ASICs vs FPGAs

Understanding FPGA and ASIC trade-offs in hardware design

This question tests your grasp of the practical engineering trade-offs between two fundamentally different approaches to implementing digital logic: field-programmable gate arrays (FPGAs) and application-specific integrated circuits (ASICs). Both are used in high-performance computing and trading systems, but they serve different constraints and use cases.

To reason through this correctly, you need to understand what FPGAs actually do well—reconfigurability, rapid iteration, lower upfront design cost, and shorter time-to-market—versus where ASICs have the advantage: power efficiency, speed, integration density, and cost per unit at scale. The question asks you to identify which property is not a genuine FPGA strength, which requires distinguishing real benefits from misconceptions or domain-specific advantages that actually favour ASICs.

• Reconfigurability and design flexibility
• Manufacturing lead time and NRE costs
• Power consumption and thermal considerations
• Per-unit cost dynamics at different production volumes
