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 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 ... »
I just posted 2022.05a release. 2022.05 added html transcripts capability to a larger set of tools. Unfortunately this capability requires a new version of TCL that is not supported by older tools, such as Riviera-PRO 2018.02. 2022.05a release fixes this. If you have issues, you can report them in the OSVVM forum, on github issues, or you can send them directly to me. The first two being most reli... »
For some time now, OSVVM has been doing releases every month. Sometimes I talk about them, sometimes they just get posted to the downloads page. Over the past several releases OSVVM has: Improved documentation. Improved our already best in industry test reporting capability. Improved scripting capabilities. Find code coverage tedious – we run, save, merge, and report it in a very simple... »
Improve your verification capabilities with Open Source VHDL Verification Methodology (OSVVM). OSVVM simplifies your FPGA and ASIC verification tasks by providing utility and model libraries. Using these free, open source libraries you can create a simple, powerful, concise, and readable testbench that is suitable for either a simple FPGA block or a complex ASIC. About 2022.02 Release 2022.02 cont... »
In reply to a LinkedIn post that regurgitated the old statement that VHDL is verbose, I replied, “With the VHDL-2008 update, Verilog is more verbose than VHDL.” This led my old friend Cliff Cummings and I to trade a few VHDL vs. System Verilog jabs. One of the things he brought up as concise SystemVerilog verification capabilities are singletons and verification data structures. Rather than give a... »
In this second webinar of the VHDL-2019: Just the New Stuff series we will focus on enhancements to VHDL’s protected type capabilities. Protected types simplify and abstract the construction of data structures. As such they are the enabling feature that makes it possible to create VHDL verification methodologies that are competitive with SystemVerilog + UVM, such as Open Source VHDL Verifi... »
IEEE 1076-2019, fondly referred to as VHDL-2019, was approved by IEEE RevCom in September 2019 and published in December 2019. The effort was supported mainly by VHDL users – from requirements definition to LRM writing. This is different from the past where employees of EDA vendors did much of the work – particularly the LRM writing. Language changes were use model driven and had multiple opportun... »
