Please remember to reset these values to their defaults after simulation so as not to disturb future simulations. You may even try and select an alternative solver engine from the left of the same tab. In LTSPICE, tolerances may be manually set using the control panel's "SPICE" tab. Wider tolerances may allow the circuit to converge at the cost of reduced accuracy. Use trial and error to find the right places. Sometimes bridging a critical component (e.g. The resistors don't have to be connected to GND. can you remove overvoltage protection circuitry while you are simulating normal operation? This will, by the way, speed up your simulation.Īdd dummy resistors to critical nodes as described in the above scenario. Can you simplify it? Can you do (at least for starters) with a plain vanilla circuit without all the bells and whistles of your design? Are there circuit elements which are not required for the issue you are going to simulate? E.g. Before taking a last resort with the measures below, have a look at your circuit. Note that when you've come to this point you are pretty desperate. This error message can be caused by a variety of problems. In case you are not sure where the source of the problem is, you may also be tempted to add additional capacitances (.OPTIONS cshuntintern) or resistors (.OPTIONS gshunt) from every node to GND. For example, you may want to reprogram the Undo, Redo and Duplicate (Copy) commands to a more traditional key combination. Hot Keys can be reprogrammed by selecting a command and then pressing the key or key combination for the command. There is an LT6370.asy entry in the sym folder, however, if I am trying to open the 6370.asc jig it says 'Couldnt find symbol (s): LT6370'. LTSpice is a versatile, accurate, and free circuit simulator available for Windows and Mac. Tools > Control Panel > Drafting Options and clicking Hot Keys. Figure -2 Bypassing an insulation barrier In the Mac OS version of LTspice for MAC I cannot find draft the LT6370 component (not listed).
