  • Automatic test pattern generation system for programmable logic devices
    Patent number: 8516322
    Abstract: A programmable integrated circuit may contain multiple logic blocks. Computing equipment may be used to run automated tools that process a design for the programmable integrated circuit to perform corresponding circuit tests. A translation tool may translate a transistor-level description of circuitry on the programmable integrated circuit into a gate-level description. A block-level test configuration data generation tool may generate block-level test configuration data files. The test configuration data files may be used as constraints for an automatic test pattern generation tool that produces block-level test vectors. A full-chip propagation tool may use the block-level test vectors, block-level test configuration data files, and full-chip constraints to produce corresponding full-chip test configuration data and full-chip test vectors for testing the integrated circuit. A translation tool may convert the configuration data and test vectors into a tester file.
