When a problem is detected in a transaction, its poison signal is asserted. The poison signal propagates to the destination. For example, the interconnect poisons a transaction when an access is blocked by a protection unit or a parity error is detected. In some cases, the iPort receives a transaction that is already poisoned. The interconnect can signal this with an interrupt and allow it to propagate through to the ePort and out the switch.
