Abstract:
1. A method, comprising: a computer system storing, in a database, first and second values for a design parameter that specifies a physical layout property of an integrated circuit, wherein the first and second values are respectively based on first and second parameter settings for first and second different electronic circuit design tools; receiving a request to the database for the design parameter, wherein the database includes a plurality of sections, each of which specifies a type of physical layout data, and wherein the plurality of sections include first and second sections that respectively store the first and second values for the design parameter; the computer system generating a response to the request based on a combination of the first and second values for the design parameter, wherein the generating includes calculating a total confidence value for the design parameter that is based on first and second confidence values that respectively correspond to the first and second values for the design parameter; and the computer system returning the response to the request, wherein the response indicates, based on whether the total confidence value exceeds a confidence threshold value, whether an error condition exists for the design parameter.
