Some help with simulation with uncertainty using $PRIOR TNPRI

Dear all, I would like to perform a simulation (based on a finished model), incorporating parameter uncertainty (for all theta’s, eta’s and epsilons) with the $PRIOR TNPRI option in Nonmem V7.3, using the results of the covariance step as an input. I am still struggling how to implement this. Does anybody have an example control stream I could look at?
