Requirements-based verification (RBV) is a popular verification process for FPGA designs used in safety-critical systems. The effectiveness of RBV is limited by the quality and precision of the requirements. Verification techniques such as constrained random verification with assertion-based verification (ABV) can be used to help identify ambiguous or incomplete requirements early in the design and verification process. The ability of assertions to increase the observability of the design can dramatically reduce debug time. Reducing the time spent debugging increases the time that can be spent searching for new bugs, leading to better verification quality.
In this webinar, Aldec presents how to optimize and verify requirements using SystemVerilog Assertions (SVA)
- Introduction to requirements-based verification
- Verification completeness
- Coverage usage and types
- Assertions-based verification
- Assertions planning and definitions
- Developing functional coverage with SVA
- Checking design requirements with SVA
- Using SVA for RBV
- SVA for developing design requirements
- SVA for specifying RTL code properties
- SVA to increase design observability
- Achieving completeness in requirements verification
Functional coverage is often mentioned together with constrained-random verification, which is a great combination.
How to make a simple, well-structured, and efficient testbench using the open-source Universal VHDL Verification Methodology (UVVM) architecture.
The FPGA design architecture is the single most important and primary factor in achieving development efficiency, quality, and reliability. The difference between a good and a bad design architecture can be about 50% of the workload.
In a team environment, verification engineers push code changes every day, and sometimes several times a day, to a shared repository. Each change has the potential to introduce new bugs into the design. Accordingly, when many changes are being made, it is difficult to...
Cocotb, an approach to using Python as a testing language, allows developers to start with small, directed test benches and evolve them into more thorough constraint random tests.
Open Verification Library (OVL) is a library of property checkers for digital circuit descriptions written in popular Hardware Description Languages and maintained by Accelera. The OVL checkers could be used not only in dynamic simulation, but also in formal...
Cycle related corner cases are probably the worst and main reason for undetected bugs on many FPGAs. To explain this in a simple way, – a cycle related corner case is for instance if you have an event counter where the number of counted events is critical and you read and reset this counter at regular intervals.
As with many popular useful standards, UVM has attained the coveted IEEE standardization in 2017. Interestingly, UVM is the first verification methodology to be standardized, and the current version is IEEE 1800.2-2020.
