WebSep 12, 2024 · With this model, a PSS processing tool can analyze the resulting graph and create a virtual sequence in UVM that will achieve 100% coverage. This is the major difference between a procedural stimulus description, like UVM sequences, and a declarative stimulus description, like PSS. Image A PSS tool can generate multiple … 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. 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.
