... as well as a major source of inspiration. As in many other fields, it never hurts to know what the competition is doing. I'm not an analog expert by any means. So when I go to simulate a simple transistor circuit, for instance, it is much less painful for me to choose '2N4401' from a list in LT-Spice, than to extract all of the Spice parameters from a datasheet to feed into *spice or gnucap [*]. Unfortunately, when people are evaluating free software, it's the initial impression that counts. And if it's a question of freedom versus usability, there are a lot of people who will go with usability. [*] Forgive me if I overlooked a collection of off-the-shelf device models in gnucap-- I'm using the version from Debian unstable, and it already looks like there are some pieces missing from the package. On the other hand, there's no mention of them in the manual. -- Charles Lepple http://www.ghz.cc/charles/
