ARMv6m_Simulator

Simple Simulator of ARMv6m instructions

The ARMv6m Simulator is a simulator for testing ARMv6m instruction sets. You can use STEP execution, breakpoint, etc. in CLI environment by using bin file compiled with armv6m compiler.

Scope Supported

Mode

Only support Thread mode

32bit Instruction

• BL

Points to consider when using

• ONLY Thread Mode
• Do Not consider: Pipeline, Cycle Timing, Exceptions, Memory Map
• Just consider : R0 ~ R15, NZCV flags

Usage

• How quit this program : just type 'q' and enter.
• Show break point : just type 'b' and enter.
• Set break point : type 'b' and hex address ("b 4A")
• Set register : type 'R n' and hex address ("R 1 4A")
• Show memory : type 'd' and hex address ("d 4A")
• Step by step debug : just type 's' and enter.
• Run(stop at breakpoint): just type 'r' and enter.
• Verbose : toogle Run verbosity with 'v'
• Finally, it will store the memory in dumpfile!

Compilation and execution

• Testsuite:

make test
./test_ARMv6m_Simulator

• Simulator:

make
./ARMv6m_Simulator
How to Use : $./(compiled program) (input file name) (dump file name)
