The USB 2.0 On-The-Go (OTG) IP Core is a 32-bit Avalon interface compliant core and supports ULPI interface. It supports both USB Host and USB Device peripheral functionality. While acting as USB Host, it supports High Speed (HS), Full Speed (FS) and Low Speed (LS) modes. While acting as USB Device peripheral, it supports High Speed (HS) and Full Speed (FS) modes.
IP core has been implemented in Verilog HDL and its functionality has been verified using different test cases in simulation environment as well as on hardware. It is provided as Altera Qsys Ready component and hence can be easily integrated in Qsys system.

Please Note: IP core contains parameter to select mode of operation. This allows resource optimization based on requirement. User can choose any of the following modes:
OTG (supports both host and peripheral functionality), DEVICE (supports peripheral functionality only) and HOST (supports host functionality only).
Verification:
- IP Core has been tested by interfacing it with USB 2.0 PHY (RN1133) on SLS HSIC development board.
