> Non-x86 architectures > SIMA: simple minimalistic core simulator

SIMA is the minimalistic disassembler and core simulator for ARM Cortex-M MCU family. Currently it support only ARMv6-M instruction set, which used in the Cortex-M0 MCU's (for example STM32F0).
SIMA supports limited source-level debug.
Input executable formats:
- only raw binary image (no source level debug)
- raw binary + appropriate *.fas file (source level debug, specialy feature for FASMARM)
- ELF executable with DWARF-2 debug info (commonly used source level debug)
SIMA has easily upgradeable architecture, all that is needed for extension (eg to Cortex-M3, M4) - to write DLL with disassembler and instructions simulator, and peripheral memory model.
Now supported only Cortex-M0 STM32 (cm0_core.dll + stm32f0xx_periph_memory.dll).

You have many *.asm files in the attachment. Which is the start source?
Would it make more sense to have only one *.asm and the rest as *.inc? One *.asm for one *.exe. Just IMO, you can do whatever you want of course.

There is two main source files for two DLL's.
- cm0_core.asm (for cm0_core.dll);
- stm32f0xx_periph_memory.asm (for stm32f0xx_periph_memory.dll).
sima.exe linked with polink from many object and resource files.
Source code for sima.exe I will publish later. Maybe. Too many sources and resources
A GUI already contains enough functions.
A help and collaboration is needed only in development of disassembler and simulator engine, but this part of code - in DLL's. For this purpose DLL's was written in pure FASM without any third party tools.
Development of project is implied by writing a new libraries according to samples, cm0_core.dll and stm32f0xx_periph_memory.dll (for example cm3_core.dll for Cortex-M3).
MCU peripherals is very complex for understanding and simulation, therefore only MCU core is simulated today.

Hi all! SIMA 1.1 is now available.
Fixed many bugs in disassembler and simulator, GUI also has been improved.
Here is full sources.
