Warning detected by hpeesofsim during TRAN analysis `SP1'.
COMPONENT `X4_LNA_schematic_13_1':
Simulator uses frequency lower than frequency range of Momentum model. The S-parameters are extrapolated.
Warning detected by hpeesofsim during TRAN analysis `SP1'.
COMPONENT `X4_LNA_schematic_13_1':
The model for the Layout Component is not found in the ModelDatabase, a new model is generated for the requested parameter values.
Warning detected by hpeesofsim during TRAN analysis `SP1'.
COMPONENT `X4_LNA_schematic_13_1':
The model for the Layout Component is reused from the ModelDatabase.
Warning detected by hpeesofsim during SP analysis `SP1'.
The simulation temperature (25.0 C) is not the same as the IEEE standard
noise temperature (290 K or 16.85 C) in the noise analysis `SP1'.
If the simulation temperature is not equal to the IEEE standard temperature,
then the loss and the noise figure will not agree for a passive circuit.
The `Temp' parameter on the Options item can be set to 16.85 C to
eliminate this warning message.
仿真几个小时之后给出这个提示，仿真结果S21为负值，噪声到70多最小噪声也是70多，请教是什么地方错误造成的，非常感谢。
你确定线都连好了?
我最近仿真也总是出现 这个The model for the Layout Component is not found in the ModelDatabase, a new model is generated for the requested parameter values不知道什么原因啊，坐等高手解答
我也出现问样问题了，望解答
