Looks awesome.

So what is on it ?

This could be a digital art 😄.

That's amazing!!!

Masterpiece.

- rv32ima_zicsr core in 6502-compatible pinout
- 6502/6510 clone (cycle-accurate, now hopefully with the bus timing fixed)
- C64 PLA
- Nanoprocessor clone, 8-bit educational CPU, LED blinker
- The two [FeatherLane](https://codeberg.org/TholinVali/FeatherLane) -generated layouts: rv32i core and a VERY simple CPU that is a 32-bit version of [MCPU](https://github.com/cpldcpu/MCPU/tree/master) 
- C64 SID clone
- C64 SID clone, but I added FM synthesis features on top (fully backwards-compatible)
- General-purpose IO peripheral block you can hook up to an existing CPU
- Test NTSC signal generator (now in color - I have it set up displaying some pixel art or pride flags)
- The R2R DACs (hopefully the output stage isn’t power hungry anymore)
- Another copy of 32-bit MCPU, except its using Dynamic DFFs (we’ll see how that works out on this process node)
- The Palette, which contains samples of everything I can draw and experiments with metal spacing - will give microscope images of this to any artists that agree to create silicon art for me in the future, to give them more options for "colors"

The Dynamic DFF MCPU hits an fmax of 125MHz on the typical corner. The Dynamic DFFs would be such an upgrade, if they end up working.

You are my hero now. @Tholin
