Hi All,
I am using PSPICE to get the nonlinear Memristor model simulation. A part of the SPICE Model is as follows:
But when running ,I get an error "Missing or invalid expression" not recognizing I(plus,minus) ,which is the current of the VCCS Gmem.
So how to solve such problem? Thanks
I am using PSPICE to get the nonlinear Memristor model simulation. A part of the SPICE Model is as follows:
Code:
Gxpos 0 x value={stp(-V(x)+lim_max)*stp(V(plus,minus))*((V(Plus,Minus))^q)*f(V(x),I(plus,minus),p)}
Gxneg x 0 value={stp(V(x)-lim_min)*stp(V(minus,plus))*((V(Plus,Minus))^q)*f(V(x),I(plus,minus),p)}
Cx x 0 0.00008 IC=0.15
Raux x 0 0.01T
Gmem plus minus value={(((V(x)^n))*b*sinh(a*V(plus,minus))+c*(exp(g*V(plus,minus))-1))}
.func f(x,i,p)={1-(x-stp(-i))^(2*p)}But when running ,I get an error "Missing or invalid expression" not recognizing I(plus,minus) ,which is the current of the VCCS Gmem.
So how to solve such problem? Thanks
