Q.  What are technical support tools?

A.  These tools are to help you design virtual circuits. They include multi-purpose simulator models using S-parameters and Netlists, models for other commercial simulators, and "SEAT," which is a component characteristic analyzing software.

Q.  Why should I use these technical support tools?

A.  Recently, electrical circuits designs use simulation technology. In order to improve simulation accuracy, it is very important to acquire a simulation model that is as close as possible to the actual usage. For example, when a 1uF capacitor is used, ESR (Equivalent Series Resistance) and ESL (Equivalent Series Inductance) differ depending on the size. Therefore, if you create a circuit using the ideal capacitor determined by simulation, actual results may be very different. By using a simulation model, you can attain results that are as close as possible to actual phenomena.

Q.  What kinds of technical support tools are available?

A.   We provide a multi-purpose model for other commercial simulators using S-parameters, equivalent circuit models, and Netlists.
We also have an exclusive model for simulators from other companies such as ADS from Agilent Technologies, Ansoft Designer&NEXXIM from Ansoft, Microwave Office from AWR, and Allegro PI from Cadence. This exclusive model is easier to use than the multi-purpose model.
In addition, “SEAT,” a component characteristics analyzing software that is equipped with functions for displaying and simulating various component, is also available.

Q.  What is the difference between the multi-purpose model and the exclusive model for commercially available simulators?

A.   Basically, the two models are the same. However, the exclusive model for commercially available simulators has more features. For example, the exclusive model can layout components easily using a pallet and can confirm land patterns.

Q.  What is the difference between S-parameters and Netlists?

A.  S-parameters can be used to explain the amount reflection and transmission when a signal is given to a component that is used as a black box.
A Netlist contains equivalent circuit information that can be read using a simulator after a component is made as an equivalent circuit.
Usually, Netlists are used for analyzing time domains such as transient analysis. S-parameters are used for analyzing frequencies.
S-parameters use actually measured values, while Netlists themselves are equivalent circuit models and actually measured values are often different from the Netlist, especially in the high-frequency range.

Q.  What about new products and discontinued models?

A.  We update product data every six months. New and discontinued product information will be included in these updates.
