When the Chips are Down, How Do You Know They Work?
Design How-To  
1/29/2004   Post a comment
Today's VLSI design companies are all trying to grab a big slice of the pie when it comes to the complex chip designs of tomorrow. Getting a piece of the action is great—but these companies have to understand that a complex design, no matter how cool, won't make it to silicon unless the company can verify its design—beyond the faintest doubt. And, judging by results, it is not certain that this is, in fact, the case, with headline examples of re-spin and over-run clear in the mind.
