瞬态仿真

网友回复:

没有用过，不太了解，不过你可以尝试一下，多看看help

不知你说的不可以仿真是结果不对还是仿真器被错误中止
P-1tone是功率源，
建议你用V－1tone或I－1tone加到你的管子上，再说你仔细看看HELP的文字吧
This power source is defined by its frequency, power, impedance, and linear modulation. It can be used in all circuit simulations.
For ac analysis, only Z and Pac are used--all other parameters are ignored. When frequency conversion ac analysis is performed, the Freq parameter is used to set the frequency of the source. For harmonic balance and envelope, the Freq parameter identifies the closest analysis frequency. If the frequency is not close enough, a warning is generated and the source generates no signal for that analysis. In the envelope analysis, the frequency difference can be up to 0.5/timestep and the given frequency is still properly generated.
This source can also be used in transient analysis to generate an arbitrary waveform at the specified carrier frequency. The time domain output waveform of P_1Tone is a cosine. In order to get a sinusoidal waveform, set P=polar(magnitude, -90), where magnitude is the power magnitude. The transient waveform amplitude is affected by the load termination such that, for a matched load this amplitude is scaled by 1/2.

仿真时被错误信息中止，总是提时说矩阵错误，不知道是什么原因，我看过帮助了
不过试了一试，还是有好多源不能用，现在在用谐波，但是效果没有瞬态好

网友回复:

我的谐波仿真用不了，报错：
Simulation / Synthesis Messages

是怎么回事啊？我用的是2005a，有人遇到过这个问题吗？

期待高手指点

网友回复:

我冒昧说一句，因为我用cadence是由也有个相似的报错，难道是 licensed的问题？
