crs 317 and EVE Simulator

I am learning how to use the EVE network simulator. My lab will consist of the mikrotik routers, so using the CHR for the image and it works well. i am trying to figure out how to simulate the swOS in EVE. I know that this switch can run router OS, so I guess I could use another router node to simulate that. I was hoping to use swOS and simulate that. Any ideas on how to do this.
