Filed: 1998-12-14
Abstract: PROBLEM TO BE SOLVED: To generate a high-speed memory IC test pattern, by using the N execution results of a pattern generation means and generating a digital data pattern. SOLUTION: For example, a computer 200 analyzes the execution of a program to generate an ALPG program for three units. Programs are loaded into each ALPG through a data carrier path 300. For example, programs in (a), (b), and (c) are loaded into ALPG100-1, ALPG100-2, and ALPG100-3, respectively. According to the execution of each ALPG program, ALPG for three units is outputted successively each time a clock 401 is inputted.
