When I attempt to create an XSVF file for a JTAG chain containing a Spartan-3AN device in the chain, I cannot create the XSVF file.
Is there a way to work around this issue?
The XSVF flow is not supported for the Spartan-3AN family so when a Spartan-3AN is in the chain, iMPACT will not allow XSVF generation.
If you need to generate an XSVF to target devices in a JTAG chain containing Spartan-3AN devices, to work around this issue, you can add the equivalent Spartan-3A BSDL file to the chain. The IDCODEs and instruction length registers match for equivalent density Spartan-3A and Spartan-3AN devices, which will allow you to generate correct XSVF files.
This issue will be resolved in the iMPACT 11.1 release.
