input and output by
default. Using this option the console can be opened on any file for example on the
serial interface of the computer.
-Z portnum
Listen for incoming connections on port portnum. Using this option uCsim can serve
multiple consoles. You can get a console by simply telnet into machine running
uCsimto port portnumber. This option is not available on platforms which doesn't
support BSD networking.
-s file
Connect serial interface of the simulated microcontroller to the file. Nothing is
used by default which means that characters transmitted by serial interface of the
simulated microcontroller go to nowhere and it will never receive anything. If you
are going to communicate with serial interface interactively the best idea is to
specify a teminal with -s option.
-S in=file,out=file
Using this option you can specify different files for input and output streams that
uCsim uses to simulate microprocessor's serial interface.
-p prompt
Using this option you can specify any string to be the prompt of command
interpreter, for example:
$ s51 -p "s51> "

s51>
-P Prompt will be a null ('\0') character. This feature can be useful for programs
which controlls simulator through a pipe.
-V Verbose mode. The simulator notifies you about some kind of internal actions for
example interrupts. Messages are printed on command console.
-v Print out version number and stop.
-H Print out types of known CPUs. Names printed out by this option can be used to
determine CPU type using -t option.
-h Print out a short help about the options and stop.
