Altera Nios II Processor Model Delivered By Imperas

Open source simulation model enables Altera customers to more easily validate and debug Nios II embedded software

San Jose, Calif., October 22nd, 2013—Imperas Software Ltd. (www.imperas.com), founder of the Open Virtual Platforms™ (OVP™) consortium, today announced the availability of the Altera Nios II embedded processor OVP model. Jointly developed by Imperas and Altera, this open source model will enable a high-performance development environment for Nios II embedded software.

The OVP Fast Processor Model of the Nios II may be configured at start-up to match the intended behavior of the actual FPGA component, but will execute significantly faster than real-time. This allows embedded software to be tested more rigorously and earlier in the design process, accelerating complex software development cycles.

“Imperas led formation of the Open Virtual Platforms consortium to improve the embedded software development experience,” said Simon Davidmann, CEO of Imperas. “With Altera, we have taken an important step today by providing designers with a high-performance model of the Altera Nios II processor, executing many times faster than other development offerings to enable the most comprehensive software verification solution available.”

Altera discuss successful use of Imperas tools to find complex OS bugs

At the June 3, 2013 North American SystemC User Group meeting as part of the Design Automation Conference 2013 in Austin Texas, Victoria (Vicki) Mitchell of Altera presented a paper titled: Embedded Software Dynamic Analysis: A New Life for the Virtual Platform.

The presentation introduces the Software part of HW/SW co-design, with the issues of Code Safety and Security being addressed and how Dynamic Analysis using simulation and virtual platforms can address them. It continues with Software Analysis by using a platform modeled with OVP and using the Imperas tools shows examples of how bugs were found in the use of Linux and uC/OS-ii. The presentation concludes with the conclusion that the use of virtual platforms and dynamic analysis provides safe and secure code for embedded systems.

Imperas launches multicore software development tools

Peter Clarke      EETimes     May 20th, 2013

LONDON – Imperas Software Ltd., a vendor of virtual prototyping, high-speed instruction-accurate modeling and simulation software, is offering its second generation of multicore software development tools to sit on top of its platforms.

The Imperas product offering is divided into the Developer range of tools and the more fully-featured Multicore Software Development Kit (M*SDK). The software debug is based on so-called ToolMorphing technology in which debug tools and hardware models are merged in the same execution stream and compiled in a just-in-time manner. This produces faster than real-time execution performance improves verification throughput, Imperas claims.
