I've not really pushed the buffer board at all, have not had a heatsink on it until today. Xilinx XCKU5P docs specify a 52 amp maximum for VCCINT with the FFVB676 package. I'm taking that as a challenge, this board is capable of 80 A.

A bunch of my AES cores to use up the LUTs and FFs, my cosine cores to use the DSPs and BRAMs will do a good job of loading all of the resources for power testing. I'll be doing load step in addition to maximum power testing.
