There is a behavior that does not make sense about behavior power.
First, on the left of this image, the behavior power supply is set to “V=sin(2PIfm*time)”.
With fm and ma set as parameters, the simulation completes as usual.
However, when I set “V=masin(2PIfmtime)” with the ma parameter in the behavior power supply as shown in the right side of the image, I get the following error…
”””
Unresolved parameter: “MA”

Fatal error: Missing expression in B-source B1
”””
I wonder why ？？？？？？？
Anything you can do to help me, I will do.
