We will be using one of the following devices : A5EC008BM16AI4S, A5EC013BM16AI4S or A5EC028BM16AI4S - and we will not be using smartVID ! For the CvP_CONFDONE I found a note in the Quartus software when defining the options for the "Configuration Pin Options" that if not used then "can be used as a user I/O" thus I assume it CAN BE left N/C. I couldn't find this info in the Intel Docs - which is a shame !

I still need to know about AS_nCSO3 pin, PWRMGT_SCL & PWRMGT_ALERT/SDA(this is a shared pin with SDM_IO12).

Hi,

 

AS_nCSO3 pin, PWRMGT_SCL & PWRMGT_ALERT/SDA pin can be left floating if it is unused.
