I am working on a old design based onXc3195 which is using XC17128 as configuration PROM.
I may have to extract an existing design (mcs file the existing XC17128 board)and program a new device in a new board.
Pl. guide me how to do this and reg. the tools required?

Just to clarify - are you programming an identical board with this file? That is, it's still an XC3195 and and XC17128, they're just not programmed yet?
That should be fairly straightforward, although you'll have to desolder the chip (doesn't appear to be in-circuit programmable, you have to stick it in a PROM programmer and read the data off it).
If you're programming a different device in a different board (eg. upgrading to a Spartan 7) then the answer is "restart the design from whatever documentation you have available". There is zero compatibility between different FPGAs, and also no tool that can move a design between FPGAs (I expect that Xilinx can do it in some very limited cases, but they're not going to tell anyone else how to do it).

Thanks for the reaply.
Yes. I have to use in an identical board only with XC3195 and XC17128.
The PROM is EPROm and not insystem programmable.
Pl. suggest me any programmer tool for the same.

You have multiple problems to solve here,
First you need to de solder the XC17128 without damaging it.
If you can then you can connect that to the new board
Are you trying to copy the PROM to make multiple boards ?
Then your problem is, do you own the copyright for that design ?
If you dont, then please do not ask us to help you break the law,
( rember most of us on here make our money designing and selling boards )

re programming tool
this is a cheap one
