GROUP BASED ROUTING IN PROGRAMMABLE LOGIC DEVICE |
| 摘要 |
Various techniques are provided to route connections within a programmable logic device (PLD). In one example, a method includes determining timing slacks for connections described in a netlist for a programmable logic device (PLD). The method also includes determining a plurality of priority groups. The connections are associated with one or more of the priority groups based on the timing slacks. The method also includes routing the connections associated with each priority group, from a highest priority group to a lowest priority group. Each priority group is iteratively routed to remove routing conflicts before lower priority groups are routed. Additional methods, systems, machine-readable mediums, and other techniques are also provided. |

1. A computer-implemented method comprising:
determining timing slacks for connections described in a netlist for a programmable logic device (PLD); determining a plurality of priority groups, wherein the connections are associated with one or more of the priority groups based on the timing slacks; and routing the connections associated with each priority group, from a highest priority group to a lowest priority group, wherein each priority group is iteratively routed to remove routing conflicts before lower priority groups are routed. |
