SystemLua

A lua version of SystemC

SystemLua is a lua version of SystemC. It can co-simulate with verilog by VPI.

Example

Standalone

-- file test.lua

require "sl_core"

run(function()
  always(signal("foo").anyedge, function ()
    info("foo")
  end)
  always(3, function ()
    info("bar")
  end)
  initial(function ()
    signal("foo"):write(1)
    wait(1)
    signal("foo"):write(0)
  end)
end, 10)

Co-simulation

-- file test_pli.lua

bind_signal("clk", "tb.clk")
bind_signal("foo", "tb.foo")

local i = 0

always(signal("clk").anyedge, function()
  signal("foo"):write(i)
  i = i + 1
  if i >10 then
    sim_finish()
  end
end)

signal("foo"):write(1)

// file tb.v

module tb();
  reg clk;
  reg foo;
  always #1 clk <= ~clk;
  always@(foo) begin
    $display("%0d foo", $time());
  end
  initial begin
    clk = 0;
    $sys_lua("test_pli.lua");
    #100 $finish();
  end
endmodule
