W8614EP 模型建構軟體(MBP)可靠性模組 MOSRA – TMI 包括用於 MOS 可靠性分析(MOSRA)和 TSMC 模型介面(TMI)老化模型的萃取軟體套件。
MBP 可靠性模組為 HSPICE 的內建 MOSRA 模型提供了萃取環境,可模擬包含熱載波注入(HCI)和偏壓溫度不穩定性(BTI)在內的老化效應。如此一來,使用者可評估元件在真實工作環境中效能逐漸下降的情形。
內建 MOSRA 模型包含兩個層級,分別為第 1 級和第 3 級。這兩個層級之間的差異,請參見下表。
MBP 2019 版軟體新增了 MOSRA 第 3 級模型萃取軟體套件。基於腳本的萃取流程支援全自動執行,並可加以客製,如下圖所示:

這是擬合結果的螢幕截圖:

除了 MOSRA,MBP 可靠性模組亦支援 TMI 老化模型產生。TMI 是採用 C 語言開發的建模 API,支援標準小型模型的擴展。使用者可量測元件效能逐漸下降的情形,並評估 40nm 或更低製程的應力效應。
