Abstract
A system and method for correcting connectivity errors in a mask layout are disclosed. The method includes comparing a first connection in a mask layout file to a second connection in a schematic netlist. A connectivity error is identified if the first connection does not match the second connection and the identified connectivity error is automatically corrected in the mask layout file.
Claims22
An automated method for correcting connectivity errors in a mask layout file, comprising:
- comparing a first connection in a mask layout file to a second connection in a schematic netlist;
- identifying a connectivity error in the mask layout file if the first connection does not match the second connection;
- and
- automatically correcting the connectivity error in the mask layout file.
A computer system for correcting connectivity errors in a mask file, comprising:
- a processing resource;
- a computer readable memory;
- and
- processing instructions encoded in the computer readable memory, the processing instructions, when executed by the processing resource, operable to perform operations comprising:
- comparing a first connection in a mask layout file to a second connection in a schematic netlist;
- identifying a connectivity error in the mask layout file if the first connection does not match the second connection;
- and
- automatically correcting the connectivity error in the mask layout file.
Software for correcting connectivity errors in a mask layout file, the software being embodied in computer-readable media and when executed operable to:
- compare a first connection in a mask layout file to a second connection in a schematic netlist;
- identify a connectivity error in the mask layout file if the first connection does not match the second connection;
- and
- automatically in response to identifying the connectivity error, correct the connectivity error in the mask layout file.
