7. Clock Tree Synthesis and Routing

Clock Tree Synthesis (CTS) and routing are essential processes in VLSI design, ensuring effective clock signal distribution and optimal interconnections across chip components. The goals of CTS include minimizing skew and balancing the clock tree, while routing aims to connect components efficiently to achieve design performance. Advanced algorithms and tools are critical in addressing the challenges posed by complex designs, such as timing closure and routing congestion.
