emulsiV

emulsiV is a visual simulator for Virgule, a minimal CPU core implementation based on the RISC-V architecture. This simulator is intended to be used as a tool for teaching the basics of computer architecture.

The user interface shows the structure of the datapath and animates the data transfers between functional units. The execution of a single instruction is decomposed into several steps (fetch, decode, ALU, mem/reg, PC) for educational reasons, but the intent is not to reflect a specific sequencer or pipeline implementation. In fact, we don't plan to simulate a pipeline in more detail.

emulsiV is free software and is distributed under the terms of the Mozilla Public License 2.0. It is developed by Guillaume Savaton, teacher, researcher and engineer at ESEO.

Running the simulator locally

Due to the security policies in recent web browsers, some features will only work if the simulator is served by a web server. We provide facilities to automate the process.

Install npm and run the following command from the root of the source tree:

npm install

This command starts a local web server and opens the simulator in a web browser:

npm start

Development

Check the JavaScript source code:

npm run lint

This command starts a local web server and runs the unit tests from the test folder:

npm test
