hello
i've got one problem in modelling capacitor
i wrote
I(vp,vn) <+ ddt(c*V(vp,vn))
but c=25*limexp(-23.3*V(vin_p,vin_n))
the error message is
line 16: Error: An operand dependent on the output of a dot() operator (dynamic expression) can not be used in a multiplication operation when the other operand is dependent on a probe or the simulation time. Consider using a node to hold the dynamic expression and probe this node in the multiplication operation. See also the section of the SpectreHDL reference manual describing "Time Derivative Operator".
i am beginer and don't understand the proposed solution starting with consider
can you explain me how to fix it?
regards
