Recently the CEO and founder of ProGrAnalog, Roger Beeton, took part in a webinar hosted by ElectronicDesign.com: How to properly test a high current FPGA power distribution network.

The webinar reviewed how testing real world regulator performance, under normal and worst-case operating conditions with a LoadSlammer Xilinx Versal AI FFED Test System, is the optimal way is to verify power delivery performance. They also reviewed and explained the various tests the FFED solution provides including: OCP, transient, 3DSweep and Large output Impedance.  

Although the performance per watt is best in class, the need for higher supply currents, higher current load steps, lower voltages and tighter regulation requirements is even greater. The design challenge is to eliminate non linearities and resonances in the power delivery scheme whilst keeping tight tolerances.
