3.1i, Virtex-II - Instantiating OBUFDS_LVPECL_33 does not work in Xilinx tools

説明

Keywords: Virtex-II, LVPECL, LVPECL_33, NGDBuild, unexpanded, 432, output, OBUFDS

Urgency: Hot

General Description:
When instantiating an OBUFDS_LVPECL_33 in HDL code, I receive an NGDBuild error indicating that the component is unexpanded:

"ERROR:NgdBuild:432 - logical block 'OBUFDS_1' with type 'OBUFDS_LVPECL' is unexpanded."

This problem exists only for outputs; inputs instantiated in the same way work successfully.

ソリューション

This configuration is currently not supported in the current software; it will be fixed in the next major software release, which is due out in August, 2001.

A current work-around to this problem is described in (Xilinx Solution 11322).
