Ok, let me explain how I ended up opening this thread. I have this instrument cluster from my car and its schematic wasn't available from the manufacturer. So I reversed engineered the schematic from the PCB. On the board there is a circuit that alerts the driver in case he forgot to turn off the headlights before stepping down from the vehicle. That alarm circuit is using one HEF4001B, some passives and a transistor that drives a buzzer. The alarm sounds when two conditions are met: headlights on, which feeds +12V to VDD of 4001, and driver's door open, which feeds GND to VSS of 4001. So I wanted to simulate that circuit in Proteus. That proved to be an impossibility.
Conclusion: it is not about doing a new design, it is factory made. It is a specific question about simulating that circuit, exactly as it is, in Proteus.
