In this way, what is blocking and nonblocking in Verilog?
Well, "=" is blocking assignment and "<=" is nonblocking assignment. "=" executes code sequentially inside a begin / end, whereas nonblocking "<=" executes in parallel. After all, you can make blocking assignments with assign statements outside of always blocks, and those all run in parallel.
Subsequently, question is, what is the difference between asynchronous and non blocking? An asynchronous call requests a transfer that will be performed in its whole(entirety) but will complete at some future time. Non-blocking: This function won't wait while on the stack. Synchronous is defined as happening at the same time. Asynchronous is defined as not happening at the same time.
Hereof, what is blocking in Verilog?
A blocking assignment gets its name because a blocking assignment must evaluate the RHS arguments and complete the assignment without interruption from any other Verilog statement. The assignment is said to "block" other assignments until the current assignment has completed.
What is a blocking operation?
Blocking refers to operations that block further execution until that operation finishes. In the given example, localStorage is a blocking operation as it stalls execution to read.
