GENERIC DESIGN RULE CHECKING (DRC) TEST CASE EXTRACTION

摘要

A computer-aided testing is provided for design verification of integrated circuits. More specifically, a method of generating a test case in design rule checking is provided for that includes extracting coordinates of an error marker for a first error identified in an integrated circuit design. The method further includes identifying a first rectangle that encloses the error marker. The method further includes generating a first test case based on data of the integrated circuit design contained within the rectangle. The method further includes determining whether the first test case is representative of the first error. The method further includes in response to determining the first test case is not representative of the first error, identifying a second rectangle that is between the first rectangle and a third rectangle. The method further includes generating a second test case based on data of the integrated circuit design contained within the second rectangle.

1. A method of generating a test case in design rule checking, comprising:
extracting coordinates of an error marker for a first error identified in an integrated circuit design; identifying a first rectangle that encloses the error marker; generating a first test case based on data of the integrated circuit design contained within the rectangle; determining whether the first test case is representative of the first error; in response to determining the first test case is not representative of the first error, identifying a second rectangle that is between the first rectangle and a third rectangle; and generating a second test case based on data of the integrated circuit design contained within the second rectangle.
