$stop and $finish in verilog

$stop - Pauses the simulation, so you can resume it by using fg command in linux. In this case lincense will not be released and process also is not killed, consuming memory.

$finish - Simulation is finished, so releasing of license and killing the process will be done.

$finish;
    Finishes a simulation and exits the simulation process.
$stop;
    Halts a simulation and enters an interactive debug mode.

$stop : Undesired termination of the simulation. All the system activities are suspended.

$finish : Used to relieve the compiler.

$finish exits the simulation and gives control back to the operating system.

$stop suspends the simulation and put interactive mode.
