We present "spotlight abstraction" as a generic abstraction technique for the analysis of systems comprising an unbounded number of communicating agents. The abstraction principle is heterogeneous in the sense that the behaviour of a finite number of agents is preserved while the others are only abstractly represented. The precision of the abstraction can be tuned by an iterative procedure based on the analysis of counterexamples. Going beyond existing work, we show how to use the spotlight
