Abstract

Automated analyzing of an endpoint report for a design of an electronic circuit is provided, which includes: identifying, by a processing device, that one or more test points of a selected path of the endpoint report are associated with one or more inverter devices of an inverter chain of the design of the electronic circuit; establishing, by the processing device, a chain criticality value for the inverter chain; and determining, by the processing device, whether to identify the inverter chain as a dispensable inverter chain, the determining using, at least in part, the chain criticality value for the inverter chain. The establishing may include updating the chain criticality value for each inverter device of the inverter chain, where the chain criticality value is a summed value obtained from criticality values for the one or more inverter devices of the inverter chain.
