In Common Verification Methodology (UVM), attaining excessive efficiency typically necessitates sending transactions to the Design Underneath Take a look at (DUT) in a non-sequential method. This method, the place the order of transaction execution differs from their technology order, leverages the DUT’s inside pipelining capabilities to maximise throughput and stress timing corners. Take into account 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 may interleave these operations, permitting the DUT to course of a number of transactions concurrently, mimicking real-world situations and exposing potential design flaws associated to concurrency and knowledge hazards.
Optimizing driver effectivity on this method considerably reduces verification time, notably for advanced designs with deep pipelines. By decoupling transaction technology from execution order, verification engineers can extra successfully goal particular design options and nook instances. Traditionally, attaining this stage 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 greater high quality verification and quicker time-to-market for more and more advanced designs.
