3.3i Foundation ISE Project Importer - Default net names are renamed by the exporter.

Description

Keywords: ISE, Project Navigator, Importer

Urgency: Standard

General Description:
For schematics where the net from the IPAD or to the OPAD is not explicitly
named, the Foundation VHDL netlister will add characters to the beginning
and end of the default name. Any UCF constraints concerning these pads
will then be invalidated if that VHDL netlist is used to implement a design.

For Example:
$Net00016_ is renamed to X36_NET00016_X95 in the VHDL netlist.

Solution

As a general rule, all nets or busses of this sort should be named before
attempting to import the project into ISE.
