About RARS
RARS, the RISC-V Assembler, Simulator, and Runtime, will assemble and simulate the execution
of RISC-V assembly language programs. Its primary goal is to be an effective development
environment for people getting started with RISC-V.
Features:
- RISC-V IMFDN Base (riscv32 and riscv64)
- Several system calls that match behaviour from MARS or SPIKE.
- Support for debugging using breakpoints and/or ebreak
- Side by side comparison from psuedo-instruction to machine code with intermediate steps
- Multifile assembly using either files open or a directory
Environment Variables:
- RARS_JAVA (Default: none): Passes arguments directly to the Java command (Will override other environment variables)
- RARS_SCALE (Default: Screen width / 1920): Sets the sun.java2d.uiScale property (See documentation at [link removed])
