Charge Pump Phase-Locked Loops and Full Wave Rectifiers for Reachability Analysis
Keyword(s):
Analog-mixed signal (AMS) circuits are widely used in various mission-critical applications necessitating their formal verification prior to implementation. We consider modeling two AMS circuits as hybrid automata, particularly a charge pump phase-locked loop (CP-PLL) and a full-wave rectifier (FWR). We present executable models for the benchmarks in SpaceEx format, perform reachability analysis, and demonstrate their automatic conversion to MathWorks Simulink/Stateflow (SLSF) format using the HyST tool. Moreover, as a next step towards implementation, we present the VHDL-AMS description of a circuit based on the verified model.
