Is there an analog version of caravel for GF180MCU?

Not yet, but it is planned to be available soon.

Great 👍🏻

As soon as I figure out what to do about the pads, which don't have a GPIO with an analog option. The number of analog pins may be more limited than on sky130, or maybe I can come up with a scheme that lets some GPIO pads be swapped out completely for analog pads.
