The difference between always and initial blocks in SystemVerilog

In SystemVerilog, the difference between always and initial blocks lies in their execution time.

The always block is used for describing processes that should trigger continuously based on specific events or conditions. It is mainly used for modeling sequential logic.

On the other hand, the initial block is used for executing statements only once at the beginning of the simulation or whenever the module containing it is instantiated or re-initialized.

Understanding the nuances between always and initial blocks is crucial for writing efficient and correct SystemVerilog designs.
