In Common Verification Methodology (UVM), reaching excessive efficiency typically necessitates sending transactions to the Design Beneath Take a look at (DUT) in a non-sequential method. This method, the place the order of transaction execution differs from their era order, leverages the DUT’s inner pipelining capabilities to maximise throughput and stress timing corners. Think about a sequence of learn and write operations to a reminiscence mannequin. A standard, in-order method would ship these transactions sequentially. Nevertheless, a extra environment friendly method would possibly interleave these operations, permitting the DUT to course of a number of transactions concurrently, mimicking real-world eventualities and exposing potential design flaws associated to concurrency and information hazards.
Optimizing driver effectivity on this approach considerably reduces verification time, notably for complicated designs with deep pipelines. By decoupling transaction era from execution order, verification engineers can extra successfully goal particular design options and nook circumstances. Traditionally, reaching this degree of management required intricate, low-level coding. UVM’s structured method and inherent flexibility simplifies this course of, permitting for classy verification methods with out sacrificing code readability or maintainability. This contributes to increased high quality verification and sooner time-to-market for more and more complicated designs.
