Automated assisted circuit validation
A method comprising categorizing nodes of a fabricated circuit as being priority nodes and nodes as being inferior nodes; evaluating a first priority node by automatically designating for verification the first priority node, and ascertaining whether a measured signal from the first priority node meets a pass-fail criterion for the first priority node; evaluating, when the measured signal from the first priority node meets the pass-fail criterion, a second priority node by automatically designating for verification the second priority node, and ascertaining whether a measured signal from the second priority node meets a pass-fail criterion for the second priority node; and evaluating, when the measured signal from the first priority node does not meet the pass-fail criterion, a first inferior node, by automatically designating for verification the first inferior node, and ascertaining whether a measured signal from the first inferior node meets a pass-fail criterion for the first inferior node.

APPARATUS AND METHOD FOR MAPPING FOUNDATIONAL COMPONENTS DURING DESIGN PORTING FROM ONE PROCESS TECHNOLOGY TO ANOTHER PROCESS TECHNOLOGY
A method and system for migrating an existing ASIC design from one semiconductor fabrication process to another are disclosed herein. In some embodiments, a method for migrating the existing ASIC design comprises parsing the gate-level netlist one row at a time into one or more standard cells forming the ASIC design, forming a plurality of mapping tables having mapping rules for mapping the parsed one or more standard cells into equivalent target standard cells implemented in the second semiconductor fabrication process, mapping the parsed one or more standard cells into the equivalent target standard cells using the plurality of mapping tables, and generating a target gate-level netlist describing the ASIC design in terms of the equivalent target standard cells.

Encoding and Decoding Variable Length Instructions
Methods of encoding and decoding are described which use a variable number of instruction words to encode instructions from an instruction set, such that different instructions within the instruction set may be encoded using different numbers of instruction words. To encode an instruction, the bits within the instruction are re-ordered and formed into instruction words based upon their variance as determined using empirical or simulation data. The bits in the instruction words are compared to corresponding predicted values and some or all of the instruction words that match the predicted values are omitted from the encoded instruction.
METHOD AND APPARATUS FOR CHECKING SCHEMATIC CIRCUIT DIAGRAM AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM
