Mentor Graphics USB On-the-Go Intellectual Property Achieves Compliance Certification

WILSONVILLE, Ore., August 27, 2003 - Mentor Graphics Corporation today announced that two of its Universal Serial Bus (USB) On-The-Go (OTG) intellectual property (IP) cores achieved compliance certification at the USB Implementers Forum (USB-IF) Compliance Workshop held in Milpitas, Calif. July 29 to Aug. 1. This was the first opportunity to test the Mentor Graphics® Full Speed (MUSBFDRC) and Hi-Speed (MUSBHDRC) Dual Role Controllers against the OTG standard. Certification validates the quality of Mentor Graphics IP and allows developers to integrate the company's cores with the utmost confidence, enabling the rapid creation of OTG applications.

USB-IF Compliance Workshops are held regularly to promote USB product development, validate product compliance with the specification, help foster communication between product manufacturers and ensure that USB Peripherals operate together. The three-day event evaluates products against the standard for Full Speed OTG with exacting tests for device interoperability, as well as ensuring strict electrical and protocol compliance.

Mentor Graphics tested its MUSBFDRC core on an ARM Integrator platform with an AMBA bus interface and on an 8051-based reference platform with a VCI interface. For interoperability testing, the platforms ran the new Mentor Graphics embedded OTG stack, providing application-level support in both host and peripheral modes of operation. In addition to this, the MUSBHDRC core was tested for Full Speed OTG device compliance. In all tests, the cores achieved full certification.

"Mentor Graphics is committed to ensuring that all its cores are certified compliant by the respective standards bodies," said Michael Kaskowitz, general manager of the Mentor Graphics Intellectual Property Division. "At the first opportunity for certification, our cores and software passed all the required compliance tests, validating the quality of the IP and embedded software that we deliver."

The Mentor Graphics Inventra USB Dual-Role Controllers (MUSBHDRC and MUSBFDRC)
The Inventra^TM cores are fully synthesizable dual-role controller macrocells that support both host and peripheral functions in a single package. The major product features are:

• Operates as a standard peripheral controller when connected to a host
•  Operates as a host controller when connected to a peripheral device
• Operates as either host or peripheral when connected another OTG device, fully supporting both Host Negotiation Protocol (HNP) and Session Request Protocol (SRP)
• Configurable for up to 16 transmit and 16 receive endpoints
• Optional VCI-compatible CPU interface
• Optional AMBA-AHB CPU interface with DMA controller
• Graphical User Interface provided for core configuration

The Inventra MUSBFDRC and MUSBHDRC cores are designed to respect the power requirements of portable devices. All Inventra cores are delivered to the highest standards and are available in Verilog and VHDL, with full testbench and documentation.  Accompanying the cores is a designed-for-purpose OTG software stack, with a range of available peripheral and host device drivers, ported to various embedded operating systems.
