reduce EDK synthesis time

[catto]

Hello,
i'm working on microblaze project (using ISE 10.1) and obviously addin
peripheral the EDK synthesis takes a long time.
There's a method or tool to improve this time??
I've tried the -smartguide switch but it doesn't work, i'm trying usin
partitionďťż. Have you any regard?
Sorry for my english i'm foreign.

ISE 13.1 is much faster than ISE 10.1 so if you're starting a new
design you might consider using ISE 13.1 Furthermore, Xilinx has
improved EDK a lot.

I would say that for synthesis in general, the speedup is about 2x
between version 10.1 and 13.1

EDK 13.2 now also adds support for parallel synthesis, which can give a
big speed up if your computer has more than one CPU.
You can enable it from:

XPS->Preferences->Synthesis->[x]Parallel Synthesis

Nice feature

Echoing what others have said. You should really use versions greater tha
11.4. This is because Xilinx changed a lot of the backend algorithms. IS
is now noticeably faster than <11.4.
