| Issue | Likely Cause | Solution | |-------|--------------|----------| | Component does not appear in Pick Devices | Library files not copied to correct folder; Proteus not refreshed | Double‑check the library path and restart Proteus. Use to load the .LIB file directly. | | “Unknown part” error during simulation | Simulation model missing; model filename or path incorrect | Ensure .MDL or .MODEL files are in the MODELS folder. Verify that the model name in the library references the correct file. | | Simulation runs but output waveform is missing | Missing or incorrect simulation model for SPWM generation; circuit connections incomplete | Check that all EGS002 pins are connected, especially VCC and GND. If using a custom model, verify the SPWM output logic. Try a simplified model. | | Proteus crashes when placing the component | Corrupted library file; conflict with another library | Remove the EGS002 library files and re‑copy them. Scan for duplicate .IDX files in the LIBRARY folder. | | Library path not found | Proteus installed in non‑default directory | Manually verify the path via System → Set Path and ensure your library folder is listed. Add the path if necessary. | egs002+proteus+library+install
Copy the extracted .LIB , .IDX , and any other relevant files into the Proteus LIBRARY folder. If the archive also contains simulation models ( .MDL or similar), copy those into the MODELS folder, typically located at .

Once you've successfully installed the EGS002 library, adopt these practices to keep your Proteus environment efficient and organized:
After restarting Proteus, it's time to verify that the EGS002 component is now available: | | “Unknown part” error during simulation |
| Problem | Likely Cause | Solution | |---|---|---| | "No libraries found" when searching | .IDX file missing or not registered | Verify both files are in LIBRARY and restart Proteus | | "Simulation failed to start" | Missing VSM or SPICE model | Copy any .HEX or .DLL files to MODELS folder | | Component not found after paste | Wrong Proteus version or install folder | Check that the LIBRARY folder path matches your Windows bit version | | Library loading failure | Path configuration error | Go to and manually add the LIBRARY directory | | Proteus crashes on startup | Corrupted library file or version conflict | Re-download the library. If using Proteus 8.15 with 8.16 library, edit the .LIB file's second line with a hex editor to match your version | | "No placement" / blue dots not connecting | Bad junction connection | Ensure connecting wires snap to pin ends and red electrical nodes appear at junctions | | Permission denied errors | Proteus lacks file access | Right-click Proteus → Run as administrator |
