Mystery Guy, I'm afraid you've missed the point. All tools have bugs and issues - it's just a matter of degree. We're talking about a relatively small market that is using some very complex tools. Throw in the fact that the problem is constantly getting more complex (speeds go up), and it should be common sense that bugs and problems are going to be an ongoing issue. As others have said, using these tools requires experience and good judgment. We've seen issues that could be reproduced, and issues that couldn't be reproduced - with any tool you care to name. If you're looking for meaningful input, I suggest you name the application you're designing to (for instance, DDR2-SDRAM/533 MT/s) - then ask people whether they've been successful with a particular tool and if they know of any "gotchas" should be on the lookout for. Asking "has anyone heard of problems" via an anonymous request just has a cloak-and-dagger feel to it. This is engineering, not drama. Happy Thanksgiving to all who celebrate it, Todd. =20 Todd Westerhoff High Speed Design Group Manager Cisco Systems 1414 Massachusetts Ave - Boxboro, MA - 01719 email:twesterh@xxxxxxxxx ph: 978-936-2149 =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D =20 "Always do right.

SpecctraQuest is GOOD/BAD Tool for Board Level Simulation < 400 MT/s??? Please forgive the anonymous aspect of the request. I do not wish to steer the result by way of company name/individual's name, nor do I wish to embarrass the originator of the request. This is not an attempt to tarnish any tool maker's reputation, and my apologies if the request comes across that way. There is no intended assertion that a problem exists by way of the request itself. =20 I am asking the SI experts of the world if anyone has experienced issues with SQ that would lead to concern about the results. It may be the case that the answer is no and experts have been using this tool quite extensively, in which case a strong assertion to this effect would be in order. I am not saying that either answer is right or wrong, but the request was intended to illicit candid opinions from the experts. =20 If you have seen an issue that can be reproduced/confirmed, please feel free to pass along directly if you wish to remain anonymous about this topic. =20 Thanks for your patience. =20 Ray Anderson <ray.anderson@xxxxxxxxxx> wrote: =20 The message posted anonymously to the list earlier today=20 =20 (deleted) Regards, -Ray Anderson (si-list admin) -----Original Message----- From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx] On Behalf Of mystery guy Sent: Tuesday, November 22, 2005 2:06 PM To: si-list@xxxxxxxxxxxxx Subject: [SI-LIST] HELP!!
