This library aims to be a comprehensive 7400 series library for Logisim for designing logical circuits and for educational purposes.

The library should be compatible both with original Logisim and logisim-evolution.

To meet these goals, the following design guidelines are met:

• Circuits are build from a minimal set of built-in components.
• The pin layout matches the DIP pinout of the corresponding ICs.
• Automated tests are provided.
• Labels must conform to VHDL, i.e. start with a letter and contain only letters, digits, or underscores.

See documentation for details. Currently, circuits from other libraries are being integrated will later be redesigned to meet the guidelines.
