verilog disable

In Verilog, the `disable` statement is used to terminate the execution of a particular `fork` or `join` block. It is typically used in conjunction with the `fork` statement to create concurrent processes in a testbench or within a procedural block. When the `disable` statement is encountered, it stops the execution of the current process and resumes execution from the point where the `join` statement is encountered.

Here's an example of how `disable` can be used:

initial begin
  fork
    // Process 1
    begin
      // Some code here
      disable fork; // Terminate all processes in this fork block
    end

    // Process 2
    begin
      // Some code here
      disable fork; // Terminate all processes in this fork block
    end
  join // Wait for all processes to terminate
  // Code after join
end

In the above example, when the `disable` statement is encountered, it terminates all processes within the `fork` block. The execution then continues from the `join` statement, where it waits for all processes to complete before proceeding further.
