CIRCUIT INFORMATION PROCESSING DEVICE, CIRCUIT INFORMATION PROCESSING SYSTEM, DATABASE, NON-TRANSITORY COMPUTER READABLE MEDIUM, AND CIRCUIT DESIGN METHOD

A circuit information processing device includes an evaluating unit that evaluates complexity of placement and routing of each of multiple circuit configurations, the multiple circuit configurations each having a common portion common to the multiple circuit configurations and a non-common portion not common to the multiple circuit configurations, a selecting unit that selects, from among the multiple circuit configurations, a reference circuit configuration evaluated by the evaluating unit as satisfying a predetermined criterion, and a generating unit that causes first placement and routing information to be shared by circuit configurations other than the reference circuit configuration, and generates second placement and routing information for each of the circuit configurations other than the reference circuit configuration, the first placement and routing information being information for placing and routing the common portion of the reference circuit configuration, the second placement and routing information being information for placing and routing the non-common portion.
