...At its core is the Level Set framework, allowing for an implicit surface description of material surfaces and interfaces. Within this framework models for geometry manipulation such as boolean operations and chemical mechanical planarization have been implemented. The tool supports several etching and deposition models, essential for the understanding of process-induced phenomena in micro- and nanoelectronics. The model support includes but is not limited to silicon etching in SF6/O2 and HBr/O2 plasmas, silicon dioxide etching in CF4 plasma, anisotropic wet etching of silicon, CFx polymer deposition on silicon, as well as several adaptable deposition models. ...
Simulator for Siemens S7-200 PLC. It supports boolean operations, counters, timers, rise up and fall down contacts, and mathematics operations, with integer and real numbers, like sin, cos, tan. Comments and advise are well accepted!
The Boolean Network Toolkit is an efficient and easy-to-use object-oriented C++ library which enables researchers to simulate ad carry out experiments (like attractor sampling and Derrida plot computation) on large boolean networks.
