PROBLEM TO BE SOLVED: To provide an inspection signal generator for suppressing man-hours for design from increasing and that can be operated at a high frequency. SOLUTION: The inspection signal generator 10 includes a pattern generating section 20, including a calculation controlling section 21 for generating calculation control signals CS1, CS2 from pattern address control signals C11, C12 based on a predetermined rule, and pattern address calculators 22a, 22b for generating addresses A22a, A22b by using an address A23b output from a pattern address register 23b, based on the calculation controlling signals CS1, CS2. The pattern generating section 20 is operated and synchronized with a clock signal CLK, whose frequency is half the frequency of an inspection signal S10. COPYRIGHT: (C)2007,JPO&INPIT
