Example from the web:

import spatial.dsl._

@spatial object HelloSpatial extends SpatialApp {
  def main(args: Array[String]): Void = {
    // Create ArgIn
    val x = ArgIn[Int]
    
    // Set `x` to the value of the first command line argument
    setArg(x, args(0).to[Int])
    
    Accel {
      // Create 16x32 SRAM and a Register
      val s = SRAM[Int](16,32)
      val r = Reg[Int]
      
      // Loop over each element in SRAM
      Foreach(16 by 1, 32 by 1){(i,j) => 
        s(i,j) = i + j
      }
      // Store element into the register, based on the input arg
      r := s(x,x)

      // Print value of register (only shows in Scala simulation)
      println(r"Value of SRAM at (${x.value},${x.value}) is ${r.value}")
    }

  }
