Dear Keith,
If you have two signals definitions for a signal with the same name in
different packages, you have defined two different signal (types).
For example, if S is defined in package P1 and S is defined in package P2,
these are two distinct signal definitions with identities:
<<PACKAGE P1>>S
<<PACKAGE P2>>S
It seems that you intend these to be the same signal. In this case, there
must be just one definition in one package and there should be a USE clause
for the other package to make the signal visible (assuming the packages are
not nested). For this reason, you may decide it is best to introduce a third
package containing the signal definitions, which is included by a USE in
each of the other two packages.
