S-Parameter Testbench

Hi. I'm currently encountering Error:['untitled1/Configuration2/Solver Configuration', 'untitled1/S-Parameter Testbench/Configuration/Solver Configuration', 'untitled1/Solver Configuration']: Multiple Solver Configuration blocks connected to Physical Network. Each physical network must be connected to exactly one Solver Configuration block.

I would like to use S-Parameter Testbench after exporting the Simulink model from RF Budget Analyzer but I can't figure out how to fix the connection.

Please help me resolve this issue. Thanks

Hi Christina,

The error you are getting indicates that more than one ‘Solver Configuration’ blocks are connected to a single physical network. Each physical network requires exactly one ‘Solver Configuration’ block to be connected to it. You may refer to the following documentation:

https://www.mathworks.com/help/releases/R2024a/simscape/ref/solverconfiguration.html#:~:text=Each%20topologically%20distinct%20Simscape%20block%20diagram%20requires%20exactly%20one%20Solver%20Configuration%20block%20to%20be%20connected%20to%20it

I assume that you have already populated configurations in the ‘Configuration2’ block.

It seems that the ‘Configuration2’ block in the model already has a ‘Solver Configuration’ internally. So, you may consider removing the ‘Solver Configuration’ block connected in the model.

Additionally, the ‘S-Parameter Testbench’ block uses internal configuration block by default. This may be removed by unchecking ‘Use Internal Configuration block’ setting in its block parameters dialogue.

You may read more on these blocks from the documentation links given below:

• S-Parameter Testbench: https://www.mathworks.com/help/releases/R2024a/simrf/ref/sparametertestbench.html

I hope this helps!
