Problem Title:
XABEL6, Foundation F1.3/F1.4, NGDBUILD:	Warning- logical net VCC_net
(or GND_net) has no load



Problem Description:
Keywords:  VCC, GND, VCC_net, GND_net, loadless, abel

Urgency:  Standard

General Description:

When compiling an XABEL design with the M1 Implementation tools, NGDBuild may is
sue a warning:
WARNING:basnu - logical net "VCC_net" has no load
WARNING:basnu - logical net "GND_net" has no load


Solution 1:

This warning may be safely ignored.  The XABEL compiler
automatically inserts the nets VCC_net and GND_net into the
synthesized EDIF netlist.  If there are no equations in the
ABEL source code which would result in logic tied directly to
VCC or GND, then these warnings indicating that these
dedicated nets are loadless will result.
