conversion from Virtex-5 to Virtex-II pro compatible code

[nat283]

Hey

How do you convert a code that is compatible with Virtex-5 to one that is compatible with Virtex-II Pro?

Thanks.

The compiler generates the hardware specific code (bitfile).

If you speak about LV code there's no difference in the sources.

Bitfiles can't be converted easily.

Well if I am correct, the Virtex 5 has a lot more resources available than the Virtex-II.  If you have a lot of code on your Virtex-5 you may not be able to port the code backwards.  Also if you are using more than 3 DMAs, you'll need to make significant changes.  The 5 series has 16 DMA channels (16 host-target FIFO or Target-Host FIFOs) whereas the II series has only 3.
