It also refers to the BSIM group located in the Department of Electrical Engineering and Computer Sciences (EECS) at the University of California, Berkeley, that develops these models. Information on Downloading Technical Documentsĭownloadable materials, including lecture materials from ROHM-sponsored seminars and a selection guide for DC-DC converters, are now available.Family of MOSFET transistor models for integrated circuit designīSIM (Berkeley Short-channel IGFET Model) refers to a family of MOSFET transistor models for integrated circuit design. In the next article, we will explain what is possible using SPICE. SPICE models offered by ROHM can then be downloaded. Next, click on “ROHM” from the selection of manufacturers.
A downloaded evaluation circuit can be modified and customized.Īccess the PSpice Community of Cadence, and click on “Model Library”. The PDF file also shows simulation results. A PDF file will open upon clicking on “SIMetrix SPICE Simulation Data File” in the file, the download will begin. Upon finding a reference circuit that matches your design, click on “Reference Document Download”. ROHM currently provides the following SPICE models.Įvaluation circuits can also be downloaded from “Reference Designs”. Evaluation circuits are currently intended for use with SIMetrix. The following page appears upon searching on products and product categories and then clicking on the relevant part number, the SPICE model and an evaluation circuit can be downloaded. Nearly all evaluation circuits and demo circuits are for use with specific simulators, and so it is important to check the simulator for which the circuit is intended.īelow, details for downloading SPICE models and evaluation circuits from the ROHM website and from the PSpice Community are provided.įrom the main page, click on Technical Support, and then click on Design Support/ Design Simulation Models. Also, circuit examples in which external components required by specific ICs and devices are positioned and optimized are provided by manufacturers, in the guise of evaluation circuits and demo circuits these can be used to greatly speed up design. Moreover, SPICE models of different manufacturers can be downloaded from the PSpice Community managed by Cadence.
SPICE models of specific transistors, ICs and so on are provided on the websites of the manufacturers. SPICE models of general-use transistors, resistors, capacitors and other basic components may be included with the simulator.
In order to execute a simulation, the simulator software, and SPICE models (macro models) that provide parameters for the devices and elements, are necessary.
