RISC-V Simulator

A web-based application for visualizing RISC-V processor register states and datapath. Users can write and execute RISC-V assembly code, observe register state changes during instruction execution, and track instruction flow through a visual datapath. The simulator supports the RV32I base instruction set and the RV32M extension. - RISC-V Assembly Editor: Write and edit RISC-V assembly code with syntax highlighting - RV32I and RV32M Support: Full implementation of base integer (I) and multiplication/division (M) extensions - Instruction Execution: Step-by-step or continuous execution of RISC-V programs - Register State Visualization: Real-time display of register values during program execution - Memory Visualization: View and monitor memory contents during program execution - Output Console: View program output from system calls - Predefined Example Programs: Load example programs to learn RISC-V programming - Multiple Datapath Models: Choose between basic datapath and pipelined datapath visualizations - Pipeline Hazard Handling: Support for data forwarding and control hazard resolution - Performance Analysis: Real-time statistics on CPI - Cache Simulation: Cache with hit/miss statistics - Interactive Simulation: Pause, step, and reset simulation at any point - React: User interface construction - Tailwind CSS: Rapid responsive interface development - Vite: Modern build tool - ReactFlow: Datapath visualization - Zustand: State management RISC-V Simulator is the open-source project Haoziwan/Interactive-RISC-V-Simulator (https://github.com/Haoziwan/Interactive-RISC-V-Simulator) by Haoziwan, released under MIT. Ion packages it unmodified from commit 293745321cb3, adding only a manifest, an icon and a storage compatibility script.
