You can import simulation results from LTspice® into SIMetrix. This involves the following steps

1. Set LTspice® to output data in ASCII form. To do this open the LTspice® control panel and make the setting as shown on the right. This setting needs repeating each time LTspice® is restarted
2. Run LTspice® simulation
3. Make a note of any nodes you wish to plot in SIMetrix. If they are not explicitly labelled you will need to find the name allocated by LTspice®. Place the mouse cursor over the node to see the name displayed in the status bar.
