There are many things that differentiate VHDL from Verilog. One example, is the ability to use global signals in Verilog, which enables a signal at the top-level to connect to one or more points in the hierarchy. This particular feature is used very effectively by Xilinx, to distribute the Global Set/Reset signal GSR to their IP and cell simulation models. The signal is generated in the glbl.v, wh... »
We are very pleased to post a real example OSVVM experience which has been shared by Miroslav Marinkovic. Miroslav has made use of Functional coverage, Random test generation and Intelligent Coverage Randomization and Message logging and reporting : Alerts and Affirmations in his testbench. We want to test BCH code which provides DEC-TED capability (Double-Error-Correction, Triple-Error-Detection)... »

Through SynthWorks, Mr Lewis has been offering VHDL training for 25+ years and on-line training for 10+ years. So don’t worry, we got this. Your on-line class session will be great. Our on-line class sessions are offered in a relax... »
I will be in Europe in March doing presentations on Open Source VHDL Verification Methodology (OSVVM) at the 2nd Workshop on Open-Source Design Automation (OSDA) and at the 5th Space FPGA Users Workshop (SEFUW). OSDA, Friday March 13 First stop is Grenoble, France. I will be presenting an hour long talk on OSVVM on Friday March 13 at OSDA which is held in conjunction with Design, Automation, an... »
Over the last year, OSVVM has been growing rapidly. I was delighted to have the opportunity to present OSVVM papers at FPGA World (both Stockholm and Copenhagen) and at DVCon Europe in Munich. In addition, between September and November 2019, I delivered six (!) OSVVM focused Advanced VHDL Testbench and Verification training courses through my company SynthWorks and through our European partners F... »
Open Source VHDL Verification Methodology (OSVVM) has been named the number #1 VHDL Verification Library by The 2018 Wilson Research Group ASIC and FPGA Functional Verification Study. While your EDA vendor may have told you that only enthusiasts use VHDL for verification, the survey results report that OSVVM is used as the FPGA Verification Library for 17% of world wide market. According to the s... »
In the latest release of Open Source VHDL Verification Methodology (OSVVM), all licenses for the entire OSVVM library (utility and model libraries) were updated to Apache 2.0 license. This is being done in preparation to migrate OSVVM to IEEE Open Source. VHDL’s adventure started with IEEE Open Source started with a pilot program for releasing the IEEE std 1076-2019 (VHDL LRM) pac... »
Open Source VHDL Verification Methodology (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. This webinar is a guided walk-through of the OSVVM verification framework and transac... »
Webinar Taming Testbench Messaging and Error Reporting with OSVVM’s Logs and Alerts. Thursday April 5, 2018 Printing and error reporting in VHDL are tedious, yet necessary testbench tasks. Fortunately, Open Source VHDL Verification Methodology (OSVVM) provides library utilities to simplify these tasks. This presentation covers the details of OSVVMs transcript utility in TranscrptPkg as well ... »
