Currently, design techniques that can predict the irregular behavior that comes with larger and faster electrical circuits in the design stage are essential for lowering product cost, increasing reliability, and shortening the development period. Hitachi has independently developed the ECTAS electromagnetic field simulation technology and is using it in design and problem solving for various products.

There is concern that increases in electrical circuit capacity and speed will be accompanied by longer product development times and higher costs. The most important factor is that even minor changes in component placement and wiring pattern cause large changes in circuit behavior. That fact is what links predictive design to cheaper and more reliable products and a shorter development period. The ECTAS electromagnetic field simulation technology developed by Hitachi faithfully models various kinds of wiring as actual 3D shapes to evaluate the electrical characteristics (wiring inductance). It provides highly accurate analysis models for wiring implementations that can be used in various types of circuit analysis programs, allowing electrical characteristic design that takes transient phenomena into account.Also, although the analysis models provided are compact and use the minimum required elements, they are highly accurate.
