 ADFG can inter-operate with [Cheddar](http://beru.univ-brest.fr/cheddar/) - an open-source scheduling analyzer - by exporting the computed results in a xml format that can be read by Cheddar.
 Scheduling simulation is used to verify the schedules synthesized by ADFG and provide additional information such as numbers of preemptions and max/min/average buffer utilizations over a simulation interval.
-A simple method to test the tool-chain is to use this [virtual machine](https://phobos.univ-brest.fr/vm/CHEDDAR_ADFG_2.vdi) with ADFG and Cheddar pre-installed.
