Disabling serdes on ECP5UM-5G FPGAs to save power

Hey,

I’m developing an application using Lattice’s ECP5 evaluation board. I’m seeing significant power consumption (for my application) on the serdes power rails (VCCA, VCCA_SERDES).

I’m going to try just instantiating all of the serdes and putting them in standby, but I wonder if there are settings that would normally be configured via a Lattice tool.

Thanks!
John
