13. A semiconductor device testing system, which comprises:
a burn-in oven adapted to receive a plurality of devices;
a flexible service processor, said flexible service processor being configured to generate device test input signals and receive device test output signals, said flexible service processor being further configured to generate test select signals and voltage control signals;
a test multiplexer connected to receive device test signals from said flexible service processor and supply device test output signals to said flexible service processor, said test multiplexer being configured to multiplex said device test signals to selected devices in said burn-in oven under control of said test select signals at selected voltages under control of said voltage control signals, said test multiplexer being further configured to receive device test output signals from said devices and selectively provide device test output signals from selected devices under control of said test select signals.
