Features and Benefits: The MaxiSys® MS906CV is an advanced diagnostic device developed for customers looking for a tool with ultra-convenient and modern design while delivering ultimate performance. Each protocol has its own significance and applied according to the need of system application. The UVM environment instantiates one UVM agent (or VIP) for each protocol. Supporting UVM, this UART VIP is part of the asureVIP portfolio of implementation-proven VIP offerings. AVIP for I2C. They perform point to point communication which requires huge wiring connections, multiplexing of all. How to extend a protocol UVC (UVM Verification Component) to add custom extensions, maintaining proper encapsulation? A typical protocol (and its UVC) has concepts like states or modes (controlling operation in different circumstances) and phases or events (delimited regions or points of interest during the execution of a transfer according to the protocol).
