Hi, In 6x10 WLCSP, Pin description for vdda1 is 3.3V. In ChipIgnit, can Vdda1 be equal to 1.8V? Thanks

The description reflects the properties of the development board that we ship with projects, which has a 3.3V regulator on it. But the SkyWater documentation for the I/O cells states that the I/O will work with any voltage from 1.8V to 5.5V. So yes, you can set your VDDA1 to 1.8V.
