Study path
Qualcomm-style ASIC interview preparation
Practice the interface-heavy path from RTL and CDC through timing constraints, protocol behavior, arbitration, QoS, firmware, and architecture. State clock relationships, ownership, ordering, and backpressure before choosing the mechanism.
Support the choice with assertions, reference models, timing reports, or performance budgets, especially for shared links and power-aware boundaries. These independent exercises do not describe Qualcomm's official interview process.
