Override a VerilogA parameters module while in tran Analysis.

Hi Everyone

I Want to change 3 parameters in-sided a Verilog A module while in tran Analysis this change is triggered by the cross event every time  the voltage across 0V.

my parameter's new values are stored in a parameters file that produces in Matlab.
how to connect this file with the transition analysis so whenever a crossing the 0V new values update to the parameters from the next index.

here is the event

@(cross(V(P,N) - 0, +1))
begin
x=xnew;
y=ynew;
z=znew;
index=index+1;
end

here is a sample of the data file

Thanks
