ISE 9.2i design tools build on capabilities of ISE Fmax Technology, especially designed to deliver unparalleled performance and timing closure results for high density, high performance Virtex-5 based designs. The ISE 9.2i integrated timing closure flow incorporates enhanced physical synthesis optimizations that provide optimal clock placement, better packing, and timing-driven mapping for higher quality of results. 4 a9 p8 d1 t. x' ~) ]1 q4 [

Underlying the entire ISE 9.2i infrastructure is an expanded timing closure environment – a virtual “Timing Closure Cockpit” – that enables seamless cross-probing between constraint entry, timing analysis, floorplanning and report views so designers can more easily analyze timing problems. 9 h8 g3 I% @!

+ F2 d9 A8 k* ]Partitions deliver guaranteed preservation of existing implementation. Users can define Partitions, or hierarchical blocks, within their design. They can then specify that the synthesis, placement, and/or routing of these partitions are to be preserved during re-implementation. + [: n% c! G5 Y2 y# V$ A+ b" D* U
SmartGuide minimizes implementation differences between two versions of the same design. SmartGuide is available from the ISE Project Navigator and does not require substantial changes to an existing design flow. Faster runtimes will be realized and timing preserved for small design changes that are not on a critical path.
8 g% \9 i5 Y+ _ z& |' @& ASmartPreview allows users to pause and resume implementation. This allows the user to save intermediate results, view state of design (paths that fail timing, routing status), generate bitstreams, and perform timing analysis. This reduces the impact of long implementation cycles by providing insight into the implementation process.

Integrated Timing Closure Environment: The Integrated Timing Closure Environment has provides a virtual timing-closure cockpit. This integration of PACE, the timing analyzer, constraints editor, and the floorplanner view allows cross probing between those views and the ISE Design Summary. This allows users to explore their design and address problems from multiple angles. The Integrated Timing Closure Environment is available for Virtex-5, Virtex-4, and Spartan™-3A devices. * ^; R# ]" m5 }5 k# v3 ? g
