3.3i Foundation ISE Project Importer - Incorrect handling of BUFG on schematic source files


Keywords: ISE, Project Importer, Aldec

Urgency: Standard

General Description:
Synopsys will not insert pads in front of BUFG symbols for 4K-derived devices.
As a result, 4K families will error out in MAP.


For 4K, Spartan, or Spartan XL designs, modify the schematic by inserting an
IBUF between the IPAD and the BUFG. This will allow the implementation tools
to complete. However, the dedicated clock path will not be used, and timing
could be affected.
