Course Overview

 

This course features 100 carefully crafted multiple-choice Qualcomm ASIC Design interview questions, each accompanied by a detailed explanation. Questions are modeled after actual design problems Qualcomm engineers face and span RTL implementation through physical design handoff.

 

Each question is designed to assess:

• RTL coding clarity and synthesis-readiness
• Timing, area, and power trade-offs
• CDC handling, multi-clock domain planning
• Real-world debugging and functional correctness under constraints

 

These questions closely mirror the Qualcomm interview flow, including technical phone screens, whiteboard problem-solving, and architecture-level discussions.

Topics Covered

 

The Qualcomm ASIC Design interview questions span all relevant topics required for modern ASIC design roles:

 

RTL Design and Microarchitecture

• Writing synthesizable and efficient SystemVerilog/Verilog modules
• Implementing FSMs, datapaths, and register banks with minimal logic depth
• Understanding latch inference, reset logic, and inferred memories

 

Synthesis and STA Fundamentals

• Analyzing setup and hold violations
• Writing constraints (SDC), creating false and multicycle paths
• Reading timing reports and identifying critical paths

 

Clocking and CDC Handling

• Safe synchronization techniques for multi-clock domain signals
• Designing CDC interfaces using handshakes or synchronizer chains
• Using assertions to check metastability and CDC errors

 

Low-Power Design Techniques

• Clock gating insertion and enable control logic
• Power domains and isolation strategies using UPF/CPF
• Retention register handling and power state transitions

 

Formal Verification and Linting

• Common lint issues (unconnected ports, multiple drivers, inconsistent resets)
• Using formal properties to verify design assumptions and corner cases
• Interpreting CDC, reset, and logic equivalence checks (LEC)

 

IP Integration and SoC Design

• Integrating AXI, AHB, and proprietary IPs into larger subsystems
• Resolving bus contention, protocol mismatches, and arbitration logic
• Ensuring modularity and reusability in configurable SoC blocks

 

Physical-Aware RTL and ECO Flows

• Designing RTL with floorplanning and P&R feedback in mind
• Understanding congestion hotspots and ECO implications
• Modifying RTL for post-silicon bug fixes and timing pushes
