Introduction

Circuit Solver uses a simple drag and drop approach to building circuits. The user must simply drag the elements from the tool box onto the screen. Once the items are placed unto the grid you can wire them and edit their values. After that, all that must be done is to run the simulation.

For AC or Transient Simulation, you can change the Time Step by tapping this icon and setting a new TimeStep that will allow for better viewing of the waveforms. In order to view the waveforms for AC and Transient Analysis try to figure out the period and time constant respectively. One can set the timestep between 1ns and 1Gs to view the waveform slowly or faster.



This button serves as a way to quickly move to the examples/documents. Simply tap this button and you will be sent to the document page.




This button changes some schematic symbols to be drawn as US-based symbols or International Electrotechnical Commission-based symbols. To toggle this button go to the main screen and tap this icon.



This button allows the user to control the amount of magnification that is applied to the circuit. Zooming options included are: 50%, 75%, and 100%.



This button is to close the current file. It is advised to always re-save your circuit if any changes were made. This button does not save changes. If you wish to revert back simply press the undo icon.



To open the menu bar, simply hit this button. Inside the menu bar you will find the components page, the help icon, the undo and redo icon, as well as other icons.



During the design portion of the circuit, One can rotate elements to find a better fit within the layouts boundaries. To do so simply tap the element you wish to rotate and find this icon to the right hand side of the screen. Tap it multiple times to rotate the elements orientation.



Wire options allow the designer to create circuits while managing the flow of wires. This icon will allow the user to travel from point to point without any bends or curves. To use this icon, tap on the element and search for this icon to the right side of the screen. This icon can only be used in certain orientations.



This icon will allow the user to travel from point to point with a bend as indicated in the icon. To use this icon, tap on the element and search for this icon to the right side of the screen. This icon can only be used in certain orientations.



This icon will allow the user to travel from point to point with a bend as indicated in the icon. To use this icon, tap on the element and search for this icon to the right side of the screen. This icon can only be used in certain orientations.



This icon will allow the user to travel from point to point with a bend as indicated in the icon. To use this icon, tap on the element and search for this icon to the right side of the screen. This icon can only be used in certain orientations.



This icon will allow the user to travel from point to point with a bend as indicated in the icon. To use this icon, tap on the element and search for this icon to the right side of the screen. This icon can only be used in certain orientations.



This icon is for viewing graphs on a big screen display. To add a meter, simply tap the meter and search for this icon on the far right hand side of the screen. Once selected the icon will turn light blue, indicating that it's selected.



Once a circuit simulation is complete, the user can save the components used and their connections to other components by tapping this button and saving the file. The file can be accessed through the documents page on the startup menu. From the document menu, the file can be opened by tapping the file icon.



Once a circuit simulation is complete, the user can save the schematic image by tapping this button and giving the image a name and saving it. The image can be accessed through the picture gallery of your android phone. Images can be taken during simulation in order to also capture the output values.



This is the button to initiate the solving algorithm. Once the user hits this icon the solver will perform calculations on the current components on the board and how they're related to one another. During this process, no other components may be added. Likewise, no components may be taken off the grid.



Part of the design process involves eliminating components of little use. To do so just tap the element and look for this icon to the right hand side of the screen. Tap the icon and you're good to go! Element deletion can be undone with the undo button.



Once a component is locked onto the grid system it's properties become editable. In order to edit the properties, tap the element and search for the pencil icon to the right hand side of the screen. Tap the property in the edit menu and provide the new value of the property and hit "enter".



In order to view all the components available, navigate through the menu bar and tap the tools icon. To add components simply tap and drag them on to the board. The menu is designed to help users drop components quickly and once they're done they can simply tap the tools icon once more to revist the board.



To go back to the main start screen, simply tap this button. The start screen gives the user access to the documents saved, information about Circuit Solver, social media sharing, and another link for user instruction. Always save your work before leaving as it's always adviced to save your documents.



Elements such as Operational Amplifiers can behave differently when voltages are applied to specific terminals. This being the case OpAmps are usually drawn either with the positive terminal on the top or bottom. To use this icon, tap on the element and search for this icon to the right side of the screen.



Elements such as transistors can be used to make differential amplifers or current mirrors or sinks. This icon is to help create such circuits. To use this icon, tap on the element and search for this icon to the right side of the screen.



To close the menu bar and access the quick menu buttons, simply hit this button. This allows the user to utilize more of the screen while creating circuits.
