While waveform relaxation methods converge for coupled ODE systems, they may suffer from instabilities for coupled differential-algebraic equations (DAEs). Whereas several convergence criteria are known for index-1 DAEs, we present here a convergence criterion for quasilinear index-2 DAEs for the first time. It applies to systems of coupled ODE/circuit systems. Such systems appear in co-simulation approaches for coupled EM/circuit simulation. Under certain coupling assumptions, we can give a topological interpretation to the convergence criterion.
