BSIM4 Model Verilog-A Implementation<\/h1>\n

BSIM4 Model<\/strong><\/p>\n

The Verilog-A hardware description language opens many areas to SPICE users in the field of compact models, allowing manufacturers and universities to study or customize the existing models.<\/p>\n

Berkeley BSIM4 model is developed to explicitly address many issues in modeling sub-0.13 microns CMOS technologies and RF high-speed CMOS circuit simulation. Due to its forefront use, BSIM4 was a good candidate for Verilog-A porting.<\/p>\n

The Silvaco Verilog-A porting is based on the BSIM4 version 3.0 released on May, 9th 2003. The version 2.6.0.R of\u00a0SmartSpice<\/em><\/strong>\u00a0Verilog-A interface has been used.<\/p>\n

Verilog-A Porting<\/strong><\/p>\n

Silvaco BSIM4 Verilog-A implementation includes all the major physical effects and associated parameters of the original Berkeley version 4.3.0: short\/narrow channel effects on threshold voltage, non-uniform doping effects, mobility reduction due to vertical field. All the equations and related parameters have been implemented in a Verilog-A module. The result is a 4,400 lines Verilog-A module.<\/p>\n
