LIVE WEBINAR: UVM-based Verification of Custom Instructions with RISC-V Cores


UVM-based Verification of Custom Instructions with RISC-V Cores

Presenter: Roddy Urquhart, Senior Marketing Director, Codasip
Thursday, September 17, 2020


By integrating Aldec’s Riviera-PRO™ with Codasip’s Studio™, verification of RISC-V CPU custom instructions at the RTL implementation level becomes an incredibly powerful platform for RISC-V processor deployment.

In this presentation, we will show in Studio, how users can describe the RISC-V architecture and add custom instructions using CodAL high level language, modify the pipeline, configure random instruction generator, auto-generate the HDK, SDK, RTL implementation and C++ reference model and UVM environment, start RTL simulation, setup breakpoints and debug.

We will then show in Riviera-PRO, how users can run RTL simulation and debug applications and core architecture, inspect simulation waveforms, use the UVM Graph & Toolbox to view the graphical representation of the UVM components, objects and the transaction level modeling (TLM) connections between them, giving the user an overall perspective of the testbench architecture and the dataflow. We will also show how you can collect and analyze both functional coverage and code coverage.

Zdenek Prikryl

Zdenek Prikryl, Chief Architect, Codasip


Dr. Prikryl has undertaken research at Brno University of Technology which led to the creation of processor development tools at Codasip. Specifically, he was a developer of the methodology to automatically generate hardware and software development kits from a processor description language. Dr Prikryl has been chief architect of Codasip Studio for over ten years and has been the architect of diverse processor cores including but not limited to 16/32-bit architectures for IoT, 32/64bit DSP oriented architectures or Linux capable architectures. All of these architectures were developed using Studio and many of them were based on RISC-V ISA.
