solve this one????

you need to open a WebCase, and wait for their response. nothing more you can do, its a fatal error.

xilinx internal software error. nothing you can do, just call Xilinx and hope for the best...

but sometimes you can have a temporary "work-around", like disabling flattening hierarchy or timing-driven packing, etc... until a new SP comes out

Hi John

I already came across with this kind of error before (ISE 6.3), which appeared just after entering the "HDL Analysis" task (second step performed by XST after "HDL Compilation").

After spending a fair amount of time trying to isolate what triggers this error, I found out that it was a mismatch between a port declaration in an entity, and the port declaration of the related component in the upper level of the hierarchy (in a VHDL design).

Therefore my advice will be to try to compile your design with an other parser/compiler (such as Modelsim, who seems more strict than XST), and make sure that no suspicious warnings remain.
