uvm adapter

UVM (Universal Verification Methodology) adapter is a component of the UVM framework that provides a way to connect two interfaces with different signal timings or protocols. It acts as a bridge between two interfaces, allowing communication between different parts of the system.

The UVM adapter converts the signals from one interface to another, so that the signals can be understood by the receiving interface. It usually contains two parts: the driver and the monitor.

The driver is responsible for translating the signals from the source interface to the target interface, while the monitor is responsible for translating the signals from the target interface back to the source interface.

UVM adapters are commonly used in verification environments where different blocks or modules are designed using different protocols, such as communication between a processor and a memory, or between a PCIe interface and a custom interface.
