Parallel Test Vector
Application
Use of internal registers to hold and release a full set of test vectors (e.g.,
20 for a 10-input 10-output device) at once. In contrast to serial
application, parallel application does not require accommodations for
clocking contention, and parallel better matches in-circuit PLD operation
and board test suites.
Part Number
The number on the device. For example if you are using an Intel 27C256,
then the part number of the device is 27C256.
Pin-driver
The electric circuit reading or applying voltage and current pulses to the
individual pin of a device, for programming or testing. See also Universal
Pin Driver.
PGA
An acronym for Pin Grid Array, a type of device package. Usually a
square device with one side populated with small pins as leads.
PLCC
An acronym for Plastic Leaded Chip Carrier, a device package with J-
shaped leads extending from four sides downward, used for surface
mount applications.
PLD
An acronym for Programmable Logic Device, a type of programmable
integrated circuit. Architectures range from very simple to very complex.
Most PLDs contain two levels of logic: an AND array followed by an OR
array.
PROM
An acronym for Programmable Read-Only Memory. A device with fixed
AND and programmable OR arrays. This is a slightly different
architecture from an FPLA or a PAL.
Program
The controlled application of electrical pulses to program specific fuses or
cells.
Program Device
A device operation that copies device data into a socketed device. The
programming is done according to the programming algorithm selected
in the select device stage. The programming operation can also include a
verify operation.
Program Security Fuse
A programming parameter that enables/disables the programming of the
device’s security fuse.
Program Signature
Available on only a few devices, the Program Signature is a user-
definable field that allows the user to program data into the program
signature array. For example, the Program Signature could contain the
revision level or modification date of the data in the remainder of the
device.
Programmable Integrated
Circuit
One of the four basic categories of ASICs: the other three being gate
arrays, standard cells, and full custom devices. PICs are ICs that are user
configurable. PLDs and PGAs are examples of programmable integrated
circuits.
