Abstract
Timing verification of the LSI test data is performed as follows. In test synthesis, a script text for static timing analysis (STA) is generated together with a test circuit. The STA script text is used to perform static timing analysis. Function verification is performed between a netlist generated through the test synthesis and a timing-verified netlist based on the static timing analysis. The function-verified netlist is released to a production division, and the netlist is used to automatically generate a test pattern by an automatic test pattern generation (ATPG) tool. A netlist comprising test vectors for automatic test equipment is acquired from the generated ATPG pattern.
