4. ARESARES S.-P. YongIntroduction(2/2) SPICE : Simulation Program with Integrated Circuit Emphasis Hspice 是一個電路模擬軟體，用來模擬所設計電路的行 為及功能特性。 Hspice 係以電晶體、二極體、電阻及電容等各種元件模 型為基礎，透過數值方法來計算電路各節點的 電壓、電 流變化。 對於非線性的電路系統， Hspice 是在計算近似解， 所得 結果的正確性和元件模型、演算法則有密切關係。 Hspice 主要提供穩態、暫態及小信號頻率響應模擬 ，使 用者需依所設計的電路種類自行規劃分析的指令及相關的 輸入。
