渐近波形评估（AWE）为线性RLC电路响应近似提供了广义方法。 RLC互连模型可能包含浮动电容器，接地电阻，电感器，甚至线性受控源。响应的瞬态部分通过与初始边界条件匹配和与低阶Q-Pole模型的确切响应的第一个2q-1矩匹配。对于RC树模型的情况，一阶Awe近似将减少为RC树方法。 >
Asymptotic waveform evaluation (AWE) provides a generalized approach to linear RLC circuit response approximations. The RLC interconnect model may contain floating capacitors, grounded resistors, inductors, and even linear controlled sources. The transient portion of the response is approximated by matching the initial boundary conditions and the first 2q-1 moments of the exact response to a lower-order q-pole model. For the case of an RC tree model, a first-order AWE approximation reduces to the RC tree methods. >
