any specific reason as logic analyzer port size reduced to 64 bit for GF180 design, as sky130 default size is 128 bit? @Tim Edwards

no, I hadn't noticed it

Yes; Sky130 is 0.13um. GF IP is all 5V-rated so the minimum transistor length is 0.5um, making it effectively a 0.5um processs. Area-wise, we can get about 1/4 the amount of circuitry in the same area relative to Sky130 (It would be worse, but we have SRAM blocks which take up much less area than the equivalent DFFRAM that we were using on Sky130). Something had to give.
