A method is provided of embedding tooling control data within a mechanical fixture design to enable programmable logic control verification simulation. The method includes the steps of constructing at least one of a mechanical fixture design, a workcell design, and a controls design. The method also includes the steps of executing a virtual programmable logic control (VPLC) simulation with a VPLC verification simulator to verify the at least one of the mechanical fixture design, the workcell design, and the controls design.
