Optimized routing algorithms provide the most efficient utilization of the diagonally symmetric interconnect of the 65nm ExpressFabric™ to minimize delay and fully leverage the high performance features of the Virtex-5 Platform. ISE 9.2i routing algorithms also support pin swapping based on timing requirements to further maximize design performance & R; ~/ @  \% I  B9 d

Introducing new SmartCompile Technology2 h0 r& m0 c+ r0 ?8 A- p1 P$ g
Improvements in the mapping, placement, and routing algorithms allow users to realize an average of 2.5X faster compile times, for tough designs. This allows users to get more implementations, or turns, of their designs enabling faster time-to-market and less frustration. 7 G. W* k, L$ T/ M, X- [" T! N7 Y1 M

FPGA designers can realize an additional 2.5X faster runtimes, on average, with SmartCompile Technology in ISE 9.2i with some designs achieving up to 6X faster runtimes for incremental changes.
1 z7 b$ T0 |- Q9 z4 i' w& |8 F3 ~' k! E9 `
SmartCompile is comprised of three new features; SmartGuide, Partitions, and SmartPreview.
7 `. T* q; B4 o# }. L2 D9 Y! w) ^' x$ T8 \( U
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.
- Y2 e( E4 Y: H7 M: kSmartGuide 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.
+ Z3 }  E9 e2 K, a% {8 SSmartPreview 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.

Tcl Command Window: The Tcl window allows users to easily navigate between the ISE graphical environment and the command line.

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. % Q! y* ]- j( S0 `' u; Z' H" m

講了這麼多, 我覺得4 e3 ]3 v) B1 a# t" W; ~) O
% U5 x4 T! v) Y4 _) E! Z
1) ise9.2 把ise9.1的功能加上3個service pack合在一起了' N8 A) I/ R7 \: X6 D7 t
2) smart guide 跟 smart complier在9.1就有了, 我個人覺得很好用, 沒用過的人可以試試
, y8 S% I# ^! M  M* c3) 在時序收歛上, 我一直沒遇到這個問題, 有人有遇到解決不了的嗎?  F! V; G! L9 \5 b! j7 B
4) 我建議用dual core的電腦去compiler會快很多1 q3 d8 R" y) z# w
5) 在時序有問題時, 不妨試試floor planer跟FPGA editor這二套都內建在ISE內
$ c3 `' M& `& u/ |: A+ H# r

ISE有內建MIG (有人不知道MIG的嗎?)# S8 N9 R2 o8 @8 |8 _! l
在過去 ise9.1要安裝 service pack2才能執行MPMC2; 要裝service pack1才能支援3ADSP8 {- k' x6 z: B& |
