Learn to create digital designs and then get them fabricated on actual silicon using Tiny Tapeout and efabless
Fork this repository so you can make changes
Use wokwi or Verilog to create a digital design.
Edit the info.yaml file to specify all the fields. Don't forget to set the clock_hz field to something appropriate for your design (pretty much anything between 10 and 40000000 Hz will be accepted).
Commit your changes and push up to the repository.
Github actions will run on each commit, and you can find them under the actions tab.
Once the run is complete, click on the action and you'll find an fpga_bitstream zip file to download.
Grab that, unzip it, and within you'll find the tt_fpga.uf2 file. Copy that UF2 to the FPGAUPDATE drive. The project should start running a few seconds later.
The development boards will pop up the FPGAUpdate drive when they are plugged into USB.
These boards map well to Tiny Tapeout projects as they have:
-
8 inputs, connected to the piano switch on the left, which map to
ui_in[7:0]; -
8 GPIO on PMOD1, similar to the bidirection PMOD on TT demoboards
uio_in/uio_out[7:0]; and -
8 output IO, which go both to the 7-segment display and to PMOD2, which are the
uo_out[7:0]
The project will, by default, be clocked at the rate you specified in the info.yaml (or as close as possible to that rate). To enable single stepping ("manual" clocking), hold the switch on the top right (next to the USB port) and keep it held as you plug into USB.
Once it's powered-up, you may release the switch and then every press will clock the project once.
Tiny Tapeout is an educational project that aims to make it easier and cheaper than ever to get your digital and analog designs manufactured on a real chip.
