Can you implement randc logic using ONLY rand? This advanced SystemV erilog interview question tests if you really understand constraints.
In this video, we go beyond the built-in keywords to build a custom cyclic randomization mechanism. This is a favorite "gotcha" question at top-tier product companies like Qualcomm, Intel, and NVIDIA.
✅ What you’ll master:
The internal "Permutation Set" logic of randc.
Step-by-step implementation using rand + tracking arrays.
How to handle the "cycle reset" without simulator errors.
Clean, interview-ready code you can explain with confidence.
