At a Glance
This article serves as a guide to advanced simulation resources in Altium Designer, helping you find the right reference whether you need to troubleshoot a failed simulation, understand simulation-ready generic components, work directly with a SPICE netlist, or create your own simulation models. It is a useful starting point for users who want to move beyond basic simulation tasks and better understand the tools and references available inside Altium Designer. Keep reading to quickly locate the resource that matches your simulation needs and build more confidence in your workflow.
- Learn where to go when a circuit does not simulate, including guidance for identifying whether the issue is in the circuit or the simulation process.
- See which reference pages cover simulation-ready generic components, SPICE netlists, and adding user SPICE code into schematics.
- Find the resource for creating your own simulation models in Altium Designer.

Refer to the following pages to learn more about advanced simulation topics in Altium Designer:
- When a circuit does not simulate, you should identify if the problem is in the circuit or the simulation process. Refer to the Simulation Troubleshooting page for recommendations on resolving issues when performing different types of simulation.
- Altium Designer provides a default library with various simulation-ready components. Use the Simulation Generic Components page as a reference for the parameters of components from this library.
- While the simulation is driven by the circuit captured in the schematic editor, it is the SPICE netlist that is processed by the simulation engine. You can create your own netlist in Altium Designer and also include areas of user SPICE-code into schematics. Refer to the Working with a SPICE Netlist page to learn more.
- When you would like to create your own simulation models, Altium Designer provides you with the means to do this. Refer to the Creating a Simulation Model to learn more.
