This time, however, we will select the A resistor ( res) component, keep clicking (placing resistors) until all resistors are placed, and then end our placement by pressing the ESC key. Next, let’s place our resistors in a similar fashion to the way we placed the transistor above ( Draft > Component). You can even show grid dots to help you with placement by selecting View > Grid Dots from the contextual menu. For zooming in and out, use two-finger pinching and spreading, or alternately, two-finger scrolling. You should now see the 2N2222 model designation shown next to the transistor symbol.Ĭlick and drag the mouse cursor to move the schematic around in the window. Right-click the transistor symbol and click the Pick new transistor button in the pop-up window that appears.
#Spice circuit program for mac update
Let’s update the transistor model from the generalized model to one describing an actual transistor in common use. The completed schematic will eventually look like the one shown below. The circuit we are going to build is a simple small signal bipolar junction transistor (BJT) common emitter amplifier. This means that you will right-click on or in the area of interest and select your command in the contextual menu that appears.

Instead of primarily using toolbar based commands, LTspice for Mac focuses on the use of contextual menus for its commands.
The Mac version contains only three icons in the toolbar versus a multitude of icons for the Windows version. If you are familiar with LTspice on Windows, you will notice that the schematic capture window looks completely different. 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. These same example circuits are also located in the /Applications/LTspice.app/Contents/examples folder.
It will also add an examples folder within the LTspice folder that contains Educational and test jigs example circuits. Upon initial launch of the LTspice application, it will automatically create the ~/Documents/LTspice folder where your LTspice files will be stored.

Installing LTspiceĭownload and install the application from the LTspice homepage on Analog Devices’ website if you have not done so already.Ĭlick the Download for Mac OS X 10.7+ button within the Download LTspice section of the homepage to download the LTspice.dmg file.
#Spice circuit program for mac how to
I figured out how to get things working and thought I would share my knowledge with others also working on Macs. The Mac version works much differently, so those resources didn’t really apply. I began searching for tutorials and getting started guides and kept finding they were all focused on the Windows version.
#Spice circuit program for mac simulator
LTspice 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. This tutorial will teach you how to create a circuit schematic, perform a simulation, and view circuit waveforms in LTspice for Mac.
