Second Gen of Open Virtual Platforms APIs

Imperas recently released of the second generation of the Open Virtual Platforms (OVP) APIs for building virtual platforms, additional Fast Processor Models, new models for popular peripherals, and new Extendable Platform Kits (EPKs). Open Virtual Platforms is a website for the OVP APIs, for the OVP models and platforms, for the OVPsim simulator, and for community discussion of virtual platforms on the OVP Forum. Publicly available and not proprietary, the models and platforms are available under the Apache Open Source License.

What’s new:

  • Support in the OVP APIs for unlimited hierarchy in virtual platforms
  • Support in the OVP APIs for virtualized passing of packets between peripheral models
  • ARC EM6 model
  • SPARCv8 model (developed by Friedrich Alexander University)
  • CAN, Ethernet, and USB models
  • Altera Cyclone III Nios II Linux and Cyclone V HPS Cortex-A9MPx2 Linux EPKs
  • Freescale Kinetis Cortex-M4 MQX and Vybrid Cortex-A5 MQX EPKs
  • Xilinx MicroBlaze ML505 Linux

With the ARC, ARM, and SPARC Fast Processor Models, 150 CPU models are now available. The performance for these models under a typical load is hundreds of millions of instructions per second, with peak performance of billions of instructions per second. The library of fast processor models includes models of ARM processors from the ARMv4 through the ARMv8 architecture, a complete set of MIPS models, plus models of Altera Nios II, ARC, PowerPC, Renesas, SPARC, and Xilinx MicroBlaze cores. Models are available with both C (OVP) interface and a C++ (SystemC) interfaces.

EPKs are designed to help accelerate embedded software development, debug, and test. They are virtual platforms (simulation models), including processor models plus peripheral models necessary to boot an operating system (OS) or run bare metal applications. The platform and peripheral models included in the EPKs are open source so you can easily add new models to the platform as well as modify the existing peripheral models. The example OS and applications are also included.

OVP models work with both the OVPsim and the Imperas simulators, including the QuantumLeap parallel simulation accelerator. OVPsim is used for academic and other noncommercial users (over 1,000 university departments current subscribe to the OVP website), while the Imperas products are for commercial users. Imperas M*SDK includes the OVP model library, iGen for model development, support for heterogeneous, multiprocessor/multicore processors, a comprehensive Verification, Analysis, and Profiling (VAP) tool set, plus an advanced three-dimensional (temporal, spatial, and abstraction) debug solution, 3Debug, for heterogeneous multicore processor, peripheral, and embedded software debug. The VAP tool suite contains more than 50 tools supporting hardware-dependent software development, including OS and CPU-aware tracing (instruction, function, task, event), profiling, code coverage and memory analysis. The Imperas SlipStreamer patent-pending binary interception technology enables these analytical tools to operate without any modification or instrumentation of the software source code (i.e., the tools are completely nonintrusive).
