OXFORD, United Kingdom, November 13, 2012 – Imperas, which through Open Virtual Platforms™ (OVP™) is the de facto source for fast processor core models, announced today the OVP virtual platform of the Renesas Electronics V850E PHO3 device.  This virtual platform is available today from Imperas, and will soon be available from the OVP website (www.OVPworld.org).  As with all OVP models, the V850E PHO3 virtual platform is available as an open source platform, but requires the OVPsim™ simulator to run.  Imperas will be demonstrating the V850E PHO3 at Embedded Technology 2012, November 14-16 in Yokohama, Japan.

Imperas will also be demonstrating the Multiprocessor/Multicore Software Development Kit (M*SDK™) at Embedded Technology 2012. M*SDK includes advanced tools for multicore software debug, test and analysis such as OS and CPU-aware tracing (instruction, function, OS task, OS event), hot spot profiling, code coverage and memory and cache analysis.  These Verification, Analysis and Profiling (M*VAP™) tools utilize the patent pending binary interception technology, SlipStreamer™, which enables these analytical tools to operate without any modification or instrumentation of the software source code, i.e., the tools are completely non-intrusive.  The M*VAP tools require only that the OVP fast processor model be used in the virtual platform.  Since OVP fast processor models work in SystemC/TLM-2.0 virtual platforms as well as OVP virtual platforms, the M*SDK tools work in both virtual platform environments.  Imperas users have applied M*SDK tools in SystemC/TLM-2.0 virtual platforms with SystemC simulators from all the major simulator vendors plus the OSCI SystemC simulator.

In addition to the M*VAP tools, users of M*SDK can define their own custom tools using SlipStreamer.  Imperas has been helping customers by developing templates for tools to do fault injection, protocol verification, exception analysis and functional coverage.  These templates are available at no charge to M*SDK users.

“Software testing is a huge issue in automotive electronics.  By providing simulation-based tools focused on software test and development, Imperas is improving the user experience and results for Renesas processors,” said Martin Baker, senior manager, ecosystem and business management for the Automotive Business Unit of Renesas Electronics America. “By continuing to support the V850 processor core family and V850 devices, Imperas and OVP are helping expand the toolkit available to the Renesas automotive user community.”

“Renesas users recognize the importance of virtual platforms to provide more comprehensive testing of software for embedded systems,” said Simon Davidmann, Imperas CEO, and OVP founding director.  “The combination of Imperas’ advanced tools, and user-defined tools, with OVP fast processor models helps users take the next step in embedded system development.”

OXFORD, United Kingdom, October 25, 2012 – Imperas, which is a member of the ARM Connected Community, has released its models of the ARM Cortex-A15, Cortex-R4, Cortex-R4F and ARM1176 processor cores. These models, as with all OVP models of the ARM processor cores, are now available from Open Virtual Platforms (OVP). Support from OVP includes example virtual platforms incorporating the cores, with the processor core models also supported in Imperas advanced software development tools. The models, together with the OVP and Imperas M*SDK tools, will be demonstrated at the ARM TechCon conference October 31 and November 1 in Santa Clara.

The OVP Fast Processor Models and example platforms are available from the Open Virtual Platforms website,www.OVPworld.org/ARM. The new models of the ARM processor cores, as well as models of the other ARM processors including the ARM7, ARM9, ARM10, ARM11 and Cortex-A, Cortex-R, and Cortex-M families, work with the Imperas and OVP simulators, and have shown exceptionally fast simulation performance of hundreds of millions of instructions per second. The OVP Fast Processor Models include support for both the 32 and 16-bit instructions, as well as the MMU, MPU, TCM, VFP, NEON, TrustZone, virtualization and Large Physical Address Extension (LPAE) features.

“The ARM Cortex-A15 and R4 processor cores are state of the art cores, with significant complexity in and of themselves, and even more complexity when considered in the context of the SoCs that implement these cores,” said Simon Davidmann, president and CEO, Imperas and founding director of the OVP initiative. “Software engineers using advanced cores demand additional tools for debug, test, analysis and optimization, and the OVP processor core models together with the Imperas M*SDK tools provide the needed capabilities.”

All OVP processor models are instruction accurate, and very fast, focused on enabling embedded software developers, especially those building hardware-dependent software such as firmware and bare metal applications, to have a development environment available early to accelerate the software development cycle. OVP processor models employ a state of the art just-in-time code morphing engine to achieve the simulation speed. Virtual platforms utilizing these OVP processor models can be created with the OVP peripheral and platform models, or the processor models can be integrated into SystemC/TLM-2.0 based virtual platforms using the native TLM-2.0 interface available with all OVP models. The native TLM-2.0 interface enables multiple instantiations of the processor models in a single virtual platform, just as any other component would be instantiated. The OVP simulator can also be encapsulated within the Eclipse IDE, enabling easy use for software developers.

OVP also has reference virtual platforms incorporating the ARM cores, including a virtual platform of the ARM Versatile Express development board using any of the ARM Cortex-A family of models. These reference platforms are all available as source code, and are easily modified to add or change the memory and peripheral components to customize the platform as required for software development.

In addition to working with the OVP simulator OVPsim, the OVP Fast Processor Models work with the Imperas Multiprocessor/Multicore/Multithread Software Development Kit (M*SDK). These advanced tools for multicore software verification and analysis include key tools for software development on virtual platforms such as OS and CPU-aware tracing (instruction, function, task, event), hot-spot profiling, code coverage and memory and cache analysis. The Verification, Analysis and Profiling (M*VAP) tools utilize the Imperas SlipStreamer patent pending binary interception technology.

ARM TechCon is the largest conference devoted to developers of ARM-based SoCs, software and systems, bringing together users, hardware and software vendors, ARM technologists and others in the ARM ecosystem.

Imperas at ARM Techcon:  Simon Davidmann will be presenting a paper, and Imperas will have a booth in the exhibits.

OS Porting and Analysis for Dual-Core ARM Cortex-A9 Based Systems, Simon Davidmann; Wednesday October 31 10:30am

Description: Whether Linux, RTOS, or a combination, the OS and its related software are much more difficult to port, boot, and analyze in a multicore system. Using an instruction-accurate virtual platform allows use of the actual OS kernel (not a debug version), provides console messages before the console is available on hardware, and provides additional visibility into the interaction of the operating system or systems with the hardware. For example, though booting Linux on a Cortex-A9 takes hundreds of millions of instructions, it takes just hundreds of processes. When OS-aware tools enable analysis at a higher level of abstraction than just instruction tracing, the result is much more efficient bring-up of an OS. Examples of SMP and AMP systems show how virtual platforms ease OS bring-up.

Takeaway: How to simulate software on the virtual platform. OS-aware tools for virtual platforms, including process and event tracing, and analysis of context switching and scheduling.

Booth demos will focus on CPU and OS aware tools for software verification, analysis and profiling, especially for multicore SoCs and multiprocessor systems.

Using Processor Models for Software Development and Validation, Larry Lapides, Tuesday October 23, 5:15pm

Paper Abstract:

As automotive electronics systems get more complex, quality becomes a much bigger issue.  Solving the quality issue means improved testing methodologies, both for testing of individual ECUs, as well as systems involving multiple ECUs.  Virtual platforms (software simulation) provide one approach, not only for basic software testing but also adding in more advanced test and analysis capabilities like code coverage, profiling, memory analysis, fault injection and more.

This presentation will discuss the construction of very high performance (hundreds of millions of instructions per second) instruction accurate virtual platforms, and will present advanced test and analytical capabilities of virtual platforms.  Examples will be shown for using virtual platforms with Simulink/Matlab, memory analysis for a tire pressure sensor, in depth analysis of exception handling and a user-defined tool for fault injection testing.

Cooley’s CDNlive’12 Trip Report lists best papers. Fast Processor Models comes 4th

At the recent Cadence CDNlive event there were 95 papers presented and the conference attendees vote as to which papers they rate the best.

Imperas’ Larry Lapides presented a paper on Fast Processor Models for SystemC Virtual Platforms and we were surprised and pleased that it was rated 4th best paper – the event is traditionally focused on silicon design, and yes the top 3 papers were related to that. So it just goes to show that the adoption of virtual platforms is becoming more and more important.

The paper introduced why multicore/multiprocessor software development fails using old techniques, and explains that initial usage of virtual platforms with multiple debuggers and multiple windows just made everything more painful. “No wonder that more than half of current embedded design projects are behind schedule …”.

The paper discussed SystemC Virtual Platforms and introduced the Imperas OVP Fast Processor Models, how they are constructed, used, and what is available.

The paper continued by discussing the library of models ranging from all the ARM Classic thru Cortex, the MIPS full range, Renesas, Xilinx, etc, and then explored use models based on the Cadence Virtual System Platform model of the Xilinx Zynq-7000 EPP using the Imperas OVP Fast Processor Model of the ARM Cortex-A9MPx2 core. The paper concluded by introducing some of the Imperas advanced software tools.
