Questions tagged [simulation]

About tools to simulate circuits. Specify the tool used.

Simulations use mathmatical models to predict the behaviour of a circuit. The Wikipedia article is a good starting point to learn more. This tag should be used for questions related to circuit simulation tools (software).

Questions specifically about the popular SPICE simulator, or one of its many descendant , should also be tagged .

Typically circuits are described to the simulator in either a text file (like a SPICE netlist) or as a graphical .

Simple Circuit Simulation tutorial

For the last few days I have been trying without any luck to find a good tutorial on simple circuit simulations. I am a relatively new hobbyist and I figure if I use simulations and play around the circuit and see the output I would learn more. Can…

Testing/Simulating Circuits

What techniques do you use for testing/simulating circuits? As at my college we use Circuit Wizard which we have to simulate our circuit on. I am looking for something a bit more advance. I have tinkered with SPICE but for more sophisticated…

Circuit Simulator

I just recently started to study circuits. I have a homework assignment and I need to simulate some circuits, but I don't know what simulator should I use. I was using CircuitLab but as I don't know how to configure it I don't know what to expect in…

HFSS - 50 ohm Coaxial line terminated with 50 ohm impedance boundary. |S11| too large

I'm modelling a 50 ohm coaxial cable in HFSS that is excited with a waveport and terminated with a 50 ohm impedance boundary. The Z0 of the wave port is 50 ohms (refined through tweaking dimensions of the Teflon and pin size around standard SMA 50…

Share circuits between different simulators

How do we share circuits between different simulators ? Say, we have 3 simulation tools ; Proteus, multisim, and LTSpice ( or anything else). How do we share the circuits made in one of the simulation tools ? Say I have a circuit in Proteus. Now I…

Why do I get a voltage spike when charging a capacitor through a diode?

I'm simulating simple circuit, where a small capacitor is charged through a 10R resistor and a diode. The capacitor can be discharged through a switch. When the circuit is powered on, the switch is closed, the capacitor is not charging and current…

Microstrip Patch antenna has improved impedance matching but no improvement on gain

I am trying to design and understand a 30mmx45mm patch antenna. The setup is below, but it is a 50mm long, 50ohm T.L. feeding the patch antenna on Rogers5870 circuit board. I am trying to do impedance matching with an open circuit stub. My issue is…

Simulating Smoothing Caps in TINA

I'm trying to simulate the workings of smoothing capacitors in TINA-TI. I have a varying voltage source (sine wave varying from 4.5-5.5V) and 2 capacitors (1uF and 100uF) connected. The load is a 1000 ohm resistor, and VF1 is the test point. After…

Is there a way to draw arbitrary components in TinkerCAD schematics?

I have my students use TinkerCAD to make simple circuits. The ability to simulate Arduino code is a great feature. Now, I'd like my students to be able to make schematics that show how their Arduinos will plug into, e.g. a BT<-->Serial board. I…

SIMetrix simulator with Capacitor Voltage Divider

How to fix the Capacitor Voltage Divider (CVD) schematic to see C2 Out voltage? When I run simulation in OASIS SIMetrix I get: *** ERROR *** Singular matrix This may be due to a floating node or a loop of voltage sources and/or inductors. In…

ADS Simulation: Why doesn't the diode rectify the signal?

As titled, the diode in my half-wave rectifier did not rectify the AC signal. Vd1 is still AC signal. Therefore Vout ~ 0V. Why could that happen? The diode's parameters are SPICE parameters. The strange thing is, with exactly that diode's model,…

Electronic circuit simulator for tracing current paths?

I've started learning electronics a few weeks ago and almost everything was pretty straightforward to me. I was able to understand with relative ease the fundamentals of a basic circuits and there working process. However, recently all the…
