onTAP
Component Descriptions:
Test Development System (Automatic test generation
of TAP integrity and interconnect tests based on project
netlists and BSDL files. Includes BSDL syntax checking,
BSDL/CKT matching, jumper management, pin constraints,
Make program for adaptor files, testability information,
parallel cable selection, Test Palette selections, diagnostic
messages, test reports and tool suites, user-defined tests,
script and command files, development and eebug tools,
virtual pints, transparency and Bus Management. Outputs
SVF test format files.)
Run-time System and Scan Sequencer (Runs tests
and presents diagnostics independently of Test Development;
Includes breakpoints, loop control and a boundary scan
simulator for program debug, plus a screen for manufacturing
test and burn-in.)
Netlist Browser, Application Signal Sampling Viewer
and Pin Wiggler (Users may browse through net lists
and may sample and view system level application signals,
based on JTAG SAMPLE instruction, at any circuit location.
A pin wiggler enables user to set any pin output value
and to read pin input values.)
Memory and Cluster Test (Serializes and scans
vector tests through boundary scan devices and chains.
Vector tests for logic/memory devices are created with
high-level, reusable DTS program models which may be tailored
for application-specific purposes.)
DTS - Digital Test Syntax (A high level test programming
language providing program flow control, direct pin control,
variables, sub-routines and manipulation of pin groups.)
FLASH Programming (Uses the Memory and Cluster
Test option, and DTS to program FLASH; especially suited
for FLASH boot code.)
Serial Vector Format (SVF - an industry standard
representation of boundary scan data extended for use
with onTAP.)
Virtual Pins, Transparency and Bus Management (Virtual
pins allows onTAP to "reach through" resistors and
buffers to connect scannable and cluster pins. Virtual Pins
also dynamically manages direction and enable control pins when
accessible.
The Manufacturing Test Only screen provides the same
access to all test and diagnostic information as the full development
system, but restricts use to the test screens and restricts
access to menu items that could alter the tests.
