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.
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.
Programmable Built-In Self-Test (PBIST) is a memory DFT feature that incorporates all the required test systems into the chip itself. The test systems implemented on-chip are as follows: algorithmic address generator; algorithmic data generator; program storage unit; loop control mechanisms
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.
On an IBM mainframe, a power-on reset (POR) is a sequence of actions that the processor performs either due to a POR request from the operator or as part of turning on power. The operator requests a POR for configuration changes that cannot be recognized by a simple System Reset .
A diagnostic program (also known as a test mode) is an automatic computer program sequence that determines the operational status within the software, hardware, or any combination thereof in a component, a system, or a network of systems. Diagnostic programs ideally provide the user with guidance regarding any issues or problems found during ...
