For the 8051, the 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.
uCsim is available for two platforms: DOS (MCS51 only) and UNIX but DOS version is not supported any more. DOS version is not finished so I call it demo version and it is available in binary only. Limitations of DOS version are:
- There is no built in help available;
- Some of the utilities are not working, for example calculator, bit simulator;
- Serial line works in mode 1 independently of mode bits.
Starting the Simulator
There are separate programs to simulate different microcontroller families:
MCS51 family is simulated by s51
AVR family is simulated by savr
Z80 processor is simulated by sz80
XA family is simulated by sxa
HC08 processor is simulated by shc08
The program can be started using following command:
C:\> s51 [input file]Parameter is optional. If it specified it must be the name of an Intel hex file.
For more details, please see its documentation. This is an overview and I will write about this simulator later.
