Abstract
Systems and techniques for fixing design requirement violations in a circuit design in multiple scenarios are described. During operation, a system can receive a scenario image and a multi-scenario ECO database. The scenario image can store parameter values for circuit objects in a scenario, and the multi-scenario ECO database can store a subset of parameter values for a subset of circuit objects in multiple scenarios. Next, the system can determine an engineering change order to fix one or more design requirement violations, which can involve estimating parameter values for circuit objects in multiple scenarios using parameter values stored in the scenario image and the multi-scenario ECO database.
