Programmable built-in self-test (pBIST) Memory built-in self-test (mBIST) - e.g. with the Marinescu algorithm [2] Logic built-in self-test (LBIST) Analog and mixed-signal built-in self-test (AMBIST) Continuous built-in self-test (CBIST, C-BIT) Event-driven built-in self-test, such as the BIST done to an aircraft's systems after the aircraft lands.
A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. [ 1 ] POST processes may set the initial state of the device from firmware and detect if any hardware components are non-functional.
A pointing stick (or trackpoint, also referred to generically as a nub or nipple) is a small analog stick used as a pointing device typically mounted centrally in a computer keyboard. Like other pointing devices such as mice , touchpads or trackballs , operating system software translates manipulation of the device into movements of the pointer ...
A drive that implements S.M.A.R.T. may optionally implement a number of self-test or maintenance routines, and the results of the tests are kept in the self-test log. The self-test routines may be used to detect any unreadable sectors on the disk, so that they may be restored from back-up sources (for example, from other disks in a RAID). This ...
The main advantage of LBIST is the ability to test internal circuits having no direct connections to external pins, and thus unreachable by external automated test equipment. Another advantage is the ability to trigger the LBIST of an integrated circuit while running a built-in self test or power-on self test of the finished product.
The most common method for delivering test data from chip inputs to internal circuits under test (CUTs, for short), and observing their outputs, is called scan-design. In scan design, registers ( flip-flops or latches) in the design are connected in one or more scan chains , which are used to gain access to internal nodes of the chip.
The BIOS in older PCs initializes and tests the system hardware components (power-on self-test or POST for short), and loads a boot loader from a mass storage device which then initializes a kernel. In the era of DOS , the BIOS provided BIOS interrupt calls for the keyboard, display, storage, and other input/output (I/O) devices that ...
A cyclic redundancy check (CRC) is a non-secure hash function designed to detect accidental changes to digital data in computer networks. It is not suitable for detecting maliciously introduced errors.
