The characterization of semiconductor integrated circuits using standard bench equipment is optimized using software reconfigurable interface boards. A field programmable gate array (FPGA) provides reconfigurable virtual instruments and traditional instrument control and signal routing via a matrix relay board. An FPGA including a power PC processor core is programmable in C/C++ with the automated test procedure while maintaining a fixed logic for the gate array used to support a minimal amount of external circuitry needed to provide testing resources. The test capabilities of a traditional bench can be expanded to include protocol aware testing and supplemental test circuitry implementation including over temperature testing.
