Passing file name parameter to vpwlf source

k0stas

Hello,

I have a collection of PWL files and I would like to test my ciruit with them. Is there a way to pass the filename of the PWL file to the vpwlf source usiing Parametric Analysis?

I have tried using pPar("filename"), which successfuly allows passing of the variable through the ADE, however, using the Parametric Analysis tool in Parametric Set mode gives the error:

*Error* The sweep specification for variable "pwlFile" is invalid because 'Bad inclusion value "file1.pwl".'

Ideally, I would like to be able to use a fixed filename prefix, like "/home/mydir/pwlfile" and concatenate (or insert) a number to it, so I could run, e.g.,  "/home/mydir/pwlfile0" and "/home/mydir/pwlfile1" by sweeping a design variable from 0 to 1, which gets concatenated to the prefix. Based on experimentation, the pPar() method seems to require that the entire field is parameterized, so setting the vpwlf file name field to "/home/mydir/pwlfile/"pPar("fileNum") does not work.

Any suggestion for a way to do this is greatly appreciated.
 
Thanks,
Kostas
