Hardware interview practice
Drive random back-pressure
Drive ready high on approximately pct_ready percent of cycles to create randomized back-pressure.
Reviewed example
Work through one case
Input
pct_ready=25; random draws over four clock edges=[12,80,24,60] from 0..99Expected output
ready=[1,0,1,0]A fresh clocked draw is high only below the clamped 25-percent threshold; pct_ready 0 and 100 become deterministic low and high limits.
What to cover
Requirements
- Update ready on the interface clock.
- Accept a percentage from 0 through 100.
- Generate a fresh decision each cycle.
