exporting variables

[AB]

Hi all,

I have a variable in one component:

constant number : bus7 := "0001000";

But, is there any way of using this variale in another a component of my
circuit?

I know how to connect components together, but the component with the
variable, has no inputs or outputs just variables.

Thanks,
Kay

That is a constant, not a variable.
Constants can be shared by declaring
them in a package and adding a USE statement
to each unit that needs it.

variable, has no inputs or outputs just variables.

A structural design can
only share register values using signals.

The only way to share variables across
a design entity is to use a single process
style.
