This work describes the development of a model for the memristor, a novel nanoelectronic technology. Only items listed in the dataset list can be put into the graph.A Simple Memristor Model for Circuit Simulationsįullerton, Farrah-Amoy Joe, Aaleyah Gergel-Hackett, Nadine Department of Chemistry Physics Team Besides the node voltage ‘divided.V’ the current through the DC voltage source V1.I is available. By double clicking ‘divided.V’, the graph (values in a tabular plot) is added to the diagram. Choose the tabular (list of values) diagram and place it on the data display page. Also, the Components tab changes its category to ‘diagrams.’ After the simulation has been done, the related data display is shown. This is started by choosing the Simulation → Simulate menu entry, clicking the simulation button (the gearwheel) or by pressing the F2 shortcut. The final DC voltage divider is shown in Fig. This can by done by choosing the File → Save menu entry, clicking the Single Disk icon or by pressing the Ctrl + S shortcut. Now the complete schematic for the voltage divider is ready and can be saved. The dialogue is closed by pressing the Enter key or pressing the Ok button. Wire labelling can also be done using the icon in the toolbar, by pressing the Ctrl + L shortcut or by choosing the Insert → Wire Label menu entry. This is done by double clicking the wire and giving it an appropriate name. If you want voltage between the two resistors (the divided voltage) be output in the dataset after simulation, you need to label the wire. You can do this by choosing the ‘DC simulation’ block, which is found in the Components tab in the simulations category. Placing simulation blocks.The type of simulation that is to be performed must also be placed on the schematic. 7, the ground symbol is placed at the negative terminal of the DC voltage source. The user can also choose the ground symbol icon or simply press the Ctrl + G shortcut. The ground symbol can be found in the Components tab in the lumped components category. You can leave the wiring mode by pressing Esc key.įor any analogue simulation (including the DC simulation), there is a reference potential required (for the nodal analysis). In order to change the orientation of the wire, right click it. Left clicking on the components’ ports (small red circles) starts a wire and clicking on a second port finishes the wire. Enable the wiring mode either by clicking the wire icon or by pressing the Ctrl + E shortcut.
Wiring components.Connect the components appropriately using the wiring tool. 6 is for dividing the voltage of a DC voltage source according to the resistor ratio. It computes the node voltage as well as branch currents of the complete circuit. You can even drag-and-drop the components.ĭC analysis is a steady-state analysis. You can right click to rotate the component into its final position. Then move the cursor onto the schematic and click again to put it on its final position.
There are lumped components (such as resistors and capacitors), sources (such as DC and AC sources), transmission lines (like microstrip, coaxial cable, twisted pair), nonlinear components (like ideal op-amp, transistors), digital components (like flip-flops), file components (like Touchstone files, Spice files), simulations (AC or DC analysis), diagrams (like Cartesian or polar plot) and paintings (such as texts, arrows, circles).Įach of the components can be placed on the schematic by clicking it once. 5 is displayed on clicking the Components tab. The available components can be found in the Components tab. On the right hand side, an untitled and empty schematic window is displayed. It contains your schematics, the VHDL files, data display pages, datasets as well as any other data (like datasheets). 4, you will find all the data related to the project.
