Apate - a visual CPU simulator for use in education

This simulator is a tool for students to learn the inner workings of a CPU. Based on the RISC V instruction set (RV32I) it provides a visual step by step guide through the flow of a CPU. Watch the introduction video!

Features

• Step by step guid trough the CPU
• See the current instruction and what that instruciton does
• Information about each element and signal of the CPU
• See all registers, memory
• Run examples
• Compile your own code with integrated editor and compiler
• Complex CPU elements simplified
• Not focused on speed, verification, completeness or correct depiction of HDL but on principles of teaching

Under the hood

• Runs on electron
• Visualisation with three.js and SVGLoader
• Interface with Angular
• Custom JavaScript ELF parser
• Custom JavaScript instruciton decoder
• Custom JavaSript CPU based RV32I ISA
