  • Method and system for routing optimally between terminals through intermediate vias in a circuit design
    Patent number: 8726222
    Abstract: A system and method are provided for establishing an automated routing environment in an electronic design automation (EDA) work flow for the routing of a circuit design. A user may merely specify a flow via pattern, a flow via location, and a start and end terminal and thereby, the auto router or path finder will automatically find the least-cost paths between each of the start terminals through at least one intermediate via of the flow via and ending at an end terminal. Upon successful routing of all needed terminals, an at least partially routed circuit design may be output.
    Type: Grant
