OSVVM release 2023.07 updates OSVVM’s Requirement Tracking (aka Specification Tracking) capability so that HTML and CSV based merged requirements reports are produced automatically. Requirements Tracking (Part 1) started with the 2020.08 release. In the 2020.08 release, each test could write out a CSV requirements report. The expectation was that external requirements tools imported these and merg... »
Summary of 2023.07 Changes AlertLogPkg: Added WriteRequirementsYaml to write requirements for a test case into a YAML file ReportPkg: In EndOfTestReports if GotRequirements it calls WriteRequirementsYaml. Hence saving requirements is automatic. Scripts: For each test suite, merges the requirements yaml files for each test case and produces a test suite requirements HTML Scripts: For each bu... »
Summary of 2022.12 Changes Updated StartUp.tcl to use OSVVM_TOOL environment variable to determine which tool is run when none is found Updated scripts for Synopsys VCS and Cadence Xcelium Updated log file creation to first use OsvvmBuild.log and then it is copied to “LogFileDirectory”/”BuildName”.log. Updated Generic Handling Both Simulate and RunTest support callin... »
As I was writing the blog about the 2022.10 Multiple Verification Component example, my focus was drawn to the issue, “How do I call transactions that iterate across an array of verification components?” Solving this issue became the main goal of the 2022.11 release. The 2022.11 release includes: Updated Multiple Verification Component Test Example Created AddressBus and Stream transac... »
Summary of recent changes in OSVVM. Added Ethernet Phy and MAC verification components for GMII, RGMII, MII, RMII Added interrupt handler that supports any verification component that uses the Address Bus Model Independent Interface RandomPkg: added SetRandomSalt as a method to add an offset to all InitSeed calculations – Thanks Torsten M Added demo of using multiple OSVVM VC using “fo... »
Summary of recent changes in OSVVM: Scripts updated for better signaling to continuous integration (CI) tools MemoryPkg updated to remove 31 bit limitation and support storage policies. Reports keep getting better Scripts now support simulating with two top level designs Scripts updated to better support GHDL options and waveforms Scripts now support callbacks to simplify user customization Script... »
Summary of Changes in 2022.06 Scripting: At build completion, print single-line, text-based build summary Scripting: Improved Error Handling. (continuing from 2022.05) Scripting: Updated HTML log file generation. Log file always created. HTML optionally created Scripting: Optional generation of a do file – for submitting bug reports to vendors Scripting: Added Generic handling for simulate: ... »
Abstract 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. OS... »
Abstract 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 rooted in one directory while it is advantageous ... »
