ELECTRA is a new generation of Shape-Based Autorouting software for PC boards. By contrast with traditional gridded maze autorouters, a shape-based approach allows for more efficient use of routing area and is more suited to handle complex design rules requirements of high density SMD or through holes boards and achieve the highest route completion rates. ELECTRA is designed to plug into an existing PCB CAD system environment that is supporting DSN file format such as Protel, P-CAD and other popular CAD systems including Cadsoft Eagle.
