7. Verification Algorithms in VLSI

Verification algorithms play a crucial role in the VLSI design flow by ensuring that designs meet functional and timing specifications. As the complexity of designs increases, both functional verification, which includes methods such as simulation and formal verification, and timing verification, which encompasses static timing analysis and delay propagation algorithms, become essential. Combining these verification methods aids in managing design complexity and ensuring performance without violating timing constraints.
