RISC-V Assembler with GUI

A Python-based assembler that converts RISC-V assembly code into 32-bit binary instructions.

This is a Python-based assembler for RISC-V assembly language, featuring both a graphical user interface (GUI) and command-line functionality. It translates RISC-V instructions into 32-bit machine code and supports standard and some extended (BONUS) instructions.

✨ Features

• ✅ RISC-V instruction parsing and binary conversion
• 🖥️ GUI using tkinter for code input/output
• 🧾 Command-line support for scripting or automation
• 🛠️ Bonus custom instructions (mul, rst, rvrs, halt)
• ⚠️ Syntax and label validation with helpful error output
• 📂 File operations: Open, Save, Save As, New
• 🧪 Testcase auto-generation utilities

🧠 Supported Instruction Types

• R-type: add, sub, slt, sltu, xor, sll, srl, or, and, mul
• I-type: lw, addi, sltiu, jalr
• S-type: sw
• B-type: beq, bne, blt, bge, bltu, bgeu
• U-type: lui, auipc
• J-type: jal
• BONUS: rst, rvrs, halt

🧪 Testcase Generators

• testcasegenerator() – generates all standard instruction permutations
• bonustestcases() – generates all bonus instruction permutations

🚀 Usage

GUI Mode (default):
