Abstract: Systems and apparatus for an integrated test tool for that utilizes reconfigurable hardware to assess power delivery quality. In one aspect, a method includes receiving, at a control logic block in a field programmable gate array (FPGA), a load current amplitude value and a load current frequency value; determining, by the control logic block, an activation modulation signal that causes each of a plurality of load cells to which it is applied to be in an active state for a first period of time and in an inactive state during a second period of time, and a first of number of load cells that when activated according to the activation modulation signal cause the FPGA to draw a load current at the load current amplitude.
