can AEL(analog Expression Language) evaluate strings?

karis86

I am doing an analog simulation with spectre and want to change 2 voltage sources (A,B)  with a simple parameter. My voltage sources are pwl type and need a file as input.

I have lets say 3 states (0,1,2). The files I have to load are looking like this

voltageA_0.vcsv

voltageA_1.vcsv

voltageA_2.vcsv

voltageB_0.vcsv

voltageB_1.vcsv

voltageB_2.vcsv

Now I want to load both voltage files with one parameter param. I thought I can write a strcat in the filename promt like this: 

strcat(nil "voltageA_%f.vcsv" param) for voltage source A

strcat(nil "voltageB_%f.vcsv" param) for voltage source B

But this will not be evaluated by AEL before netlisting.

What can I do?
