I am working with Spartan 6 (XC6SLX4) FPGA. I am trying to program it using Xilinx 14.2 ISE, the project was succesfully build and prografile was also generated without any error. But; when I configured Hardware by entering into ISE impact; this gave me error as follows:
"error bitstream:14- The device part "6slx4tqg144" specified in bitstreamfile "E:/Amit/FPGA IV/code/Spartan6trial/ucf.bit" is invalid. The file may be corrupted and should be recreated."
Its image is attached with this query. Can anyone help me for this issue
thank you in advance.

what OS you using ?
is this the web pack licence ?
if you can I'd update to the last ISE 14.7

Thank you for replying,
I am using Win XP(SP2) and programming FPGA using parallel port.
can you please explain me how changing from ISE14.2 to 14.7 will help me to resolve my errors? i am more interested in analyzing this. Apart from this it is mentioned in ISE design Suite release note about compatibility of Spartan 6 (XC6SLX4) with ISE14.2; therefore I used it.
Also can you suggest me what else configuration/ JTAG cable will work with my PC OS and webpack version, just like Platform cable USB?

currently what programming cable are you using?
Win XP which edition? professional or home edition?
before assigning the bit file can you do the jtag scan of the board? can you share the .log file instead of image?

You wonder why we ask abotu the ISE version, and suggest updating.
The 14.7 is the last ISE,
and the only one that is maintained to any level,
so its the ISE that has the most bugs fixed,
there seems little reason to keep with an older version,
14.7 is also the version I have,
If you want to stay on 14.2, thats fine, I can see why a big project would not want to update
bu **bleep** harder for us to help,
You could start by looking at all the answer / fix records from 14.2 to 147 , see if this is a know bug,
or just move to 14.7
The parallel cables are EOL , a long time back,
can you just check that ISE is compatible with the OS you have,
The parallel port always had problems with the anti virus etc checking software,
as the programmer had to toggle the pins "behind" the OS.
which good protection systems try to block, kind of a catch 22 situation.
You ask about other programmers
All recent programmers are USB or Ethernet.
