Abstract
A system, a computer program product, and a computer-implemented method are provided for automatically generating a LVS rule file, and/or for automatically generating a regression test data suite.
Claims21
A method, comprising:
- in a processor in a computer, performing operations for:
- processing a design rule manual (DRM) document to generate a data structure that corresponds to the DRM document, wherein the data structure comprises an entry for each particular device, wherein each entry specifies one or more prohibited layers and one or more required layers for that particular device;
- and
- automatically generating, based on the entries for each particular device in the data structure, a LVS rule file.
1 more element
A computer program product for use with a computer, the computer program product comprising a non-transitory computer-readable storage medium comprising computer-executable instructions stored thereon, the computer-executable instructions performing steps comprising:
- processing a design rule manual (DRM) document to generate a data structure that corresponds to the DRM document, wherein the data structure comprises:
- a list of all layers of an integrated circuit that is specified by the DRM document, a list of all devices of the integrated circuit that are specified by the DRM document, and an entry for each particular device, wherein each entry specifies a list of all prohibited layers for each particular device, and a list of all required layers for each particular device;
- and
- automatically generating, based on the entries for each particular device in the data structure, a Layout Versus Schematic (LVS) rule file.
1 more element
A system for performing electronic design automation tasks, the system comprising:
- a computer processor;
- a storage memory coupled to said computer processor;
- an input apparatus for inputting a design rule manual (DRM) document;
- and
- a computer program configured to include software modules including:
- a parsing module configured to processes the DRM document to generate a data structure that comprises:
- a list of all layers of an integrated circuit that is specified by the DRM document, a list of all devices of the integrated circuit that are specified by the DRM document, and an entry for each particular device, wherein each entry specifies a list of all prohibited layers for each particular device, and a list of all required layers for each particular device;
- and
- a Layout Versus Schematic (LVS) rule file generator module configured to automatically generate, based on the entries for each particular device in the data structure, a LVS rule file.
