ADS版图联合仿真参数调节求助

如题，错误截图如下，请高手指教

在tuning 之前，最好先做一次参数扫描。如果你不嫌弃线性插值的精度差的话，去 layout component 属性中把 允许线性插值勾中。
Once you create a Layout Component, you can simulate it over any range of values. However you cannot start TUNING it, until a Model Database has been created.
The way real time tuning works with EM cosimulation is that it will only tune within the range that has already been simulated. During tuning, ADS can interpolate using newer points between the existing ones, but it CANNOT extrapolate outside the simulated range.
So to perform tuning, its best to get some simulation points for your desired range. To do this, its best to set up a Parameter Sweep simulation over the desired range in the Schematic window and then run that. Once this simulation is finished, the Model Database should be available. Now you can de-activate the Parameter Sweep and perform tuning on this model.
