How can I select a different simulation model?
Many of the components within Circuit Wizard and Livewire support a range of models. With models you can simulate the different characteristics of named real-life components. An NPN transistor, for example, can be made to act like a BC108, BFY51 or a ZTX300.
 
Ideal simulation models
Some components also feature an ideal model. The ideal model is better for teaching basic concepts as it provides a behaviour that is simplified or typical for that component.
For digital components, the ideal model provides a drive capability better than TTL with low power requirements that are equivalent to CMOS. Any voltage below 0.3 VDD is treated as a low signal and any voltage above 0.7 VDD is treated as a high signal (between these the logic level is undefined).
 
Selecting simulation models
To select a simulation model, first drag onto your design the component symbol, for example an NPN transistor.
To select a model in Circuit Wizard, then double-click with the left mouse button on the component within your design and then choose from the Models list in the window that appears.
To select a model in Livewire, then click with the right mouse button on the component within your design and then choose from the Models option that appears.
If the simulation model you want to select is not listed, please click here for more information.
