Synopsys officially rolls out a silicon core for PCI Express 2.0 Monday (April 28), claiming the 5 GHz technology is beginning to get attention from designers. The news comes at a time when experts say the industry is moving at a relatively slow pace down the Express road map.

Synopsys is supplying silicon intellectual property for the physical layer, controller and verification portions of the Express 2.0 spec.

"Other companies tend to have one or two of the components but not all three," said Navraj Nandra, director of mixed-signal IP at Synopsys. "When you have to work with more than one silicon IP vendor, it gets complicated," he said.

The IP comes in versions supporting four and eight lanes of Express, which Synopsys believes are the most common configurations. However, at least one switch maker is creating a 32-lane Express switch chip using multiple copies of the core.
