ucsim1

Usage

Overview

uCsim is a microcontroller, microprocessor simulator for several processor families. It can be started as ucsim_XXXX command, where XXXX specifies the simulated processor type. Eg. ucsim_51 starts Intel MCS51 microcontroller simulator, ucsim_z80 starts Zilog Z80 microprocessor simulator, etc.

Options

Options of the command

-a nr

Specify size of variable space (default=256).

-A

Force use colored output, remove effect of -b and -q on colors.

-b

Black & white (non-color) theme.

-B

Beep on breakpoints.

-c file

Open command console on file (use - for std in/out).

-C file

Read initial commands from file and execute them.

-e command

Execute command at program startup (after config file).

-E

Go, start simulation in emulation mode.

-g

Go, start simulation.

-G

Go, start simulation, quit on stop.

-h

Print out this help and quit.

-H

Print out types of known CPUs and quit.

-I options

options is a comma separated list of options according to simulator interface. Known options are:
if=memory[address] turn on interface on given memory location.
in=file specify input file for IO.
out=file specify output file for IO.

-k portnum

Use localhost:portnum for serial I/O. This option is obsolete, use -S instead.

-l

Use colors of the light theme (default is dark).

-m

Return value of simulated main() function.

-o colors

List of color specification: what=colspec,... where colspec is : separated list of color options e.g.: prompt=b:white:black (bold white on black).

-p prompt

Specify string for prompt.

-P

Prompt is a null ('\0') character.

-q

Quiet mode, print less information (implies -b).

-R seed

Set the random number generator seed.

-s file

Connect serial interface uart0 to file This option is obsolete, use -S instead.

-S options

options is a comma separated list of options according to serial interface. Know options are:
uart=nr number of uart (default=0)
in=file serial input will be read from file named `file'.
out=file serial output will be written to `file'.
port=nr use localhost:nr as server for serial line.
iport=nr use localhost:nr as server for serial input.
oport=nr use localhost:nr as server for serial onput.
raw perform non-interactive communication even on tty.

-t cpu_type

Specifies type of the controller. Use -H to list possible values.

-U uartnr

Use std console as terminal for UART id=uartnr.

-u hw

Use std console as display for specified hw.

-v

Print out version number and quit.

-V

Verbose mode.

-w

Writable flash.

-X freq[k|M]

XTAL frequency in Hz, Use k or M suffix to specify frequency in kHz or MHz.

-z portnum

Listen portnum for command console.

-Z portnum

Listen portnum for command console (no console on stdio).
