Clock Domain Crossing (CDC) refers to the challenge of transferring data between different clock domains in digital circuits, which can lead to metastability and data corruption if not handled properly. Effective CDC design ensures reliable data transfer using techniques like synchronization, handshaking, and FIFOs to mitigate these risks.
Concept
A synchronous circuit is a type of digital electronic circuit in which changes in the state of memory elements are synchronized by a clock signal. This ensures that all parts of the circuit transition simultaneously, reducing timing errors and making design and analysis more predictable.
Concept
Asynchronous circuits, unlike synchronous circuits, do not rely on a global clock signal for coordination, allowing them to potentially operate faster and with lower power consumption by processing inputs as soon as they arrive. However, they are more complex to design and verify due to the need to manage timing and synchronization issues internally.

Clock Tree Synthesis (CTS) is a crucial step in the digital design process, focused on distributing the clock signal evenly across a chip to minimize skew and ensure proper timing. It aims to balance the clock signal arrival times at all sequential elements, optimizing performance and power consumption in integrated circuits.
Concept
A D Latch, or Data Latch, is a digital storage device that captures and holds a data bit based on the state of an enable signal, allowing the data to pass through when the enable signal is active. It is fundamental in creating memory elements in sequential logic circuits, as it ensures data stability until the next clock cycle or enable signal change.
Concept
Edge triggering is a method used in digital circuits to initiate actions based on the transition of a clock signal, either from low to high or high to low. This technique ensures that changes in the state of a circuit occur only at specific moments, reducing the chance of errors caused by signal noise or glitches.
