Python clock Examples

Example #1

File: test_core.py Project: jiankangren/fault

    class Main(m.Circuit):
        io = m.IO(clocks=ClocksT, count=m.Out(m.UInt[3]))
        count = m.Register(m.UInt[3])()
        count.CLK @= io.clocks.clk0
        io.count @= count(count.O + 1)

        tff = m.Register(m.Bit, has_enable=True)()
        tff.CLK @= io.clocks.clk0
        tff.CE @= m.enable(count.O == 3)
        io.clocks.clk1 @= m.clock(tff(tff.O ^ 1))

    assert isinstance(reset(bits(0, 1)), ResetType)
    assert isinstance(reset(uint(0, 1)), ResetType)
    assert isinstance(reset(sint(0, 1)), ResetType)

    assert isinstance(enable(bits(0, 1)), EnableType)
    assert isinstance(enable(uint(0, 1)), EnableType)
    assert isinstance(enable(sint(0, 1)), EnableType)
