Hi, I wish to export my circuit sheet so I can read it into my own software. I can easily write software that will manipulate it into any form I require. The trouble I have is actually exporting it. I select FILE->EXPORT NETLIST->LTSPICE FOR THIS SHEET This causes problems. My circuit has a microphone connected to a transistor amplifier connected to two wires that provide power and take signal. The first problem is lack of a signal source. An error "Current circuit doesn't has Voltage Resource or Current Resource symbol, please place it first at left side EELIB or spice library" (SIC) appears. I overcome this problem by simply searching for a voltage resource and placing it, not connecting it to anything. Then it asks for a ground, and I add a ground, again not connecting it to anything. Then it complains again at a lack of spice models but does provide a textual spice circuit which I can select. It has some extra components, and a line '.tran 10m' which just appeared. I can delete all this. Then I can delete my modifications to the sheet, including the ".tran 10m" So my issue is, and I admit it is fairly trivial, why cannot I just create a spice circuit description without having to modify my sheet? Am I doing it wrong?
