使用 cocotb 在列表中生成一个协程

Question

我有一个协程，它等待一个事件被设置：

@cocotb.coroutine

def wb_RXDR_read(self):

    """ waiting util RXDR is read """

    if not self._RXDR_read_flag:

        while True:

            yield self._RXDR_read_event.wait()

            break

我想在超时的情况下“屈服”。然后要做到这一点，我这样做了：

        RXDR_timeout = Timer(250, units="us")

        ret = yield [RXDR_timeout, self.wb_RXDR_read()]

        if ret == RXDR_timeout:

            self._dut._log.error("Timeout on waiting RXDR to be read")

            raise TestError()

但我收到此错误：

2ns ERROR    Coroutine i2c_write yielded something the scheduler can't handle

                      Got type: <type 'list'> repr: [<cocotb.triggers.Timer object at 0x7f2098cb1350>, <cocotb.decorators.RunningCoroutine object at 0x7f2098cb1610>] str: [<cocotb.triggers.Timer object at 0x7f2098cb1350>, <cocotb.decorators.RunningCoroutine object at 0x7f2098cb1610>]

                      Did you forget to decorate with @cocotb.coroutine?

我的协程用@cocotb.coroutine 装饰。如果我单独屈服它有效：

yield self.wb_RXDR_read() # <- that works

但我不能把它放在一个列表中。是否可以将协程放在一个列表中以像 unix select() 那样阻塞？还是保留给 Trigger 类？
