This is a way to put lots of designs onto one chip and still have access to them all. You can see [all of the technical details here](https://github.com/mattvenn/scan_wrapper).\n\nAfter that, the action uses the open source ASIC tool called [OpenLane](https://www.zerotoasiccourse.com/terminology/openlane/) to build the files needed to fabricate an ASIC.\n\n# What files get made?\n\nWhen the action is complete, you can [click here](https://github.com/mattvenn/wokwi-verilog-gds-test/actions) to see the latest build of your design. You need to download the zip file and take a look at the contents:\n\n* gds_render.svg - picture of your ASIC design\n* gds.html - zoomable picture of your ASIC design\n* runs/wokwi/reports/final_summary_report.csv  - CSV file with lots of details about the design\n* runs/wokwi/reports/synthesis/1-synthesis.stat.rpt.strategy4 - list of the [standard cells](https://www.zerotoasiccourse.com/terminology/standardcell/) used by your design\n* runs/wokwi/results/final/gds/user_module.gds - the final [GDS](https://www.zerotoasiccourse.com/terminology/gds2/) file needed to make your design\n\n# What next?\n\n* Share your GDS on twitter, tag it #tinytapeout and [link me](https://twitter.com/matthewvenn)!\n* [Submit it to be made](https://docs.google.com/forms/d/e/1FAIpQLSc3ZF0AHKD3LoZRSmKX5byl-0AzrSK8ADeh0DtkZQX0bbr16w/viewform?usp=sf_link)\n* [Join the community](https://discord.gg/rPK2nSjxy8)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcpldcpu%2Ftinydice","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcpldcpu%2Ftinydice","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcpldcpu%2Ftinydice/lists"}
