I am having a lot of trouble converting a subcircuit to a new part. I attempted to follow this following tutorial: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000YH5fCAG&l=en-US and was unable to do it correctly. I generated the SPICE NETLIST from the main circuit & the subcircuit, created a new .cir file, then pasted the new SPICE netlist into there, starting with the .SUBCKT part and ending it with .END, and the pins are not mapping properly.
A step-by-step guide would be very helpful, as the Student Edition is currently limited to 50 components per sheet. I need to be able to modulate my digital logic circuits into input/output components.
On the attached file, you can find the "Carry Check" subcircuit, which is what I am trying to modulate into a new part.
A basic overview of what this project is - Creating a full BCD Adder/Subtractor Circuit. This involves then being able to generate the +6 carry from each 4-bit input. That is the purpose of the subcircuit that I am attempting to modulate.
Any and all help would be appreciated.
