Proteus allows you to create new components using existing primitive models or subcircuits. Since no native SPICE model exists, you build a .
The SG3524 is already present in most Proteus versions (7, 8, and ARES/ISIS) under: sg3524 proteus library download upd
. While it is a staple in power electronics, it is not always included in the default Proteus library, requiring users to manually add its model for simulation. ariat-tech.com Understanding the SG3524 IC Proteus allows you to create new components using
Proteus is looking for a textual model, but your library has a HEX model. Fix: Edit the component properties. Right-click the SG3524 on your schematic -> Edit Properties -> Set "Other Properties" to PRIMITIVE=ANALOGUE,SUBCKT=1 . This forces Proteus to treat the HEX file as a subcircuit. While it is a staple in power electronics,

(Regulating Pulse Width Modulator) is not natively included in the standard Proteus component library. To use it in your designs, you must either download a third-party library or import a SPICE model for simulation. Finding and Downloading the Library
