Better FPGA Verification with VHDL: OSVVM – Leading Edge Verification for the VHDL Community
OSVVM is an advanced verification methodology that defines a VHDL verification framework, verification utility library, verification component library, and a scripting flow that simplifies your FPGA verification projects from start to finish. Using these libraries, you can create a simple, readable, and powerful testbench that is suitable for either simple or complex FPGA blocks. Looking… Read More »Better FPGA Verification with VHDL: OSVVM – Leading Edge Verification for the VHDL Community
Better FPGA Verification with VHDL – Faster than “Lite” Verification Component Development with OSVVM
Some methodologies (or frameworks) are so complex that you need a script to create the initial starting point for writing verification components, test cases, and/or the test harness. SystemVerilog + UVM is certainly like this. There are even several organizations that propose that you use their "Lite" or "Easy" approach. Creating a verification component (VC)… Read More »Better FPGA Verification with VHDL – Faster than “Lite” Verification Component Development with OSVVM
OSVVM’s Test Reports and Simulator Independent Scripting
According to the 2020 Wilson Verification Survey FPGA verification engineers spend 46% of their time debugging. As a result, we need good scripting to simplify running tests and good reports to simplify debug and help find problems quickly. Scripting can be complicated no matter what language – particularly with EDA tools that need to stay… Read More »OSVVM’s Test Reports and Simulator Independent Scripting
Advances in OSVVM’s Verification Data Structures
OSVVM has grown tremendously over the last couple of years. This period saw simulator independent scripting, test reporting, model independent transactions, virtual transaction interfaces, and additional verification components, each added and incrementally improved. We have talked about these previously in this webinar series. This webinar focuses on advances in OSVVM data structures. OSVVM's Functional Coverage,… Read More »Advances in OSVVM’s Verification Data Structures
