Abstract:
1. A computer-executed method to manage violations during physical verification, the method comprising: identifying, by computer, a first design-rule-check (DRC) violation by applying a set of DRC rules to a layout; presenting the first DRC-violation to a first user; receiving a first error-classification from the first user, wherein the first error-classification specifies how the first DRC-violation is to be handled, and wherein the first user is not authorized to approve error classifications; storing, in a database, the first DRC-violation, the first error-classification, and a user identifier associated with the first user, wherein the database associates the first DRC-violation with the first error-classification and the user identifier, and wherein the database indicates that the first error-classification has not been approved; presenting the first DRC-violation, the first error-classification, and the user identifier to a second user who is authorized to approve error classifications; and in response to receiving input from the second user which indicates that the second user approves the first error-classification, modifying the database so that the database indicates that the first error-classification has been approved.
