1. A method for checking circuit routing, comprising:
- a) accessing actual topology layout information of a circuit, wherein said actual topology layout information is in a vector format that is derived from a topology of said circuit;
b) establishing compliance topology information, wherein said compliance topology information is based on custom design information that describes basic information of said circuit;
c) checking said actual topology layout information complies with said compliance topology information; and
d) presenting violations of said compliance topology information.

Abstract
A method and apparatus for checking topology layout routing is described. A method for checking topology layout routing includes accessing actual topology layout information of a circuit. Then, compliance topology information is established. Then, the method checks the actual topology layout information complies with the compliance topology information. Then, the method presents violations of the compliance topology information.
