The information in this man page is an extract from the full documentation of SDCCc , and is limited to the meaning of the options.

For complete and current documentation, refer to the ucSim simulator User Guidec .

ucSimc is a microcontroller simulator. It is extensible to support different microcontroller families.

MCS51c family is simulated byc s51c .

AVRc family is simulated by savrc .

Z80c processor is simulated by sz80c .

Specified files must be names of Intel hex files. Simulator loads them in specified order into the ROM of the simulated system.

-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 freqc Hertz. kc or Mc can be used to specify frequency in kHZ or MHz. Space is not allowed between the number and the kc or Mc . Default value is 11059200 Hz.

-c file

Open command console on filec . 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 portnumc . Using this option uCsim can serve multiple consoles. You can get a console by simply telnet into machine running uCsimc to port portnumberc . This option is not available on platforms which doesn't support BSD networking.

-s file

Connect serial interface of the simulated microcontroller to the filec . 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 -sc option.

-S in=file,out=file

Using this option you can specify different files for input and output streams that uCsimc 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.
