WebDec 5, 2011 · reactive agents can use the same sequencer/sequence infrastructure and can can be therefore controlled the same way as pro-active agents. eventually the only … 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 …
Webuvm_active_passive_enum is a UVM enum declaration that stores UVM_ACTIVE or UVM_PASSIVE. This is usually used to configure the agent to be either active/passive In … 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.

WebMar 10, 2024 · In UVM terms, you would require the following agents: One active agent to send transactions to the input of the encoder block. One passive agent to capture transactions at the output of the encoder block. One reactive agent to send transactions to the input of the decoder block.
WebThere 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. cleaning recipes using vinegarWebJul 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. doylestown pa roofersWebReactive Agents for UVM The Universal Verification Methodology is light on how to handle reactive drivers.

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 ... cleaning rear brakesWebApr 1, 2024 · A test has an environment, which has an agent, which has a monitor, driver, and sequence r.
