Open Source TCAD Software


  • Aestimo 1D Schrödinger-Poisson Solver


  • Archimedes is the GNU package for the design and simulation of submicron semiconductor devices. It is a 2D Fast Monte Carlo simulator which can take into account all the relevant quantum effects, thank to the implementation of the Bohm effective potential method. (excerpt)

  • See nano-archimedes below

Charon Device Simulator

  • Charon is an open-source semiconductor device modeling code, widely referred to as a TCAD (technology computer-aided design) code, developed at Sandia National Laboratories.

  • Charon offers the solution options of stabilized Galerkin (supg) methods, Scharfetter-Gummel (CVFEM) methods and a unique Exponentially-Fitted Flux Petrov-Galerkin method (EFFPG).

  • By applying finite element & massively parallel solver technology, the tool is capable of modeling at unprecedented fidelity including transient gamma and neutron irradiation effects. (excerpt)

Erwin Jr

  • Open source design and simulation program for quantum semiconductor devices including quantum cascade lasers






  • nano-archimedes is based on the platform implemented for Archimedes (see above).

  • The code is able to simulate time dependent, full quantum, multi-dimensional phenomena such as wave phase breaking and single electron ballistic transport with open boundary conditions, electron dynamics in molecular systems, etc.

NanoFEM platform

  • ‘’A Software Platform for Nanoscale Device Simulation and Visualization – NanoFEM Platform ‘’


  • NanoTCAD ViDES is a device simulator able to compute transport in nanoscale devices, and it is particularly devoted to the assessment of the performance of graphene based transistors. In particular, it self-consistently solves the Poisson equation (both 2D and 3D) together with quantum transport equation within the NEGF formalism.
