UVE - Unified Verification Environment

Unified Verification Environment

The increasing complexity of digital systems disrupts the development process in the sense that the verification of these designs is becoming longer. To reduce the verification time, manufacturers of industrial EDA tools offer more sophisticated ways, particularly through the use of verification languages like SystemVerilog. Some verification IPs (Intellectual Property) are also beginning to appear, to accelerate the verification process.

However, learning these new tools and new methodologies requires a significant investment from the industry. Their complex implementation and cost are often an obstacle to their introduction. It therefore becomes necessary to offer manufacturers the means to support them in this transition and increase the return on investment of implementing such tools and methodologies.

In this context, the aim of the UVE project is to create a software tool able of automatically generate a verification testbench written in SystemVerilog and integrating the UVM methodology. It allows to rapidly have a verification environment able of performing simulation on a DUV (design under verification). UVE includes a graphical user interface, a code generator, compilation scripts and a library of verification IPs (VIP). One of the main innovations resides in the fact that this tool proposes to the user a todo list for testbench finalization.

Moreover, the graphical interface lets the user observe the testbench structure that is generated. Files can be accessed easily by double clicking on the graphical view. Simulation can be launched directly from the tool.

UVE is now an operational open-source framework that can be downloaded from http://www.systemverilog.ch/. Some improvements could take the form of adding new VIPs in the library.
