Verification IP for USB

• Complete solution for USB 2.0, OTG, Superspeed 4.0, Power Delivery (PD 3.0), and xHCI
• Runs over USB Type-C® interconnects
• Tunnels USB3, PCIe, and DP protocols
• Supports UAS/BOT core through SoC verification
• Host, device, and hub models
• PIPE/PHY models for USB3/USB2/PD with Type-C interface or SSIC/M-PHY
• Supports xHCI host controller IP development using xHCD host driver agent
• Compliance test suite for protocol, link, and physical layer verification of host, device, hub, and PHY
• Comprehensive assertions track USB compliance coverage
• Functional coverage tracks range of packet traffic, FSMs, and complex operational sequences
• Packet and symbol tracker monitor output to improve debug

Major features

• Host performs bus enumeration and allo cates USB pipes for communication between host and each endpoint
• Program TP sequences for bulk, isochronous, interrupt, bulk stream, and control transfer types
• Program USB device requests to access USB device descriptors
• Automatic frame scheduling and bus inter val and service interval support, including ITP generation
• Program host and device model timing parameters and response behaviors, such as link commands
• Fine-grained control over LTSSM transition sequences
• Fine-grained link layer controls
• Inject errors at all layers through callbacks
• Control device operation state transitions, including suspend/resume
• Full power management support (U0-U3), including automatic and software directed entry/exit
• Power on and inband reset
• xHC driver emulates hardware/software interface between system software and the host controller hardware
• xHC driver model implements all host side memory data structures and register-level host controller interfaces for USB 2.0/4.0, including complex randomized ring memory allocation
• xHC compliance test suite is also supported.
• The xHC driver VIP interfaces with xHC host controllers via PCIe and AMBA
• Mass storage class host implements the USB attached SCSI protocol (UASP) and bulk-only transport (BOT) protocols and supports the SCSI and task management commands found under SPC, SBC, RBC, and SAM
• Mass storage class test suite performs SCSI command compliance, performance, and power state verification, and provides cover age monitoring of the USB throughput and SCSI command completion status

• Verifies USB-based designs
• Allows customized tests at several levels of abstraction
• Enables full control over the DUT to initiate transactions via HCDI operations
• Supports device and PHY-only core verification
• Supports random and directed test cases
