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

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

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

Sleep and waitUntil

//Sleep 1000 units of time
sleep(1000)

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