Hi, I have a suggestion if a) you're having trouble with an S-param file and b) you are able to share it. Recent examples (potentially) include the threads: [SI-LIST] Re: Simulating s-parameter model in HSPICE - DC Data Point Issue? [SI-LIST] Causality Here's how to share a large file. If you go to a site like http://drop.io <http://drop.io/> you can upload the file easily and gratis (if it is 100MB or less), and get a short link to post in your email to si-list. Of course, if the data is propriety then you won't want to do this.
