Technology CAD 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 diffusion and ion implantation), and modelling of the behavior of the electrical devices based on fundamental physics, such as the doping profiles of the devices. TCAD may also include the creation of "compact models" (such as the well known SPICE transistor models), which try to
Caddie (CAD system) A Microsoft Windows version of Caddie was not released until 1993. In 1998, Caddie was acquired by the South African software development company Billcad Holdings. By this time, Caddie had about 11 000 users. In 1999, Billcad became Planit Technology. In early 2001, Planit Technologies went into liquidation. By March 2002, the British company Advanced Computer Solutions (ACS) bought all the rights from the South African holders and also acquired the Caddie operation within South Africa. ACS was previously Caddie's British distributor. ACS has offices in South Africa and the United Kingdom. Caddie (CAD system) Caddie is a mid-range computer-assisted
