This is a Tiny Tapeout project

It implements a simple, annoying two-tone siren and makes patterns on a seven segment display.

This project is implemented in wokwi. The best way to understand what it does is to use the simulation:

1. Go to https://wokwi.com/projects/348242239268323922
2. Press the Play Button.
3. Change the setting of switch 8 to change between the two kinds of patterns.

The remainder of this file is the README from the submission template.

How to change the Wokwi project

Edit the info.yaml and change the wokwi_id to match your project.

How to enable the GitHub actions to build the ASIC files

Please see the instructions for:

• Enabling GitHub Actions
• Enabling GitHub Pages

How does it work?

When you edit the info.yaml to choose a different ID, the GitHub Action will fetch the digital netlist of your design from Wokwi.

After that, the action uses the open source ASIC tool called OpenLane to build the files needed to fabricate an ASIC.
