PollexのPCB-level EMI DFEについて
こんにちは皆さん。 松川と申します。 題記の件2024/12/04にFekoに関するセミナーを受講しました。 その際資料のなかで以下が示されました。 使用によればGNDのスリットについてその際が示されています。 通常このようなスリットはアナログGNDとデジタルGNDを分割し その影響を受けないようにすることに用いられつと認識しています。 種々の情報からPollexではクロック信号のようなデジタル信号以外 電流分布は解析できず、Fekoへのデータエクスポートもできないと 理解しています。 上記の資料は正しいのでしょうか？認識が違えばご教授頂けますと 助かります。

PCB-level EMI checking with PollEx DFE
I was told by a Japanese distributor that Pollex cannot calculate the PCB current of analog signals. Looking at the top right of Page42, the difference in radiation noise due to the presence or absence of a GND slit is shown. In the PCB on the top left of Page42, it appears that the analog GND and digital GND are probably…
