At a recent IC seminar, I overheard some attendees talking about the 'EDA-On-Tap' program, which is a new fee subscription-model for some of Cadence's product-line. Unfortunately, when I went to Cadence's website, and did a search, I found no mention of the program anywhere. In fact, even after doing a google.com search, I could only find oblique references through online resumes of its past developers. Is there a minimum/maximum purchase limit through EDA-On-Tap? Do you need to be a regular maintenance (perpetual) licensee of another product to participate in the program?
