7/31/2002 - Modelware, a leading provider of semiconductor intellectual property for the telecommunications and networking industry, today announced the availability of version 3.0 of its POS-PHY Level 4 (PL4)/SPI-4 Phase 2 (SPI-4.2) cores. This version of Modelware’s PluriBus™ PL4/SPI-4.2 Foundation and Manager cores includes advanced features such as hitless bandwidth provisioning, high-speed FIFO Status channel, and a 128-bit user interface option to ease the integration task for ASIC and FPGA customers.
Modelware’s PluriBus™ PL4/SPI-4.2 cores fully comply with the Optical Internetworking Forum’s (OIF) SPI-4.2 standard. Interoperability with PMC-Sierra’s XENON family of OC-192c POS/ATM, 10 Gigabit Ethernet devices was also verified in simulation with PMC-Sierra’s PL4 models.
“Interoperability with Modelware’s off-the-shelf, re-usable IP cores is important for reducing our customer’s product development cycles,” says Steve Perna, vice president and general manager of PMC-Sierra’s Optical Networking Division. “PMC-Sierra and Modelware’s success in achieving PL4/SPI-4.2 interoperability further demonstrates our commitment in providing world class support to our customers.”
About Modelware’s PL4/SPI-4.2 Foundation and Manager Cores
Modelware’s PluriBus™ PL4/SPI-4.2 Foundation core fully implements the PL4/SPI-4.2 protocol and provides an easy-to-use interface to the user’s logic. In addition to the functions provided by the Foundation core, the Manager core implements per-channel buffering, flow control, and credit- based data transfer scheduling. Both cores are delivered in a ready-to-use package including a comprehensive test environment, synthesis scripts, and device layout guidelines. Modelware’s PL4/SPI-4.2 ASIC license pricing starts at $75,000.
Modelware has been licensing PL4/SPI-4.2 cores since November 2000 and has continued to enhance the performance and features of these products. Among Modelware’s first licensees were Azanda Network Devices and Xelerated Packet Devices.
“Modelware’s support was outstanding when we were integrating the SPI-4.2 core,” says Kaushik Patel, vice president of Engineering at Azanda Network Devices. “When our first silicon devices arrived, the Modelware SPI-4.2 core was fully functional and allowed Azanda’s full duplex OC-48 Traffic Manager and ATM SAR ScimitarTM device (AZ61100) to interoperate flawlessly with PMC-Sierra’s PM5390 S/UNI-9953 device.”
Joachim Roos, vice president of Engineering of Xelerated said, “Incorporating third-party IP in the high-speed SPI-4.2 10 Gbps interfaces of our Network Processor has been a delicate balance of saving in-house design resources and meeting high quality demands. We are very happy to have found that combination with the Modelware SPI-4.2 interface, which is successfully incorporated in our X10 Network Processor line of products.”
PMC-Sierra’s 10-Gigabit Ethernet XENON Family of Devices
PMC-Sierra’s XENON family of devices is one of the industry’s broadest set of 10 Gigabit Physical Layer and Framer/10 Gigabit MAC solutions. The XENON family includes the PM5390 S/UNIŇ-9953 (10 GE LAN/WAN PHY with 10GE MAC, PCS, WIS and OC-192 ATM/POS concatenated PL4 framer), PM5392 S/UNI-9953-POS (OC-192 POS/ATM concatenated PL4 framer), PM3392 S/UNI-1x10 GE (10GE LAN PHY, MAC and PCS with PL4), and PM3388 S/UNI-10xGE (10 port GE PHY, MAC, PCS and integrated SERDES with PL4) devices.

About PL4/SPI-4.2 Standard
POS-PHY Level 4 (PL4) originated from the SATURNŇ Development Group, co-founded by PMC-Sierra in 1992. It has since been standardized in the OIF as System Packet Interface Level 4 Phase 2 (SPI-4.2) and in the ATM Forum as Frame-Based ATM Interface Level 4 (FBATM-4). PL4/SPI-4.2 is an industry standard multi service system interface supporting OC-192, 10 Gigabit Ethernet and multichannel configurations, including 2.5 Gbit/s OC-48, 622 Mbit/s OC-12 and Gigabit Ethernet, as required by the new generation of super routers and Layer 3 switches used in multiservice voice and data networks. The interface is flexible, supporting high-speed Packet-over-SONET (POS) Internet traffic as well as 10 Gigabit Ethernet, Gigabit Ethernet and Asynchronous Transfer Mode (ATM) applications.
