7.1i Schematic - "ERROR:NgdBuild:604 - STARTBUF_SPARTAN3E could not be resolved..." for schematic design

Description

Keywords: schematic, startbuf, Spartan-3E, Spartan3E, spartan3e, translate, logical block

Urgency: Standard

General Description:
NGDBUILD (translate) fails on a Spartan-3E schematic design with the following error about the startbuf_spartan3e symbol:


ERROR:NgdBuild:604 - logical block 'XLXI_<#>' with type 'STARTBUF_SPARTAN3E' could
not be resolved. A pin name misspelling can cause this, a missing edif or ngc
file, or the misspelling of a type name. Symbol 'STARTBUF_SPARTAN3E' is not
supported in target 'spartan3e'.

Solution

The STARTBUF module is not supported for the Spartan-3E architecture. However, the STARTBUF_SPARTAN3E symbol was errantly added to the Spartan-3E library. Please remove this symbol from any Sparta-3E designs.

The STARTBUF_SPARTAN3E has been removed from the Spartan-3E library in the latest 7.1i Service Pack available at:
http://support.xilinx.com/xlnx/xil_sw_updates_home.jsp
The first service pack containing the fix is 7.1i Service Pack 1.
