General Description: When I program a 9500 device in iMPACT, the process fails to complete. (I am able to program other devices.)
The problem is with the number of attempts iMPACT makes when trying to program a 9500 cell. The normal operation of 9500 devices may require multiple attempts to program a particular cell; the current version of IMPACT only attempts to program a cell in the device twice before it goes to the next cell.
To work around this issue, you may also download the JTAG Programmer from WebPACK version 3.3 08i. (Please see (Xilinx Answer 12740) for information on obtaining JTAG Programmer.)
NOTE: Some older 9500 devices cannot be programmed with iMPACT -- specifically, any 9500 devices with a silicon version of 0000, 0001, or 0010. These devices will appear as "9500_unsupported" in iMPACT. Please see (Xilinx Answer 12737) for more information on unsupported 9500 devices.
