Abstract: A method for implementing physical optimizations includes performing physical optimizations on a first reference version of a design, maintaining a computer-readable list of the physical optimizations, and during a subsequent compile for a second version of the design: identifying matching cells, nets, or both between the first reference version of the design and the second version of the design; and restoring at least a subset of the physical optimizations in the second version of the design by reading the computer-readable list of the physical optimizations and applying the subset to a computer-readable description of the second version of the design.

Abstract: A method for designing a system on a target device utilizing programmable logic devices (PLDs) includes generating options for utilizing resources on the PLDs in response to user specified constraints. The options for utilizing the resources on the PLDs are refined independent of the user specified constraints.

Abstract: A method for designing a system on a target device includes merging a netlist for a first partition of the system generated from a bottom-up design flow with a netlist for a second partition of the system from a top-down design flow to form a combined netlist, and performing fitting on the combined netlist.

Abstract: A method for designing a system on a target device includes generating a first netlist for a first version of the system after performing synthesis in a first compilation. Optimizations are performed on the first version of the system during placement and routing in the first compilation resulting in a second netlist. A third netlist is generated for a second version of the system after performing synthesis in a second compilation. A hybrid netlist is generated from the first, second, and third netlists. Incremental placement and routing are performed on portions of the hybrid netlist that are new to the first compilation.
