Technology CAD include Synopsys, Silvaco, Crosslight, Cogenda Software|VisualTCAD, Global TCAD Solutions and Tiberlab. The open source GSS, Archimedes, Aeneas, NanoTCAD ViDES, DEVSIM, and GENIUS have some of the capabilities of the commercial products. TCAD Central maintains an information resource for available Open Source and Commercial TCAD software. Technology CAD Technology CAD (or Technology Computer Aided Design, or TCAD) is a branch of electronic design automation that models semiconductor fabrication and semiconductor device operation. The modeling of the fabrication is termed Process TCAD, while the modeling of the device operation is termed Device TCAD. Included are the modelling of process steps (such as
Computer-assisted proof the runtime environment and hardware. Other mathematicians believe that lengthy computer-assisted proofs should be regarded as "calculations", rather than "proofs": the proof algorithm itself should be proved valid, so that its use can then be regarded as a mere "verification". Arguments that computer-assisted proofs are subject to errors in their source programs, compilers, and hardware can be resolved by providing a formal proof of correctness for the computer program (an approach which was successfully applied to the four-color theorem in 2005) as well as replicating the result using different programming languages, different compilers, and different computer hardware. Another possible way
