Abstract
There are provided a test apparatus and method for testing a semiconductor integrated circuit which enables improvements in the ease of operation and convenience of a BOST device and shortening of a test time. Numeric codes are assigned to tests. A test apparatus is equipped with memory and an analysis section. A test requirement table—in which hardware requirements required for conducting a test are set on a per-numeric-code basis—is stored in the memory. Test requirements corresponding to a numeric code are read from the memory, whereupon a test is performed. The analysis section analyzes a digital test output and sends the result of analysis to an external controller.
