CLOCK TREE SYNTHESIS
Clock Tree Synthesis (CTS) is a crucial step in the digital design process of integrated circuits (ICs) and microprocessors. It involves the generation of a hierarchical network of clock distribution lines (commonly referred to as a "clock tree") to deliver a synchronized clock signal to all the sequential elements (flip-flops, registers, etc.) within the digital circuit.
The primary goal of Clock Tree Synthesis is to ensure that the clock signal reaches all parts of the chip with minimum skew and jitter, thereby maintaining proper synchronization and timing throughout the entire design. Clock skew refers to the variation in arrival times of the clock signal at different elements, while jitter refers to the variations in the period of the clock signal.
Key steps involved in Clock Tree Synthesis include:
Clock Tree Synthesis plays a crucial role in achieving reliable and high-performance digital designs, as proper clock distribution is essential for maintaining correct timing relationships and ensuring the overall functionality of the integrated circuit.
