A software structure in a semiconductor test system for easily modifying and transferring data for controlling a hardware when the hardware is changed or replaced. The semiconductor test system includes, an input for providing a test program for specifying various test conditions necessary to test the semiconductor device under test, a master processor for converting the test program to an object code and interpreting the contents of the test program, a processor interface for storing data indicating the hardware characteristics of the semiconductor test system in a table format to assist the interpretation of the test program in the master processor and modifying the table format data in response to the change in the hardware, a library having data tables based on the specification of the semiconductor test system for converting the format of the data compiled and interpreted by the master processor to data of a hardware format, and a driver for transmitting the hardware format data to registers in the hardware of the semiconductor test system through a data bus.
