Cadence Sigrity 3D-EM v19.00.000  一款專業好用的仿真設計軟件

了解新的雲就緒清晰度三維解算器如何讓您優化設計，以進行真正的三維系統分析。這種電磁（EM）求解器解決了芯片、封裝和pcb上復雜的三維結構，創建了用於信號完整性（SI）、功率完整性（PI）和電磁兼容性（EMC）分析的高精度S參數模型。

這種新的電磁解算器提供高達10倍的電磁模擬性能，具有無限的容量和金標準精度。加速IC封裝和PCB電源完整性和信號完整性分析以及電磁接口（EMI）/電磁兼容性（EMC）分析，CadenceSigrityPowerSI3D電磁提取選項三維（3D）全波和準靜態電磁（EM）場解算器使用模型簡化技術提供S參數模型提取。為了獲得復雜三維結構的精度，雲就緒工具采用了自適應有限元網格（FEM）細化技術。

設計的標準二維視圖（左）允許選擇網絡和查看單個或組網絡。通過遍歷所提供的工作流中的步驟，您可以對常見任務遵循可重復的流程。設計的三維視圖（右側）允許您通過過孔跟蹤連接，並可視化互連之間的關系，而只有二維視圖是不可能的。

PowerSI3DEM選項包含一個用於創建、編輯和導入三維實體模型以進行三維電磁分析的三維機械CAD圖形用戶界面。您可以從流行的MCAD格式（如Acis、IGES和STEP）以及CadenceAllegro和Sigrity格式引入設計數據。3D機械部件易於用參數化和方程表達式創建，以允許建模靈活性和仿真優化。

除了許多其他功能外，PowerSI3DEM選項還使您能夠創建用於改進的時域瞬態分析的模型，這要歸功於其強大的低頻調節算法，該算法可為您提供低至100Hz的穩定和準確的解決方案。PowerSI3DEM選項具有工作流驅動的用戶界面和基於組件的自動端口生成和分組，使您使用起來相對容易。

準靜態提取器的運行速度比全波技術快得多，但會做出某些假設（即電場和磁場相互獨立）。它可以快速生成由電阻（R）、電感（L）、電容（C）和電導（G）組成的互連模型結果。
