I am completely new to using any type of SPICE program for evaluating electrical circuits. However, having joined the ECAD movement, I have at my disposal a teaching guide on using LTspice IV and the software version LTspice XVII.
Therefore, I was bound to come up with compatibility issues; although I am not sure that this is one of them.
Basically, I have created a diode library to use with my circuits. However, when I attempt to run a simulation with the schematic that requires this library, I get the following error message "Missing expression in ..." (see attached picture).
Please note that the simulation works fine when the ideal diode within LTspice is used instead.
