Default Help with ECF80 spice model

I've got some trouble to turn those lines into a working LTspice model :

* ecf80t macro model
.subckt ecf80t P G K
koren8(0.08514807115,0.02125688214,2.432606355,18. 12988992,-515.1539346,47.41376622,32.41199296,1.230822006)
.ends ecf80t

* ecf80t CircuitMaker model
.subckt ecf80t P G K
Bp P K I=(0.08514807115/1.0e3)*uramp(V(P,K)*ln(1.0+(0.02125688214)+exp((2. 432606355)+(2.432606355)*((18.12988992)+(-515.1539346/1.0e3)*V(G,K))*V(G,K)/sqrt((47.41376622)^2+(V(P,K)-(32.41199296))^2)))/(2.432606355))^(1.230822006)
.ends ecf80t

Could someone explain me how to proceed ? Thanks a lot
