| Oct 30, 2019 at 13:18 | comment | added | Olaf Sikorski | @a concerned citizen Are the models used in CAD software such as Cadence or Synopsys not SPICE models? Do their simulators (Spectre and HSPICE) not use SPICE models? I know that you can't predict everything in a simulation, but there is a difference between the nmos provided by LTSpice and the nmos provided as part of a PDK. As mentioned in the question, I need the models to include subthreshold region operation, which I know is not accounted for in basic models. | |

For example, LT gladly provides users with it's IC chip models (opamps, voltage regulators, etc.), but these are empirical models derived from component performance, AFAIK. These programs don't simulate single transistors that comprise their products, but merely specify the relationships between voltages and current on various pins. The MOS models they provide are either very basic or empirical models of specific power MOSFETs. | |
