Randomization – The Why, When, What & How

FPGA Design/Verification Best Practices for Quality and Efficiency

12. May 3:00 PM – 4:00 PM

Randomization is very important for modern verification. Still, very few designers apply randomization sufficiently in their testbenches. This means they are missing out on a very important method for finding potential bugs in their design, and as a result, their products have significantly more undetected bugs. Randomization can be used in many ways, but it is of course, also important to know when not to use it.

This presentation will show several levels of applying randomization, both with respect to the actual DUT and the randomization functionality available. The main principles shown are tool independent, but the new UVVM randomization functionality will be used as examples, thus also giving you a kick start using this great tool.

FPGA Design Architecture Optimization

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.

The most error prone FPGA corner cases

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.
