PCB設計／ICパッケージ設計: (P)SpiceItUp: PSpice A/DでISO 7637-2標準パルス2aの生成

SPB Japan

多くの場合、業界標準に準拠したデバイスのテストに使用できる標準的なパルス波形を作成する必要があります。その一例として、回路図の設計段階でISO 7637-2トランジェントをシミュレーションする方法があります。これにより、電磁両立性（EMC）試験の前に問題を発見することができ、設計時間やコストの増加を防ぐことができます。 PSpice® A/Dでシミュレーションを行うと、自動車や家電製品などのテストや解析に使用できる電子回路の単純なインパルスや繰り返しのパルス波形を生成することができます...

PCB設計／ICパッケージ設計: ASCENT: Allegro System Captureでのデザインのリユース

SPB Japan

今回は、ロジカルデザインとボードの作成に長い経験がある方にお伝えしたい内容をブログにしました。ほとんどの場合、製品やデザインの新規作成において、すべての部品やモジュールを一から作成する必要はありません。ほとんどの標準部品はリユース(再利用)され、時には回路とロジックの大部分についてもそのままリユースされます。このようなリユースは、新しいデザインをよりスピーディに開始するのに役立ちます。既存のデザインを起点にし、あるいは既存のデザインに部分的な追加や要件に応じたカスタマイズを行えば、新たな初期デザ...

Digital Design: Glitch?? Do Not Let It Impact Your Design Power!!

Neha Joshi

A glitch, although, is an unnecessary signal transition in your design. But its impact can be tremendous. And yes, glitch contributes to glitch power as well. It can affect the power dissipation by many folds as it could be a significant part of your dynamic power consumption.

So even though it is unnecessary but you must identify the glitch power!!

How to analyze glitch power?

Relax!! And leave glitch for Joules RTL…

カスタムIC／ミックスシグナル: Virtuosity: 分散型ファームにおけるリソースの最適な利用

Custom IC Japan

読者の皆さん、こんにちは。ジョブやシミュレーションを実行するために、どれくらいのリソースが必要なのか、誰しも疑問に思ったことがありますよね。これは難しい問題で、一般的には皆さんが考えている上限を確保することになります。ただし、予定した分のリソースを使用しない場合もありますので、その場合、リソースを最適に使用できないことになります。あるいは、予定したリソースの制限を超えたために、ジョブが停止または中断されたというシナリオもあるかもしれません。そのような場合には、ADE AssemblerのLS...
