OVP is the Open Virtual Platform. It is provided by the company Imperas. OVPSim is a virtual platform and modeling technology that enables simulating embedded systems running real application code. The Simulations run at speeds of 100s and 100s of MIPS on typical desktop PCs and are completely Instruction Accurate and model the whole system.

It has a platform model building wizard called iGen that facilitate easy platform building. It is fairly easy to put together a simulation model of a platform, compile the model to an executable, and connect it to your debugger to provide a fast embedded software development environment.

The OVPsim™ simulator, including full documentation and examples, demos and available processor models, among others ARM, Imagination MIPS, Synopsys ARC, Renesas v850 / RH850 / RL78 / M16C, openCores OR1K, PowerPC, Altera Nios II, Xilinx MicroBlaze, RISC-V, single core, multicore, manycore, C, C++, SystemC, TLM2 etc, are avaialbe on the web site. Imperas and others have put many of the processor and peripheral models into open source and made them available on this site on the download and library pages.
