Web27 mei 2014 · My somewhat lame explanation is this: One of the things that LTspice needs to do, is to invert the matrix of equations that describes the circuit. If that matrix is very close to singular (very "stiff" and not easy to manipulate), it means it is unable to successfully invert the matrix. In a very very crude sense that is like calculating the ...
