This is pretty typical. Without details, the general outline is: Create and configure the agents just as you have described. The masters and slaves will be configured as active. A slave agent is typically a reactive agent that responds to stimulus from the DUT so in that case, sequence items in the slave driver will be initiated by ... 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.

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.

WebJul 5, 2024 · The UVM register layer acts similarly by modeling and abstracting registers of a design. It attempts to mirror the design registers by creating a model in the verification testbench. By applying stimulus to the register model, the actual design registers will exhibit the changes applied by the stimulus. balade satignyWebApr 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. balades angersWebThere are four basic reporting functions that can be used with different verbosity levels. where * can be either info, error, warning, fatal. UVM has six levels of verbosity with each one represented by an integer. Note that the VERBOSITY_LEVEL is only required for uvm_report_info. Usage of uvm_report_fatal will exit the simulation. argentian arabia
