摘要
Local constraints on placement of routing objects for direct connections between terminals in a circuit layout are determined from global constraints on the placement of the routing objects in a process referred to as global constraint budgeting. An autorouter finds paths in the layout to satisfy the local constraints and ignores the global constraints. The local constraints are updated before each routing pass to ensure that routes are completed on individual direct connections while also satisfying the global constraint.
