### Q: What are the key benefits of using a dedicated Clock Management block in FPGA/ASIC designs?
**A**: A dedicated Clock Management block ensures precise clock generation, distribution, and control, reducing timing errors, minimizing power consumption through gating, and improving overall system reliability and performance in semiconductor devices.

### Q: How does Clock Management improve power efficiency in electronic products?
**A**: Clock Management incorporates clock gating cells to disable clock signals to inactive circuit blocks, significantly reducing dynamic power consumption. This is critical for battery-powered devices and high-performance computing where power efficiency is paramount.

### Q: What role does the Phase-Locked Loop (PLL) play in Clock Management systems?
**A**: The PLL generates stable, high-frequency clock signals from a reference clock, enables frequency multiplication/division, and provides phase alignment. It's essential for synchronizing operations, reducing jitter, and supporting various clock domains in complex semiconductor designs.
