In this first example, we will create simulation of two models: an event generator and a event counter. First, we need to create a new empty package in the user home directory. cd $HOME/examples vle-1.1 -P generator-counter create vle-1.1 -P generator-counter configure build The binary package is now installed into the VLE’s home ($VLE_HOME/pkgs-1.1 or $HOME/.vle/pkgs-1.1). Now, we need to add two DEVS models, the counter and the generator. Copy the file Simple.
