As computer processor chips grow faster and more complex, they are likely to make it to market with more design bugs. But that may be OK, according to University of Michigan researchers who have devised a system that lets chips work around all functional bugs, even those that haven't been detected. Firms such as Intel find functional bugs by simulating different scenarios, commands and configurations that their processor might encounter. Bugs only show themselves when they're triggered by...
