In semiconductor devices, problems in the device package may cause failures due to contamination, mechanical stress of the device, or open or short circuits. Failures most commonly occur near the beginning and near the ending of the lifetime of the parts, resulting in the bathtub curve graph of failure rates.
Often, bugs come about during coding, but faulty design documentation may cause a bug.

In an embedded system, the software is often modified to work around a hardware bug since it's cheaper than modifying the hardware.
