Nexxim Design Examples
Nexxim is a simulator for high-speed, high-density circuit designs. Nexxim provides analyses in the time and frequency domains for all levels of projects; on the characterizing of individual transistor models to the analysis of large-scale integrated devices and communication channels. The following topics provide examples of circuit analysis using Nexxim.
This topic assumes that you are already familiar with Electronics Desktop and Nexxim basics discussed in the online Getting Started Guides. Work through the sequence of design topics described in this topic to learn to:
- Load schematic example designs into Electronics Desktop (Electronics Desktop) for analysis using Nexxim.
- Set up and run the applicable analyses.
- Display simulation results using the Electronics Desktop reporting functions.
The examples are grouped by focus:
- Nexxim RF
- Nexxim SI
