SIMDE is a computer simulator with a strong focus on assisting in learning and education. As a didactic simulator, SIMDE aims to supercharge the teaching of computer architecture principles with a pragmatic, learn-by-doing approach.

When used in supporting educational practices, SIMDE shines both for reproducing architectural concepts, such as Tomasulo's algorithm and representing organizational structures, like re-order buffers.

This is how SIMDE looks in action

Features

Building from sources

Prerequisites

Make sure that the following tools are installed in your system:

• Node.js (version >=18).
• pnpm (version >=8).

Build steps

1. Install the project dependencies:

pnpm install --frozen-lockfile

2. Build the static site:
