The paper was published at DVCon 2011 and you can get a free copy of it: "Easier UVM for Functional Verification by Mainstream Users". Analysis port (class uvm_tlm_analysis_port) — a specific type of transaction-level port that can be connected to zero, one, or many analysis exports and through which a component may call the method write implemented in another component, specifically a subscriber. UVM中内建了uvm_subscriber类，可以被当作观察者或者订阅者使用。 一般用在构建功能覆盖率的收集。伪代码如下： 订阅者订阅monitor中收集到的transaction，覆盖率模块，参考模型，scoreboard都是订阅者。A Scoreboard is a checker element that keeps a tally on the input stimulus, and the expected output. The uvm_component class is a base class for all UVM components. UVM uses the concept of a factory where all objects are registered with it so that it can return an object of the requested type when required. The paper shows simplified, non‐UVM, analysis port implementations to clarify how 1 Answer. You should implement the pure virtual function void write (T t); which inherits from uvm_subscriber class in your checker_subscriber class.

A request type is not required here because this sequencer is generic and not limited to handle only one particular data type. This brings about. Recived trans On Analysis Imp Port UVM_INFO component_b. The imp port then forwards the calls to the component that instantiates it. In the build_phase (), sequencer and driver are created only if the agent is configured to be active. 16 We use the uvmenv class to hold the structure of the testbench then we use from DCAE 001 at Politehnica University BucharestOnce the connection is made, the driver can utilize API calls in the TLM port definitions to receive sequence items from the sequencer. As usual the code compiles w/o error, and functions if I remove the port code. Rather than. An imp is the endpoint; (with the subscriber pattern) it is this that calls the write method. The uvm_subscriber base component can be used to simplify this operation, so a typical analysis component would extend uvm_subscriber as: class sub1 #(type T = simple_trans) extends uvm_subscriber #(T);.
