While I'm not new to electronic circuits, I'm fairly new to EDA.
I have played around with Spice a very long time ago but really had no need for it. Now I do. I've been trying to simulate a simple half wave rectifier for the last week or so and keep getting wrong results. Let me explain. The first screenshot shows the circuit, a very very basic 1/2 wave rectifier, but as you can see from the second screenshot, while the voltage from the net labelled op is correct, the voltage across the resistor is inverted. Basic electronic theory tells you that this can never happen. Notice the pin labels on the resistor. Now after trying and searching for almost two days, I inadvertently reversed the connections on the resistor and the output is now correct as shown in the third screenshot. I thought it was the version of GNUCap I installed from the Debian repos. I built the lastest tarball but still the same result. The circuit does not even simulate with NGSpice. The simulation runs forever while using 100% CPU. Again, I build the lastest NGSpice (25), but still the same result. After trying searching for how a resistor is modeled in SPICE, and not getting anywhere, I'm at my wit's end. Any help is greatly appreciated. Comments are closed.
