5.1i iMPACT, System ACE CF - When I attempt to program a JTAG chain containing a Virtex-II/Pro device, configuration fails (svf2ace)


General Description:

I cannot use the System ACE CF controller to program Virtex-II and Virtex-II Pro devices with ".ace" files generated by the following versions of iMPACT:

- 5.1i

- 5.1i/Service Pack 1

- 5.1i/Service Pack 2

- 5.1i/Service Pack 3

Programming the JTAG chain via the TSTJTAG port (bypassing the System ACE CF device) using any 5.1i version of iMPACT is successful.


5.1i iMPACT with Service Pack 3 is generating faulty .ace files due to an SVF file generation problem for Virtex-II and Virtex-II Pro devices (iMPACT automatically generates the .ace file from the .svf file using the svf2ace translator).

A patch is available on the Xilinx FTP site to correct this problem. This patch should only be used with 5.1i/Service Pack 3. Please view the archived README file for installation instructions:


The System ACE CF file generation problem is fixed in 5.2i iMPACT, which will be available in late February, 2003.
