I am using a CY8C5468 in a new design, but I am not using any analog blocks in the device. What would happen if I left VDDA, VSSA, VCCA floating?
Many thanks

Since no voltage in a PSoC4 design may be larger than VDDA you will have to connect that at least. So VSSA must be connected too. I do not know whether the other two MUST be connected, but I've never seen a design where those were left floating.
