The Cadence® BSIM6 element implements the latest bulk MOSFET model from the BSIM Group. "The model provides excellent accuracy compared to measured data in all regions of operation. It features model symmetry valued for analog and RF applications while maintaining the strong support and performance of the BSIM model valued for all applications since 1996." BSIM6 is Verilog-A based and implements version 1.0.

See the BSIM6 model website[1] for complete documentation and Verilog-A definition of component models.


Only primary parameters are shown. Secondary parameters follow the BSIM6 model specification/standard.

Operating Points

Operating point information is identical to that found in the Verilog-A definition of the model.

Implementation Details

This model is only supported for AWR® APLAC® HB simulator measurements. The TYPE parameter controls whether the device is NMOS or PMOS. The extraction and simulation temperatures are controlled using the TNOM and TEMP parameters, respectively. Parameter default and truncation values are identical to those found in the Verilog-A definition of the model.


This element does not have an assigned layout cell. You can assign artwork cells to any element. See “Assigning Artwork Cells to Layout of Schematic Elements” for details.
