Felix: an Agda category theory for denotational design

Introduction

This library replaces the overgrown denotational-hardware library, which had mixed general category theory with some functionality for hardware design.

Dependencies

• Agda compiler. Works with Agda 2.6.4.
• The Agda standard library (agda-stdlib). Works with agda-stdlib 2.0.
• Haskell ieee754 package (as described under Troubleshooting below).

Troubleshooting

You might see an error message like this:

You can fix this error with:
