An irreversible change in operation that is typically associated with permanent damage to one or more elements of a device or circuit (e.g., gate oxide rupture, destructive latch-up events).
NOTE The error is called "hard" because the data is lost and the device or circuit no longer functions properly, even after power reset and re-initialization.
Synonym for "macrocell".
Physical equipment, as opposed to programs, procedures, rules, and associated documentation. (Ref. ANSI X3.172.)
NOTE Contrast with "software".

NOTE The objective is to achieve faster simulation than can be achieved with software simulators.
The order and magnitude of the harmonic components.
Synonym for "instantaneous failure rate".
Synonym for "full-bridge (output)".
A current supplied to the device under test to cause the junction temperature to rise.
The product of heating current, IH, and heating voltage, VH; it causes the junction temperature of the device under test to rise.
The length of time electrical power, PH, is applied to the device under test to cause the junction temperature to rise.
The voltage across the device under test during the application of heating current, IH.
A separable element or integral part of the package that aids in dissipating the heat produced within the package.
A region of transition between two different semiconductor materials, usually with a negligible discontinuity in the crystalline structure.
NOTE A heterojunction can be between materials of the same conductivity type (isotype heterojunction) or of the opposite conductivity type (anisotype heterojunction).
See "humidity indicator card" and "integrated circuit, hybrid".
A description containing two or more nested levels of primitives.
The layout of a design that exists in multiple hierarchical levels.
The current into the output terminal with input conditions applied that, according to the product specification, will establish a high-impedance state at the output.
The current into an input terminal when a specified high-level voltage is applied to that input.
The most positive (least negative) value of high-level input voltage for which operation of the logic element within specification limits is to be expected.
The least positive (most negative) value of high-level input voltage for which operation of the logic element within specification limits is to be expected.
The current into the output terminal with input conditions applied that, according to the product specification, will establish a high level at the output.
The voltage level at an output terminal with input conditions applied that, according to the product specification, will establish a high level at the output.
A source driver whose primary connection within the integrated circuit is through an active device to a positive supply voltage.
In parallel addition, any procedure for speeding up the processing of carries. (Ref. IEC 824.)
EXAMPLE Standing-on-nines carry.
A graph obtained by dividing the range of the data set into equal intervals and plotting the number of data points in each interval against the interval number.
A signal that causes a central processing unit to stop its activity and to relinquish control over the bus until the signal is removed. (Ref. IEC 824.)
The time interval during which a signal is retained at a specified input terminal after an active transition occurs at another specified input terminal.
NOTE 1 The input hold time is the actual time interval between two signal events and is determined by the system in which the digital circuit operates. A minimum value is specified that is the shortest interval for which correct operation of the digital circuit is to be expected.
NOTE 2 The input hold time may have a negative value, in which case the minimum limit defines the longest interval (between the release of the signal and the active transition) for which correct operation of the digital circuit is to be expected.
Synonym for "valid time, output data-".
A depression in the surface, the bottom of which is not visible.
(2) (in a semiconductor material): A mobile vacancy in the electronic valence structure that acts like a positive electron charge with a positive mass.
IEEE Std 100
A programming system as described in the purpose and scope of JESD32.
Synonym for full-bridge (output).
NOTE The term "H switch" is usually applied to forward-off-reverse-switching (using one or two three-state outputs) or forward-reverse-switching applications.
A card on which a moisture-sensitive chemical is printed such that it will undergo a significant, perceptible change in color (hue), typically from blue (dry) to pink (wet) when the indicated relative humidity is exceeded.
NOTE The HIC is packed inside the moisture-sensitive bag, along with the desiccant, to aid in determining the level of moisture to which the moisture-sensitive devices have been subjected.
See "integrated circuit, hybrid".
Synonym for "integrated circuit, hybrid".
The difference between the positive-going and the negative-going input threshold voltages.
Printed board resins plus reinforcement matrix that contain maximum total halogens of 1500 ppm with less than 900 ppm bromine and less than 900 ppm chlorine (ref. IEC 61249-2-21).
A material of uniform composition throughout that cannot be mechanically separated into different materials.
NOTE 1 Examples of “homogeneous materials” are certain types of plastics, ceramics, glass, metals, alloys, paper, board, resins, and coatings.NOTE 2 Methods of mechanical separation include cutting, crushing, grinding, and abrasive processes.
