EMIStream

EMIStream is an EMI Design Rule Check and Plane Resonance Analysis tool that can suppress undesirable EMI generated from PCB. By eliminating possible EMI issues at the initial design stage, EMIStream will improve efficiency, significantly decrease time spent on the evaluation process, and enable rapid time-to-market.Many choose to use EMIStream for its user-friendly interface, easy 4-step setup, speedy analysis, and seamless work flow with multiple CAD layout interfaces.
Effective April 2026, Microwave Factory Co., Ltd. has succeeded the development, maintenance, and sales of DEMITASNX following a business transfer from NEC Solution Innovators, Ltd.

EMIStream Key Functions and Options

EMI Rule Check

EMIStream was developed by engineers who were facing EMI problems with their own products and research. EMIStream is a result of research and development by these engineers seeking a solution for their real-world EMI problems.
Over 150 rules were investigated, and were boiled down to 15 critical rules.

Power/ Ground Resonance Analysis

EMI is easily increased if resonance occurs between the power and ground planes. The power and ground plane resonance analysis function takes into account plane shapes, capacitors, and distance between the power/ground planes to analyze resonance based on the PEEC (Partial Element Equivalent Circuit) method.

ESD Rule Check Option

A discharge can occur when an electrically charged object, including a human body, touches an electronic device. This phenomenon, called ESD (electrostatic discharge), can cause malfunction and failure of electronic devices. EMIStream ESD Rule Check Option will detect areas where ESD tolerance levels are low on a PCB and offer suggestions for solutions.

Power Integrity (PI) Analysis Option

Power voltage drops related to advanced semiconductor technologies have been increasing, and countermeasures for suppressing undesirable electromagnetic waves caused by IC malfunction have been gaining attention.
This function allows you to verify capacitor location, number of pieces, and capacitance value in order to suppress this problem.
