EMI Design Rule Check

EMIStream EMI Design Rule Check

15 EMI Design Rule Checks

EMIStream’s 15 rule checks are boiled down from a huge amount of historical know-how about EMI suppression countermeasures and have been verified by NEC Laboratory and local and overseas university researchers with a logical background. In this way, EMIStream utilizes the most valuable EMI design rule check for real-world PCB design.

EMIStream AI Model

New AI Feature

You can narrow EMI check results down to significant errors using an AI that has learned EMC Experts’ know-how of design review. This function allows you to shorten the review time, and suppress variations in design quality.

EMIStream EMI Design Rule Check Filter

Error Filtering Feature

This function allows you to filter errors and hone in on critical problems relevant to your design. The Design Rule list lets you look at certain rules of your choice as well as narrow down the frequency range (of the nets). The Error Point list is organized by number of error points, which also gives you the frequency range columns. You can customize the frequency and error point ranges.

EMIStream EMI Design Rule Check

EMI Check Report Generation

You can export EMI Check results in an Excel format. It displays the error, the location on PCB, and advice on how to fix the problem. This is very useful when sharing results with fellow engineers or an outsourcing design bureau. You can edit comments and customize the report to fit your needs.

EMIStream Estimated Radiation

Estimated Radiation Display

The frequency spectrum chart display of estimated radiated electromagnetic field allows you to see the problematic frequency range at a glance. The Expert Option lets you to set the IC rise time and damping/termination resistor value for individual nets and override the global value that is set in the parameter. By putting in specific parameters for nets, you can get more accurate results.

EMIStream Cross Probe

Cross-Probe

Now EMIStream got cross-probe feature between schematic capture and PCB layout. Users can easily switch between schematic and layout to identify EMI errors.
