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.
