PartMiner, which filed for an IPO before Wall Street slumped, had intended to issue 5 million shares on the Nasdaq stock exchange and sell them at $8 to $10 each.

Mentor Graphics has registered strong objections to sections 9 and 11, and is refusing to join OSCI until they change. What [section 9] means is that if Mentor Graphics sues Synopsys for any reason, our license will be revoked,” said Serge Leef, general manager of Mentor's system-on-chip verification division. This is a serious issue. No company wants to give up its legal rights.”

Dennis Brophy, chairman of Accellera and director of strategic business development at Model Technology, took aim at section 11. If Synopsys is making an independent body, this SystemC initiative should have the rights to publish the license, control it and shape its destiny,” he said.

One member of the OSCI board — Vassilios Gerousis, design system architect at Infineon Technologies — also has questions about the organization's independence. Although it's a separate organization, the people who are running it are Synopsys and CoWare,” Gerousis said. They're the people who set the agenda together, even for committee meetings.”

Gerousis believes Synopsys and CoWare should restrict themselves to developing a language reference manual, as opposed to licensing software. That way people don't have to worry about software, don't have to worry about patents, and anybody can participate,” he said. That was my agreement with them initially, but this did not materialize.”

Gerousis, who also oversees Accellera's technical committees, said there is currently no coordination between OSCI and Accellera's System Level Design Standards group. I believe for them [OSCI] to survive in the industry, they need to cooperate with other groups,” he said.

But OSCI co-chairs Kranen and Pete Hardee, director of product marketing at CoWare, defended sections 9 and 11 as common components of open-source licensing agreements.

The intent of section 9, Kranen said, is not to prohibit licensees from suing contributors for any reason. The whole intention is for people to contribute freely to SystemC. It's kind of a safety valve for contributors,” he said. If CoWare has donated patents to SystemC, Kranen said, those patents shouldn't be used against CoWare in a legal dispute.

But Kranen acknowledged that the wording speaks of software patents in general, not SystemC-related patents. Asked about Skilken's hypothetical Mentor-vs.-Cadence emulation lawsuit, Kranen replied, that's one the lawyers would have to make a call on.” Kranen didn't give much hope to those who think the independent OSCI will phase out this provision. We'll have to examine things as they go forward and see if anything is impeding the growth of SystemC,” he said. Right now, this is not.”

Reaching end users

Simutech last year announced its eValab product, which uses FPGA-based CoreBoards to represent individual IP blocks. That product, said Steve Glaser, Simutech's vice president of marketing, is mostly deployed at internal reuse centers of large semiconductor companies. To reach end users, Simutech is now offering to host eValab IP Services for the semiconductor vendors.

Following successful completion of a pilot project last year, the hosting will take place at the Scottish Alba Center. But the actual location of the machines won't concern the end user, who will access eValab services through a Web portal provided by the IP supplier.

The service will let an IP user do a catalog search, and then actually run a remote evaluation of the IP, assuming there's a CoreBoard for it. Users can select algorithms or data sets, or they can upload their own software to run it on the IP block. For a single IP component, said Glaser, speeds can be very fast — up to 150 MHz for a DSP, for example. But with multiple IP components, speeds decline to 2 to 5 MHz, because of the need to use the eValab's backplane.

Simutech is now offering setup, hosting, and profiling services to the IP vendors, who will pay for the service. Customers include Infineon, Toshiba, and Amphion (the former Integrated Silicon Systems). Glaser said that private session” services are being made available now, and that public access to eValab IP Services is expected late in the second quarter.
