Mentor Graphics Corp. announced the availability of two new iSolve speed adapters from its family of emulation products supporting the USB and PCI Express industry standard protocols.

The new iSolve speed adapters boost productivity of an SoC or asic design by connecting it from a Mentor Graphics emulator to a full-speed PCI Express or USB bus for in-circuit system-level verification, said the press release.

The new speed adapters provide a rapid path to system verification by creating an environment that combines real USB or PCI Express hardware and applications software, together with the SoC or ASIC design in a hardware emulator, explained Mentor. As a result, corner-case bugs in hardware and software can be identified and fixed. Design teams can then address important interoperability and compliance issues that occur with new and evolving bus protocols. The iSolve solutions give designers the confidence in running billions of real world cycles on their SoC design before tape-out, meeting customer delivery schedules and financial returns, the company added.

Unlike other solutions, the iSolve speed adapters allow "real-world" application stimulus for accurate functionality testing since the customer's design can directly plug into a PCI Express or USB bus. "Customers verifying USB or PCI Express protocols will realize increased productivity gains," shared Eric Selosse, VP and GM for Mentor's Emulation Division. "The iSolve solutions provide a clear competitive advantage to our customers by allowing them to deliver products that meet today's rigorous compliance requirements and time-to-market schedules."

Key features of the adapters include a speed adaption between high-speed (480Mbps) or full-speed (12Mbps) USB serial bus and the emulator parallel UTMI bus; easy integration of third-party testers to fully validate USB compliance of the design under test (DUT); and the capability to allow verification of embedded software using industry-standard debuggers.

Based on Mentor's Inventra PCI Express intellectual property, this new solution consists of a two-port PCI Express switch with two endpoint cores. Users can apply either a "forward" or "reverse" speed adapter to verify an endpoint or a root complex design, respectively.
