How to link between Migen and Icarus Iverilog For simulation?? #122

Closed bhatmahadev6 closed 6 years ago

bhatmahadev6 commented 6 years ago

As given in docs i am not able to understand how to link to iverilog and simulate it further in gtkwave. I am not able to understand "make" commands in docs

The docs you are reading are out of date, there is the migen built-in simulator now that does not require an external simulator. If you do want to use Icarus, you can resurrect the old migen code.

from migen import * from migen.sim.vcd import VCDWriter, DummyVCDWriter class ORGate(Module): def init(self): self.a = Signal() self.b = Signal() self.x = Signal()

###

self.comb += self.x.eq(self.a | self.b)

dut = ORGate()

def testbench(): yield dut.a.eq(0) yield dut.b.eq(0) yield assert (yield dut.x) == 0

yield dut.a.eq(0) yield dut.b.eq(1) yield assert (yield dut.x) == 1

run_simulation(dut, testbench(),vcd_name="file.vcd")

i Ran this code ,But i am not getting any output,its just executing
