EMI Suppression Support Tool for PCB
EMIStream is an EMI suppression support tool developed by NEC that can decrease undesirable EMI generated from PCB at an early design stage. EMI Design Rule Check scans your board against 15 rules and lists errors in order of priority, allowing time-efficient noise countermeasures. Power/ Ground Resonance Analysis shows you the hot spots on the board, enabling optimized capacitor placement to reduce resonance.
Major electronics manufacturers worldwide, including NASA, are using EMIStream to significantly decrease the time and cost spent on the design and evaluation process.

What is 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.
EMIStream Key Functions and Options
EMI Rule Check
EMIStream was developed by engineers at NEC 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.
