Mentor Graphics Corp. unveils a set of protocol transactors for the Veloce hardware emulation platform that are said to enable the use of stimuli generated by modern simulation test benches including SystemVerilog/OVM and UVM, SystemC and C-based environments, and apply them to the design-under-test (DUT) running in the Veloce hardware.

The transactors allow engineers to stress-test a DUT that includes one or more protocol interfaces on their SoC at orders of magnitude faster than simulation, touted Mentor Graphics. Since the connection between the test bench and the Veloce transactors are at a transaction-level, rather than signal interface, a high level of performance is delivered, added the company.

The Veloce transactors provide protocol solutions for ARM's AMBA AXI, AHB and APB standards, USB, PCI Express, Serial Attached SCSI (SAS), SPI, I2C and audio standards including I2S. The ability to use the same test bench in both simulation and emulation leverages test bench development across the two platforms and accelerates design regression testing by hundreds of times over simulation, Mentor Graphics claimed.

The Veloce transactors are used as an essential part of the strategy for verifying SoCs containing multiple protocol interfaces on chip. Users can develop test benches in one of several supported high-level verification (HVL) environments, and then seamlessly interchange between simulation and acceleration. This delivers an effective and productive environment to develop new, leading-edge SoCs and accelerates delivery schedules.

The Veloce transactors can be used with both transaction-based acceleration and traditional In-Circuit (ICE) modes of operation. The ability to mix and match ICE mode with high-performance transaction-based acceleration demonstrates the Veloce product's key benefit as a software-configurable verification platform.

The solution is available for deployment at customer sites, effective immediately.
