Mentor Graphics Launches iSolve SAS and Verification IP Solutions

Mentor Graphics Veloce Emulation Systems

Mentor Graphics introduced iSolve SAS and SAS transaction-based verification IP (VIP) solution. iSolve SAS is a plug-and-play hardware interface to the Veloce family of hardware emulators. The VIP solution delivers both a simulation environment, using the Questa verification platform, and accelerated simulation environment using the Veloce hardware for the verification of SAS Gen2-compliant devices. Both solutions are available now for deployment at customer sites.

Mentor’s new hardware and software solutions accelerate the verification of Serial Attached SCSI (SAS) second-generation (Gen2) products, having speeds up to 6Gbps. The verification solutions help designers test their 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.

iSolve SAS provides a cost-effective and efficient solution to verify new SAS Gen2 target devices with their software drivers in a SoC design. In addition, 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. The Gen2 solution is also fully compatible with older Gen1 speed devices.

Mentor’s VIP solution generates the appropriate stimuli for the Design-Under-Test (DUT), passing packets, or transactions, of protocol data for tests. The VIP solution 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 Gen2 SAS VIP is also fully compatible with Gen1 speed devices.

The new SAS products deliver use modes with traditional in-circuit emulation (ICE) and high-performance, transaction-based simulation or acceleration. When combined with Questa and Veloce2, the latest-generation emulator from Mentor, the SAS products deliver high-performance and easy-to-use system verification for developing SoCs containing SAS Gen2 devices, without compromising delivery schedules.
