DEVSIM - TCAD Device Simulator
DEVSIM is a tool for TCAD Device Simulation, using finite volume methods. The source code is provided by DEVSIM LLC.
The official website is here:
- Python scripting
- DC, small-signal AC, impedance field method, transient
- User specified partial differential equations (PDE).
- Extended floating point precision
- 1D, 2D, and 3D simulation
- 1D, 2D mesher
- Import 3D meshes.
- 2D cylindrical coordinate simulation
- ASCII file format with PDE embedded.
