sweeping nport file name with ADEXL

RoiNaor
Hi, I saw a thread on that before but the answers were not very clear. I want to sweep the filename of a nport cell. lets say the filename is called sp1.s2p. now i have 100 different files sp1.s2p sp2.s2p ... sp100.s2p. I want to sweep them all using a global variable. The first thing i did is define the file name as a variable in the "Additional parameter list" (file=filename) then i added a global variable called filename = "path/sp1.s2p" this works well. the problem is how i create a second var that will concatenate inside the filename? Is there a better way to do that? Thanks

  • Specify an include path (as described in https://community.cadence.com/cadence_technology_forums/f/38/t/36287). If this is not what you need, you have to describe your goal in a clearer way.

  • In addition to what Frank mentions, if your filenames are regularly named (e.g. sp1.s2p, sp2.s2p, sp3.s2p) you can arrange the sweep without having to list all the filenames - you have to be using ADE XL (or Assembler/Explorer) for this though. Here's some notes I had when looking into this a few months ago:

    There's no need to list the full path of each s-parameter file. I created an example with three files, called A1.s2p, A2.s2p, A3.s2p. The parameter was called MYFILE, and the files were in a directory called sparamFiles.

    I set the include path on the test to include the sparamFiles directory and then set MYFILE in the ADE XL Global variables to be:

    "A1.s2p","A2.s2p","A3.s2p"

    and it works file. So no need for full paths.

    Now, if the files are regularly named, you can take advantage of the fact that Global variables in ADE XL are evaluated using SKILL. So, create a second Global variable called n, with value 1:1:3 (1 to 3 in steps of 1). Then I set:

    MYFILE: sprintf(nil "A%d.s2p" n)

    Regards,

    Andrew.

  • thank you Andrew! worked pretty well!
