PLD
An acronym for Programmable Logic Device. A particular type of
programmable integrated circuit. Architectures range from being 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.
Process
A series of device related operations are combined to form a process for
each Task. The device related operations that can be selected are: Blank
Check, Illegal Bit Check, Program, Verify, and Label.
Programmable Integrated
Circuit (PIC)
One of the four basic categories of ASICs — the other three being gate
arrays, standard cells, and full custom devices. PICs are user
configurable. PLDs and FPGAs are examples of programmable integrated
circuits.
Programming Block
The socket on the programming module where the 2500 inserts devices
for programming. The module’s contacts are mounted in the
programming block.
Programming Electronics
(PE)
The electronic assembly in the 2500 base that controls the electrical
signals required to perform device test, program, and verify operations.
Often referred to as “PE” in the documentation.
Programming Module
The interface between the 2500 programming electronics and the device.
The programming module routes signals from the pin driver head to the
device pins.
Programming Station
The cut-out portion of the main plate where the programming module is
installed.
Remote Mode
One of two system operation modes for the ProMaster 2500. In this mode,
the 2500 is configured to respond to commands sent by TaskLink. This is
the primary operating mode for the ProMaster 2500. The other system
operating mode is called Local mode.
Security Fuse
A location in a programmable device that, when programmed, secures
the device from readback: the data in the device becomes unreadable.
Security Fuse Data
The data programmed or that will be programmed into the device’s
security fuse.
Security Option
A programming parameter defined in the Task the enables or disables the
programming of the device’s security fuse.
Select Device
A procedure that tells the 2500 programming electronics what device you
will be using. You select a device by choosing the manufacturer and
device part number off a list on TaskLink’s screen.
Self-test
A command that tests various circuits and subsystems in the 2500
programming electronics, verifying proper operation or isolating possible
problem areas.

Serial Vector Test
A device test that applies test vector input states serially, starting with pin
one and stepping through the remaining pins. This test is a diagnostic
tool designed to help debug and classify test vector failures. Specifically,
this test is designed to isolate test vectors that are sequence dependent.
SMT
An acronym for Surface Mount Technology, an approach to designing
and manufacturing electronic circuit boards where the component leads
are mounted on the surface of the board rather than inserted through
holes in the board.
SOIC
An acronym for a Small Outline Integrated Circuit. These are surface
mount devices (see SMT) with two parallel rows of gull-wing leads.
SPA
An acronym for Squirt Pin Array. These are the spring-loaded gold pins
located in the programming station. Programming signals from the 2500
programming electronics pass through these pins to the programming
module circuit board, and through the programming module contacts to
the device.
STOP Commands
A set of commands entered from the front panel that allow the operator
to change operating parameters without having to exit a running Task.
Stop Guide
The end of the input track that each device rests against before the beam
picks it up.
Structured Test Vectors
A string of test conditions applied to a PLD in a programmer/tester to
stimulate inputs and test outputs to ensure functionality. A test vector is
one such string — for example, 20 characters for a 20-pin PLD, with 10
input signals and 10 expected outputs.
Sumcheck
A four to eight digit hexadecimal number that, when compared to the
original data, allows you to verify that a copy of the data matches the
original data. The length of the sumcheck is a user selectable parameter in
TaskLink.
Test Vector
Test vectors functionally test the device, using structured test vectors
stored in memory or in a disk file.
Translation Formats
A form of transmission protocol, these formats are used when
transferring data between the 2500 and the PC or a host computer. The
different formats represent different ways of encoding the device data in
a data file. The data file could contain the fuse pattern for a logic device or
the data for a memory device.
Upload Data
A file transfer operation that involves sending data from the 2500 to a PC
or host computer.
Verify Device
A device operation that compares data in a programmed device with data
in RAM or in a disk file. With logic devices, verifying can also include
functional testing. Verify is an automatic part of the program operation,
but additional verify operations can provide useful information about
any errors.
Verify Pass
A verify pass is a pass through a device at a specified Vcc to see if the
device programmed properly. The pass is usually done once at 5V. The
pass can also be done twice, with the first pass at 5.5V and the second
pass at 4.5V.

Wildcard
A global search character used to speed the search for a specific device
name or file name in TaskLink. When entering filenames, a wildcard
represents one or more characters in a filename. For example,
27*.dat
represents both
27512.dat
and
27128.dat
.
Yield
The percentage of successfully programmed devices.
