Thread-full API
==========================================


In SpinalSim, you can write your testbench by using multiple threads in a similar way to SystemVerilog, and a bit like VHDL/Verilog process/always blocks. 
This allow to write concurant tasks of your testbench and to move/wait in the simulation time with a fluant API.


Fork and join simulation threads
--------------------------------

.. code-block:: scala

   //Create a new thread
   val myNewThread = fork{
     //New simulation thread body
   }

   //Wait until `myNewThread` is execution is done.
   myNewThread.join()

Sleep and waitUntil
-------------------

.. code-block:: scala

   //Sleep 1000 units of time
   sleep(1000)

   //waitUntil the dut.io.a value is bigger than 42 before continuing
   waitUntil(dut.io.a > 42)
