Group based routing in programmable logic device

A system comprising:

• a processor;
• and
• a memory adapted to store a plurality of computer readable instructions which when executed by the processor are adapted to cause the system to perform 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.

A non-transitory machine-readable medium storing a plurality of machine-readable instructions which when executed by one or more processors of a computer system are adapted to cause the computer system to perform 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.
