8.2i SP3 XST - Unable to generate cores in CORE Generator, or the core netlist is empty


I am unable to generate the following cores in ISE 8.2i sp3, or the core netlist generated is empty:

- FIR compiler V 1.0

- DVB S2 Encoder

- DA FIR V 9.0

- MAC FIR V 5.1

- FIFO Generator V 2.3


This issue is fixed in ISE 9.1i. The fix is also available with the LXT patch for ISE 8.2i from the Download Center:


Xilinx highly recommends that you download this patch, even if you are not going to be using one of the above cores.
