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.

Firmware Keys and STOP

Commands

The ProMaster 2500 is normally operated in remote mode using the

TaskLink software. Some of the firmware key commands listed in this

Appendix are active only while the handler is in local mode. To execute a

firmware key command from one of the handler menus, perform the

following steps:

1. Put the handler into local mode by pressing the

LOWER CASE

keys.

2. Go to the appropriate menu and press the key sequence to access the

display.

3. Enter the new numeric value or answer the prompt from the 2500’s

keyboard and press

START

The 2500 supports a second set of commands known as STOP commands,

because the commands are entered after pressing

STOP

to pause the

2500. These differ from the firmware key commands because they can be

used while processing devices so you do not have to exit the current Task.
