US 8,302,041 B1 · Implementation flow for electronic circuit designs using choice networks

Abstract

A computer-implemented method of implementing a circuit design that includes an initial network within a programmable logic device can include generating a first choice network from the circuit design according to a first synthesis technique and determining a placement for the first choice network. At least a second choice network can be generated from the first choice network according to a second synthesis technique. A placement for the second choice network can be determined. The placement for the first choice network can be compared with the placement for the second choice network. A placement and corresponding choice network can be selected according to the comparison, and output.
