Mentor Graphics has announced hardware and software for testing Serial Attached SCSI (SAS) Gen2 devices integrated on their System-on-Chip (SoC) designs, and develop and test their software drivers and applications prior to silicon being available.
The product called iSolve SAS is a ‘plug-and-play’ hardware interface to the Veloce hardware emulator from Mentor. An emulated SoC containing a SAS initiator device, such as Host Bus Adapter, can be connected via the iSolve SAS solution to a full-speed SAS disk drive for testing with real target hardware.
SAS transaction-based verification IP (VIP) solution generates the appropriate stimuli for the Design-Under-Test (DUT), passing packets, or transactions, of protocol data for tests. The VIP solution also provides a high-level Application Programming Interface (API) to allow use with multiple test-bench environments, such as SystemVerilog and SystemC, and provides example test environments that can exercise the emulated SAS Gen2 device.
“The growth in SAS products has been increasing rapidly, and is especially important to those in sectors where large data-intensive storage is mandatory for the operation of applications,” said Eric Selosse, vice president and general manager, Mentor Emulation Division. “The challenges faced by the creators of such systems are complex, and require high-performance verification solutions to detect flaws early in the development cycle and to reduce risks. To solve these challenges, we created both hardware and software solutions for the verification of SAS Gen2 products. These products provide flexibility and ease-of-use, including the configurable test models that our customers require for pre-and post-silicon testing.”
