ads momentum examples spiral
Hello,
I am trying to simulate the spiral inductor using ADS momentum tool (enclosed is the project file that I am talking about) by using MRIND component as starting point and added two port at each end of the inductor and added parameter n in the layout component parameter and created layout component successfully.
Next, started creating AMC model (advanced model composer) and in the model parameters tab enters freq's from 1 to 20 GHz and in the layout parameters tab selected discrete list as the sweep type and gave 2,3,4 values for n. So, while creating the AMC model it gave me the following error:
The model for the layout component is not found in the modeldatabase, a new model is generated for the requested parameters values.
Momentum simulation error.
Please verify substrate and layout, and try single Momentum simulation.
And while simulating I am getting following error:
Inversion of singular matrix encountered.
I also tried simulating other spiral inductor design (I did not attach this project) by using the spiral_ind component from the designkit library but I did not succeed which gave a different error:
Singular matrix at row 184.
So, is there any step that I am missing out in these designs? Could anyone please help me out in overcoming these errors? I really appreciate your great help.
Thanks in advance!
