Abstract
The present invention provides a method for performing design rule check (DRC) of an integrated circuit. A design layout of the integrated circuit is provided. The integrated circuit includes a complex circuit. A DRC tool is used to compare a portion of the design layout with a reference layout containing an accurate implementation of the complex circuit. The portion of the design layout corresponds to the complex circuit.
Claims17
A method for performing design rule check (DRC) of an integrated circuit, comprising:
- providing a design layout of said integrated circuit, said integrated circuit including a complex circuit;
- checking, by a DRC tool, a first portion of said design layout against a set of design rules to check said first portion of said design layout, said first portion of said design layout not including said complex circuit;
- and
- comparing, by the DRC tool, a second portion of said design layout, which has not been checked against the set of design rules, with a reference layout containing an accurate implementation of said complex circuit, said second portion of said design layout corresponding to said complex circuit.
A computer-readable medium having computer-executable instructions for implementing a method for performing design rule check (DRC) of an integrated circuit, said method comprising:
- providing a design layout of said integrated circuit, said integrated circuit including a complex circuit;
- checking, by a DRC tool, a first portion of said design layout against a set of design rules to check said first portion of said design layout, said first portion of said design layout not including said complex circuit;
- and
- comparing, by the DRC tool, a second portion of said design layout, which has not been checked against the set of design rules, with a reference layout containing an accurate implementation of said complex circuit, said second portion of said design layout corresponding to said complex circuit.
A system for performing design rule check (DRC) of an integrated circuit, comprising:
- means for providing a design layout of said integrated circuit, said integrated circuit including a complex circuit;
- checking, by a DRC tool, a first portion of said design layout against a set of design rules to check said first portion of said design layout, said first portion of said design layout not including said complex circuit;
- and
- means for comparing, by the DRC tool, a second portion of said design layout, which has not been checked against the set of design rules, with a reference layout containing an accurate implementation of said complex circuit, said second portion of said design layout corresponding to said complex circuit.
