Update #6

New OVP MIPS/NEC models available.
Changes in Virtual Platform Suppliers

New MIPS and NEC models
We have made press announcements today regarding the release and use of the new OVP MIPS and NEC processor models. These are now available as binaries ready to use or as open source under Apache 2.0 licensing. The models run at the normal OVP speeds of 100's of MIPS.

The new models are the MIPS32 74K and 1004K families with the 1004K being multi-core. All are tested and validated by MIPS Technologies(tm) under the MIPS-Verified(tm) program. The NEC family are the NEC Electronics v850 32 bit RISC processors.

All the models can be used with C and the normal OVP APIs and they also come with SystemC TLM2.0 interfaces and can be used with any OSCI compliant SystemC simulator.

The press release also includes quotations from OVP users who have gained significant performance benefits by using the OVP NEC models.

For the full text of the press release, please read the full press release (http://www.ovpworld.org/newsblog).

Changes in Virtual Platform Suppliers
This past week has seen changes in the ownership of three of the smaller Virtual Platform suppliers. The technology developed by VaST for cycle approximate modeling has been purchased by Synopsys though it is not clear that the staff have been retained. Several years ago we came to the conclusion that the hand coding of cycle approximate models was a tough business and that the future would be cycle accurate models derived from RTL (like Carbon) and very fast Instruction Accurate modeling like Virtutech, Imperas/OVP, and ARM's Fast Models. This end of the road for VaST seems to confirm our prediction.

Late last week Intel announced that it was acquiring Virtutech and Intel (the Wind River wholly owned subsidiary) will distribute the old Virtutech tools. This is very interesting as it confirms Intel being serious in the embedded market for Atom and confirms our view that Instruction Accurate models are very important for embedded software development. However it should concern non-Atom users as Virtutech just lost its ability to be independent.

And if that wasn't enough, this week CoWare announced they had been acquired by Synopsys. This means that Synopsys now has a lot of (expensive) engineering staff who can provide services to their customers who need models building using a variety of proprietary modeling technologies (acquired from Virtio, VaST, and now CoWare). What is interesting is that the open source OVP processor modeling technology is still unique and works well with the SystemC TLM2.0 glue Synopsys use to stick platforms together. The use of ultra high speed OVP processor models in the platforms Synopsys develop for their customers is perfect usage of the Open Virtual Platforms technology and will provide a great solution for Synopsys customers. We look forward to working closely with them on that. We are charter founding members of the Synopsys System-Level Catalyst Program.

OVP news
More and more users are downloading and using the free open source OVP processor models. Some are using them with the OVP ICM C API and some using SystemC and even some using them with Verilog HDL simulators. Since inception OVP now has well over 2,000 registered users and there are more than 20 universities using OVP for research or teaching. There are 40+ processor models available from OVP with MIPS and ARC models verified by the IP owners.

The events of recent weeks confirm the approach that we have been taking with OVP and helps to make OVP the defacto place to come for fast models.
