20. A tester system comprising:
a system controller communicatively coupled to a tester processor, wherein said system controller is operable to control a test program;
an instantiated FPGA block communicatively coupled to said tester processor, wherein said instantiated FPGA block comprises:
a reconfigurable protocol engine circuit operable to communicate with a DUT using a high speed communication protocol particular to said DUT; and
a packet builder circuit operable to generate packets comprising commands and data for running test operations on said DUT, wherein said DUT is coupled to said instantiated FPGA block, and further wherein said packets are communicated to said DUT using said high speed communication protocol,
wherein said reconfigurable protocol engine circuit and said packet builder circuit are programmed onto said instantiated FPGA block using said tester processor.
