Beginner; thanks for "LTSPICE", but we need more information. What part number? It is a good idea to include the spice file of your project.beginner here, i imported a spice file into ltspice but in the datasheet it says its 8 pins but in ltspice its 5 pin
Simulation does not really have any concept of pin numbers. Only the signals that are relevant are implemented. As has been mentioned power pins are often omitted as well as multiple instances of a basic element like an AND gate. A simulation model for an LM393 dual comparator only has a single instance of a comparator and is not tied to a physical package,beginner here, i imported a spice file into ltspice but in the datasheet it says its 8 pins but in ltspice its 5 pin, did i do something wrong or am i missing something

Not knowing what part, it is most likely that the part has 5 pins what are connected. "+", "-", out, +supply, and -supply, then two no-connects.
so in simple terms ground and Vcc will not be there?There

They are for some chips but not for others. When simulating ICs in a standard logic family, for example, it is assumed that inputs are within the logic range (e.g 0V-3.3V) associated with that family.so in simple terms ground and Vcc will not be there?
They will be "there", but by a different method than explicit wire connections.so in simple terms ground and Vcc will not be there?
There is no modeling standard for devices, so the modeled behavior and pins for any model may vary.so in simple terms ground and Vcc will not be there?
Thank you for the datasheet. There are two comparators in the IC. SPICE and most CAD programs will only give you pins 1,2,3,4,8., i imported a spice file into ltspice but in the datasheet it says its 8 pins but in ltspice its 5 pin,
