How to pass parameter in a subcircuit and received in subcircui

[prajapatisantlal]

I want to initialize voltage across capacitor with a parameter in a subcircuit during SubCircuitElement creation. I simulated my subcircuit in pyspice. Below is netlist and error.

NETLIST:-------------------------

.title memristor in PySpice .subckt memristor TE BE x .ic V(x)=x0 Cx x 0 1 Gx 0 x TE BE 1 Bb1 b 0 v={(1e-6+180e-6*V(TE,BE))*V(x,0)} Gmem TE BE b 0 1 .ends memristor X1 TE BE x memristor x0=0.01V Vinput TE 0 DC 0V AC 1V SIN(0V 1V 1Hz 0s 0Hz) R1 BE 0 0.1Ohm .options TEMP = 25C .options TNOM = 25C .end

ERROR:------------------------

‘x0’ is parameter value

Any one please Suggest any idea or give example. Thank you.
