[Si2 CMC] to Standardize SPICE Model for SiC MOSFET

May 03, 2021 // By Peter Clarke [eenewsanalog.com

The Compact Model Coalition (CMC) working group of the Silicon Integration Initiative (SI2) has agreed to standardize a model for the behaviour of a silicon-carbide MOSFET.

Silicon-carbide offers higher efficiency and faster operation than silicon and has been adopted for several power applications including photovoltaic inverters and converters, industrial motor drives, electric vehicle powertrain and EV charging, and power supply and distribution. A CMC working group will oversee the model development with Analog Devices, Cadence Design Systems, Infineon, Qualcomm, Siemens EDA, Silvaco and Synopsys set to participate.

"I'd encourage companies with a stake in silicon-carbide devices to join this effort and help guide selection of the model which best represents their intended use," 
advised Peter Lee, chair of the CMC.

Now in its 25th year, the Si2 Compact Model Coalition provides semiconductor manufacturers, designers, and simulation tool providers a means to pool resources to fund standardization and optimization of standard compact SPICE models and standard interfaces to promote simulation tool interoperability [Read more...]

Abstract: Nanosheet FETs (NSFETs) are expected as future devices that replace FinFETs beyond the 5nm node. Despite the importance of the devices, few studies report the impact of NSFETs in the full-chip level. Therefore, this paper presents NS3K, the first 3nm NSFET library, and presents the results in a full-chip scale. Based on our results, 3nm NSFET reduces power by -27.4%, total wirelength by -25.8%, number of cells by -8.5%, and area by -47.6% over 5nm FinFET, respectively, due to better devices and interconnect scaling. However, careful device/layout designs followed by routing-resource considering standard cells are required to maximize the advantages of 3nm technology.

Abstract: The topic of this paper is the development of compact models reaction-advection-diffusion phenomenon compatible with a SPICE simulation environment. From a mathematical perspective, biological systems that involve such phenomena are described by partial differential equations, which are not naturally handeled by SPICE. Our approach consists of discretizing these equations according to the finite-difference method and converting the resulting set of ordinary differential equations into an assembly of elementary equivalent electronic circuits written in Verilog-A. The main interest of this approach is the capability of coupling such models with third-party SPICE models of electronic circuits, sensors and transducers as well as biochemical models that can also be written in SPICE. The tool is validated both on simple problems for which analytical solutions are known and by comparison with a finite element simulator of reference
