I began searching for tutorials and getting started guides and kept finding they were all focused on the Windows version. #Ltspice for mac simulatorLTspice is known for being the most widely used free SPICE simulator in the industry. It was originally created by Linear Technology, hence the LT in its name, and was later acquired by Analog Devices who continues to support it. LTspice is a high performance SPICE simulator, schematic capture, and waveform viewer with enhancements and models for making simulation of analog circuits easier. By the way, the strange KiCad results I was getting turned out to be user error. I decided to download it and give it a try. While doing some research on what packages were available, LTspice kept popping up. While doing a circuit simulation in KiCad for another article ( Performing A Circuit Simulation In KiCad) and getting some strange results, I wanted to verify those results with a different SPICE simulator. The LTspice schematic created for this tutorial is available on GitHub for your reference. It enables you to discover and correct issues before actually building your circuits in hardware. LTspice is an extremely valuable tool for designing and simulating analog based circuits. A basic understanding of electronics is expected. #Ltspice for mac how toIf you are familiar with LTspice on Windows, you will notice that the schematic capture window looks completely different.This tutorial will teach you how to create a circuit schematic, perform a simulation, and view circuit waveforms in LTspice for Mac. A new schematic capture window will open with the title of Untitled. Let’s create a new circuit schematic by clicking the Start a new, blank Schematic button from the Welcome to LTspice window. How to create a new circuit schematic In LTspice? Make sure to press the ESC key when you are done. You can also move symbols with Edit > Move. If you make a mistake, you can delete symbols by selecting Edit > Delete from the contextual menu (cursor changes to scissors) and then clicking on the component (s) you want to delete. How do you delete symbols In LTspice on Mac? Double-click the downloaded dmg file to mount the volume. #Ltspice for mac for mac os xClick the Download for Mac OS X 10.7+ button within the Download LTspice section of the homepage to download the LTspice.dmg file. #Ltspice for mac installTransient analysis analyzes changes in voltage and current over …ĭownload and install the application from the LTspice homepage on Analog Devices’ website if you have not done so already. LTspice-Transient Analysis (.tran) In this article, we will explain in detail the transient analysis (.tran) method in LTspice. How to edit the simulation command In LTspice?Ĭlick “Simulate”-“Edit Simulation Cmd” from the menu bar of the schematic editor screen to display the “Edit Simulation Command” screen. Reduce the time required for switch mode power supply (SMPS) simulation by shortening the voltage ramp of the output by changing the value of the soft-start capacitor. To measure the effects of your changes, review the simulation time in the LTspice error log (Ctrl + L). How do you increase simulation time in LTspice? #Ltspice for mac proIn apple->preferences->trackpad a ‘right click’ is called a ‘secondary click’ and on my MacBook Pro its set to be a two finger click. To edit the component value you have to ‘right click’ the component. Select “Transient” and enter “10 m” for Stop time. How do you do transient analysis in LTspice?Ĭlick “Simulate”-“Edit Simulation Cmd” in the menu bar to open the “Edit Simulation Command” screen. You can right-click on a Mac computer by using the control button, two-finger tapping your trackpad, or connecting an external mouse to your device. Click “Simulate”-“Edit Simulation Cmd” from the menu bar of the schematic editor screen to display the “Edit Simulation Command” screen. Simulation command settings can be made on the “Edit Simulation Command” screen. If you want to rotate the component before placing, press “ctrl+R” or click the rotate button. Select the component that you want to add and click “OK”. How do you rotate a component in LTspice on a Mac? In the context (right click) menu, you can Draft->Spice Directive and enter a line for the simulation manually. How do you do simulation on LTspice on a Mac?
