Due to the increased use of memristors, and its many applications, the use of emulators has grown in parallel to avoid some of the difficulties presented by real devices such as variability and reliability. In this paper, we present a memristive emulator designed using a Switched Capacitor (SC), this is, an analog component/ block and a control part or block implemented using stochastic computing (SCo) and therefore fully digital. Our design is thus a mixed signal circuit. Memristor equations are implemented using stochastic computing to generate the control signals necessary to work with the controllable resistor implemented as switched capacitor.

Verification of analog/mixed-signal (AMS) circuits is complicated by the difficulty of obtaining circuit models at suitable levels of abstraction. We propose a method to automatically generate abstract models suitable for formal verification and system-level simulation from transistor-level simulation traces. This paper discusses the application of the proposed methodology to a switched capacitor integrator and PLL phase detector.
