The Top Most Common SystemVerilog Constrained Random Gotchas
نویسنده
چکیده
The Constrained Random (CR) portion in any verification environment is a significant contributor to both the coding effort and the simulation overhead. Often, verification engineers waste a significant amount of time debugging problems related to CR in their SystemVerilog[1], and UVM[4], testbenches. The paper illustrates the top most common SystemVerilog CR gotchas, which when carefully studied and addressed would help decrease debug times related to CR, reduce random instabilities, and boost productivity. Keywords—SystemVerilog; UVM; Constrained Random; Random distribution; Random Stability

Hardware accelerated constrained random test generation
Recent design and verification languages, such as SystemVerilog, support a rich test bench language, which provides significant support towards developing layered, structured, constrained random test bench architectures. Typically, the test bench language offers many features that are not synthesisable and therefore cannot be carried into the hardware for hardware accelerated simulation. One of...
متن کاملSplittable stochastic project scheduling with constrained renewable resource
This paper discusses the problem of allocation of constrained renewable resource to splittable activities of a single project. If the activities of stochastic projects can be split, these projects may be completed in shorter time when the available resource is constrained. It is assumed that the resource amount required to accom-plish each activity is a discrete quantity and deterministic. The ...
متن کاملEnriching UVM in SystemC with AMS extensions for randomization and functional coverage*
The Universal Verification Methodology (UVM) is a coverage driven verification approach, which has become the standard for the verification of digital systems. The framework provided by UVM makes it possible to create structured test environments, which facilitates the reuse of verification components and scenarios. However, the UVM library is only available for SystemVerilog, limiting the veri...
