List of sub-projects and status (alphabetical)

Device/Vendor	Status	Note
Cypress PSoC 5(LP)/4/3	Not yet started	Other than the UDB routing fabric and the DSI, everything is publicly documented.
Silego Greenpak 4/5	Can go from HDL to bitstream for most digital functions and some analog of SLG46620V	Bitstream is publicly documented
Xilinx CoolRunner-II	Everything understood for XC2C32A, larger devices missing ZIA table, working place-and-route	Needs a lot more bug testing
Xilinx 7 series	Wishlist, no actual work done

Collected Research
