WebThe UVM has ACTIVE and INACTIVE agents where an INACTIVE agent is simply one that never drives a bus. What you want is sometimes called a slave sequence, or a responder. … WebReactive agents are software agents that carry out a simple task of retrieving pre-set behaviors similar to reflexes. Reactive agents do not maintain the internal state, unlike deliberative agents. Finding a difference between reactive agents and deliberative agents can be indistinct though. chintur pin code

WebInterrupt handling in UVM Test Bench. In this blog post, we will go over the implementation of interrupt handling in the UVM Test bench (TB) environment. In a DUT, typically there will be one or more interrupt pins. Related to interrupts, TB. Would need to check the correctness of interrupts. May need to have routines to service the interrupts. Webuvm_active_passive_enum is a UVM enum declaration that stores UVM_ACTIVE or UVM_PASSIVE.

IEEE UVM from 2024 and onwards … WebMar 31, 2011 · I see several possible solutions: 1.) Create a sequence (like the interrupt sequence) that would be created inside the sequencer and would get triggered by an event. 2.) Modify the Agent's driver so that it could be configured as either a Master or Slave.
