She didn't need a perfect footprint for simulation, but she added a 16-pin DIP header footprint so that later, if she designed a PCB, the layout would match a real module's pinout.

Prof. Aris gave her an ultimatum: "If you can't show me a working simulation by tomorrow morning, you present on paper only. And that's a failing grade for the preliminary review." --- 4 Channel Relay Module Library For Proteus

She saved it as 4CH_RELAY_MODULE.LIB and placed it in the Proteus LIBRARY folder. Then, in Proteus, she used Tools > New Component to combine the schematic, footprint, and properties (e.g., "Operating Voltage: 5V", "Logic: Active LOW"). She didn't need a perfect footprint for simulation,

Here’s what she did (and what you can learn from her steps): if she designed a PCB
