Abstract

See full text

Various techniques for referencing components of a programmable logic device (PLD) are provided. In one example, a method of referencing wires of a routing graph of a PLD is provided. The routing graph comprises a plurality of routing graph wires and a plurality of routing graph switches corresponding to components of the PLD. The method includes maintaining a plurality of master tiles comprising a plurality of master wires and a plurality of master switches corresponding to the routing graph wires and the routing graph switches, respectively. The method also includes identifying a first one of the routing graph wires. The method further includes mapping the first routing graph wire to a second one of the routing graph wires using at least one of the master wires.
