The work package

Some of you have asked what work means in the notation:

work.mux41(beh)

All VHDL models must exist in a package.  Rather than force us to create new packages for every model, our tools provide a default package called work.  If you don't tell VHDL what package to put your designs in, they automatically go into the work package.  Thus, the above notation says to look in the work package for the beh architecture of the mux41 entity.
