Subject: Handling Unconnected Ports & Naming DesignWare Instantiations
John, Question for the masses: What's the accepted way of leaving a port
unconnected? We're instantiating transceivers in our design (to communicate
with off-chip signals), but the transceiver model has ports that we don't
need to use. Do we tie all these ports to an "unused" signal? Wouldn't this
tie them together then? How do I handle this?
Also, how would I go about naming the instantiation of a DesignWare adder
when implemented as an arithmatic operator, such as "c <= a + b;". Our
compilation guys need to know this stuff for their compile scripts. We would
like to ensure the names of such operators are known, regardless of the size
or number of adders in the design.
