ad温度怎么设置

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.这是仿真后提示的问题，意思都明白，就是不知道在哪里设置温度
