- **Caution**: 
- **Caution**: 

### Q: What are the primary components of a Configurable Logic Block?
**A**: A Configurable Logic Block typically consists of a Look-Up Table (LUT) for logic implementation, flip-flops for data storage, multiplexers for signal routing, and configuration memory for programming.

### Q: How do Configurable Logic Blocks differ between FPGAs and ASICs?
**A**: In FPGAs, CLBs are pre-fabricated and reprogrammable via configuration memory, while in ASICs they are custom-designed and fixed during manufacturing for optimized performance and power efficiency.

### Q: What materials are used in manufacturing Configurable Logic Blocks?
**A**: CLBs are primarily fabricated using silicon as the semiconductor substrate, copper for interconnects, and silicon dioxide for insulation between layers in integrated circuits.
