WebMASTERING REACTIVE SLAVES IN UVM. Mark Litterick Jeff Montesano Taruna Reddy. Verilab Munich (Germany) & Austin (USA). www.verilab.com. ABSTRACT. In most interface protocols a component can either be a master, which initiates the transactions or a slave, which responds to these transactions. Generating constrained-random request … WebApr 7, 2024 · But even worse, clocking block events are intended to be triggered by events in the active region. If you try generating a clock in the reactive region by creating a UVM clock driving agent, that can lead to races with input sampling. (See section 14.13 Input sampling in the IEEE 1800-2024 SystemVerilog LRM.

Webwww.verilab.com WebThe simplest option is to execute the transaction directly on a sequencer using uvm_sequencer_base::execute_item (uvm_sequence_item). But you can't get the response back as the execute method uses a temporary sequence. So at the end you may simply need to inline the execute code into your test.

"WebApr 19, 2024 · If you receive the response in a different agent then there is no simple answer. It needs some more investigations. If the respinse is an interrupt you might add the interrupt signal/signals to the initializing interface. If there is no direct relationship you have to use horizontal synchronization. There are different approaches. " - Reactive agent in uvm
