Depends on the library. Some libraries provide only the schematic symbol (simulation disabled) – these are for PCB design only. Others include a full SPICE model. Read the library description.
Check the inductor's saturation current. In Proteus, if the inductor model has no current limit, it might simulate as a short. Add a series current limit property to the inductor, or use a virtual inductor from the ACTIVE library.
If you need help finding or configuring your circuit files, let me know: What of Proteus you are running?
No. Proteus 8.x includes many power ICs (e.g., LM317, LM7805), but not the LM2596 series. You must add it manually. lm2596 library for proteus
Without this library, you are flying blind. With it, you can test input voltage sweeps (e.g., 12V to 40V), load transients, and output capacitor ESR effects before soldering a single component.
While Proteus includes standard linear regulators like the LM7805 in its default installation, it lacks a native, pre-configured SPICE or VSM simulation model for the LM2596. Adding a custom library bridges this gap, providing both the schematic symbol for ISIS and the PCB footprint for ARES. 2. How to Download the LM2596 Proteus Library
To make the LM2596 appear in your Proteus component list, you must place the extracted .LIB and .IDX files into the correct directory. The file path varies depending on your version of Proteus. For Proteus 8.x (Standard Installation Path) Close Proteus if it is currently running. Copy the extracted LM2596 .LIB and .IDX files. Depends on the library

Complete Guide to Installing and Using the LM2596 Library for Proteus
Connect the positive terminal of your DC Voltage Source (set to 12V or 24V) to the VIN (Pin 1) of the LM2596. Place the 100µF input capacitor parallel to the power source, close to Pin 1. Read the library description
If Proteus throws a simulation crash error stating the LM2596 model is missing, your downloaded library only contains schematic data, not simulation data. Ensure your downloaded library explicitly features SPICE simulation capabilities. If it lacks simulation parameters, you must use it solely for footprint routing in ARES PCB layouts.
Since the LM2596 is not built-in, you need to download a third-party library. Several sites provide custom models for Proteus:
