Changing the resolution is like seeing the results more clearer, more specific, more detailed. To change the resolution of our simulation result, change the "step" or "number" in AC simulation. Double-click the "ac simulation" and a dialog box will pop-up to change parameters. Because our supply has 100 Hz, we will start simulation from 0 Hz to 100 Hz. We will also change the parameters of AC simulation. Change the frequency of supply voltage from 1 GHz to 100 Hz, 1 V to 10 V. We will try to change the value of it.ĭouble-click the supply voltage and a dialog box will appear to change the parameters. It started from 1,000,000,000 Hz or 1 GHz because the parameters of our circuit starts from 1 GHz. 1e09 means 1 to the exponent of 9 or equal to 1,000,000,000. We will consider first the tabular diagram and see the result.Īs we see in the result in tabular form, the "acfrequency" values are 1e09, 1.5e09, 2e09 and so on. The display the result, we will use Tabular and Cartesian. Save the file and then click simulate from simulation menu. Make a wire label and select AC simulation to perform AC simulation process. We will consider this circuit as an example.ĭo the same process before starting the simulation as stated above. If two source are available (AC and DC), use the AC Simulation Scheme. If it has AC voltage or current source, then it is AC. To identify the circuit if it was in AC form, look again for the supply voltage or supply current. For in of 10 V, the output voltage is 6.25 V. Then it was the result of the simulation. As you see, the graph portion of table will be filled with input and output. For this, I will display the input and the output of the circuit by double-clicking the input and output label. Dialog box will pop-up to change the parameters of the table. Place the table diagram by clicking and dragging to the work area. So, we will try displaying the result in tabular form. The rest is not appropriate for DC simulation. DC simulation, the appropriate diagram to use in table. These diagrams will be used to display our the result simulation process. Simulation diagrams will also be available. This tab will be used as a window to place our simulation result. In this case, there was no problem and simulation 100%.Īfter the simulation, new tab will be created. If there was wrong with simulation, it will be stated in the dialog box the problem. I will not simulate when the project was not saved.Ī dialog box will appear showing the simulation process. I assumed that the project was already saved. Place the "DC Simulation" and click "simulate" on the simulation menu. It is located at the right side of the panel. To use it, click the wire label command and click the point on the circuit to be simulated. It means that it is the part of the circuit that must be visualize through simulation. The "wire label" command will serve as the simulation point. This circuit will be use for the simulation.įor every simulation scheme wire labeling is needed before starting simulation. Otherwise, you can not use DC simulation. If it uses DC voltage or DC current as a source, then DC simulation should be use. To know if the circuits are in DC form, look for the power sources available. This simulation scheme is intended to simulate DC circuits. If the users will master on it, they can also do the same thing for other simulation scheme. Why I only focus on these? Because these are the common and fundamental simulation scheme. QUCS available simulation schemeįor this tutorial, I will explain how to use these common simulation scheme. This tutorial will be a guide for users who have difficulty in using its simulation. I read the QUCS help system in its help section, but I did not fully understand, it was not fully stated in details. To my experience, I took time before I fully understand QUCS process of simulation. There are many pre-defined settings before starting. Others also just click "simulate" to start. Some software used "Play" button to start simulation. As for me, simulation in QUCS is very different from other software. This tutorial aims for the users of QUCS circuit simulator on how does its simulation works. I encourage to try other simulator software see the differences)
