What will you make?
A Nyan Cat cartoon only visible through a microscope?
A 555 timer with a back door serial port?
A native hardware BrainF*ck processor?
A custom 6502 with a new Z register for your Apple II?
Bitsliced RISC-V?
Why PNG?
It is standard, it is easy to support, and a huge number of tools and libraries already exist to support creating and viewing PNG files.
The PNG file format opens the door for a wide range of people to easily develop new silicon design tools and workflows. Some people will use MS Paint to draw their layouts by hand while others write Haskell utilities to automatically generate layouts from VHDL descriptions. And everything in between.
Why so low resolution?
To make it cheap and fast and approachable. Note that the venerable 6502 and stalwart 8080 can both be fabricated on this system!
We hope to add higher spec processes and additional layer types as demand justifies them. What would you like to see next?
Where?
All chips are fabricated in New York City.
Why NYC?
Because chips fabricated using deionized NYC water taste better.
