Loaded an FPGA bitstream that instantiates the QSGMII transceivers on the FPGA.

Power consumption climbed to 12.7W and the FPGA die temperature is up to 48.5C.

The 1V0 rail for the GTXes is sagging to 975.5 mV under load, since it's just pi filtered off of the main FPGA 1V0 rail without an independent remote sense. This is within spec... barely. But definitely something I will want to work on in the future. The full LATENTRED switch (with eight transceivers) will definitely need a dedicated SERDES power rail with independent regulation.

The FPGA 1V0 rail is doing just fine, 1.0015V at the test point and 0.996V measured by the on die ADC.
