I am curios if there is a relatively simple modification I can do to increase available FPGA power, especially the 1V into the FPGA, on a Z7-20 board?
Background, my problem is simple. I load a design into the Zynq that is expected to drain much more on the 1V supply then what the PMU inside the board can deliver, when loaded the LD13 led goes down almost instantly indicating that the supply rails can't keep up. This is easy to do, just try to use half of the Fabric at a decent frequency (200+MHz) and you will have run out of power. So I assume the PMU was dimensioned for the smaller FPGA on Z7-10 originally.
