Product Overview 1-1
Introduction
The NetUSB-1149.1, NetUSB-1149.1/E and NetUSB-1149.1/SE High-Speed Boundary-Scan
(JTAG) Controllers are members of the Corelis ScanPlus™ and ScanExpress™ family of scan-
based test, analysis, and diagnostic tools. They are managed by a PC host, which is linked with
either a USB2.0 (compatible with USB1.1) interface, or over 10/100 Ethernet network. Under host
direction, the NetUSB-1149.1, NetUSB-1149.1/E and NetUSB-1149.1/SE test one or more IEEE
Standard 1149.1 compatible target board (UUT). The NetUSB-1149.1 family is designed to control
the operation of one or more IEEE Standard 1149.1 boundary-scan (JTAG) test access ports
(TAPs) by generating the proper signals as dictated by software. This provides stimulus and accepts
response signals of the attached customer target circuits, enabling their testing and/or programming.
This capability is supported by memory-behind-the-pin architecture driving scan operations at
continuous JTAG clock (TCK) speeds of up to 70 MHz.
The NetUSB-1149.1 family facilitates software-controlled boundary-scan operations per the IEEE
Standard 1149.1. It provides command visibility to the target’s Test Access Port (TAP), accessing
device internal registers and on-chip debugger, verifying PCB interconnects, performing functional
testing, and debug without manual probing. The JTAG interface provides access to internal device
functions that are not accessible via external probing, enabling fault isolation within the device itself.
The JTAG interface also enables programming target FLASH and CPLD devices, as well as data
downloading and uploading to and from the target memory devices.
Either of the NetUSB-1149.1 type controllers can also be used to perform microprocessor
emulation via that device’s JTAG port. This facilitates firmware development by providing single-
step, break, and content update/visibility access.
There are three models of this product. The basic NetUSB-1149.1 (no /E or /SE suffix) has
scanning access through a single SCSI II 68-pin connector. This supports a single direct target TAP
operation with the appropriate cable. With a different cable type, it implements the Corelis
ScanExpress expansion bus to operate a remote intelligent pods, such as the ScanTAP-4, ScanTAP-
8, ScanTAP-32, or ScanHUB (in turn accessing more of the ScanTAP intelligent pods). The
NetUSB-1149.1/E and NetUSB-1149.1/SE models are capable of scanning multiple TAPs
concurrently when used with the ScanExpress Runner software which is sold separately.
The NetUSB-1149.1/E model is similar to the NetUSB-1149.1 above, but has the equivalent of a
ScanTAP-4 remote pod built-in as an integral resource, enabling it to operate up to four boundary-
scan TAPs simultaneously. Note that the external SCSI connector on this unit is not used and no
external ScanTAP pod is required.
The NetUSB-1149.1/SE model is similar to the NetUSB-1149.1/E except that it contains a built in
ScanTAP-8 pod as an integral resource, enabling it to operate up to eight target TAPs
simultaneously, with no other external equipment And therefore the NetUSB-1149.1/SE model
does not use the external SCSI connector.

1-4 Product Overview
What Is IEEE Standard 1149.1?
The IEEE Standard 1149.1 Test Access Port (TAP) and boundary-scan architecture enable control
of an IC, board, or system, via a standard four-signal interface. Each IEEE-1149.1 compliant IC
incorporates a feature known as boundary-scan, which ensures that a JTAG controller can control
and observe each functional pin of the IC via the JTAG interface. A controller can load test, debug,
or initialization patterns serially into the appropriate IC(s) via the IEEE-1149.1 TAP. Thus, even
with limited physical access, a user can observe or control IC, board, or system functions.
Two main elements comprise the IEEE Standard 1149.1 test Port: a Test Access Port (TAP), which
interfaces internal IC logic with the external world via a four-signal (optionally five-signal) Port as
shown in Figure 1-4,and a boundary-scan architecture, which defines standard boundary cells that
drive and receive data at the IC pins. IEEE Standard 1149.1 also defines both mandatory and
optional OPCODES and test features. The test Port signals are: Test Clock (TCK), Test Mode
Select (TMS), Test Data In (TDI), Test Data Out (TDO), and the optional Test Logic Reset (TRST).
The IEEE-1149.1 Test Access Port
Interface (TAP) consists of four
required signals:
Test Mode Select (TMS)
Test Clock (TCK)
Test Data In (TDI)
Test Data Out (TDO)
A fifth signal is defined as optional:
Test Reset (TRST*)

Features of the NetUSB-1149.1
The Corelis NetUSB-1149.1 family includes the NetUSB-1149.1, NetUSB-1149.1/E and the
NetUSB-1149.1/SE models. It is a high performance boundary-scan test and programming
controller that can access devices, boards or systems compliant with IEEE Standard 1149.1. It has
two distinct host PC access ports for easy deployment, including USB 2.0 (also compatible with
USB 1.1) and Ethernet 10/100baseT, only one of which manages operations at a time. If a host
connection is made both at the Ethernet and USB ports, the USB access controls operation.
These scan controllers drive one or more JTAG boundary-scan chains (TAP), depending on module
type and/or attachment of external pods (ScanTAP-x). Included per TAP are a number of input
and/or output discrete signals available to test or control non-boundary-scan areas of the unit under
test (UUT) target. They facilitate non-scanned target FLASH write pulsing and FLASH ready/busy
line sensing to greatly reduce the scanning cycles required for such devices. With its software-
controlled voltage translating logic, the NetUSB-1149.1 family can test low voltage as well as
standard TTL/CMOS systems.

Product Overview 1-5
The NetUSB-1149.1 family contains several performance enhancing functional sections aimed at
increasing test vector throughput. Key elements include the TAP controller, and the memory
resources that support it. The large on-board memory provides scan data storage and can often
hold the data for an entire scan, maximizing performance and enabling real-time operations.
A test system accesses the TAP controller and its associated memory by host management
communications. This is supported by the high data rate of the USB 2.0 or Ethernet 10/100baseT
links, regardless of actual TCK test clock speeds. The ability to download information into these
memory elements decouples the scan operations from the host software. A state machine that
contains status and control registers accessible to the host controls all functions of the NetUSB-
1149.1 controllers.
The NetUSB-1149.1 family TAP controllers contain special autonomous hardware accelerator
mechanisms to greatly increase performance where scan patterns repeat numerous times. This
applies to target download/upload sequence loops, which convey large data blocks. As a result, time
consuming tasks such as flash programming and emulator data transfers are more efficient for a
given clock rate. This mechanism off-loads the host interaction requirements by generating repeated
vectors internally, using host pre-loaded memory information. After host initialization, this mode of
operation results in continuous, maximal scanning rates at all clock frequencies. The only exception
occurs when the target paces the sequence by indicating a non-ready completion of data transfer,
requiring a re-scan of the target’s status. When not in this special autonomous mode, the scan
stream bursts at the programmed TCK rate, as paced by the flow of vector bits from the host.
Another performance enhancement provides hardware expected-value verification of scanned-back
data at programmable chain positions. Thus, the target output stream is evaluated for each TAP
without host intervention and accompanying process delays. This also supports the above
autonomous operation enabling the scanning sequence to loop and rescan until the desired feedback
is supplied, without host intervention.
A programmable, time delay skew compensation mechanism supports the NetUSB-1149.1 family
high clock rates. This accommodates the returned target scan bit delays due to signal travel time
down and up the cables. It can also adjust for a target’s on-board TCK-to-TDO response delay.
An auxiliary feature of the NetUSB-1149.1 family is the target power-shorted detector for two
voltages. With the target un-powered, this mechanism effectively measures the impedance of the
target load for each of two possible connected voltages, determining if a short exists (some
unacceptably low impedance). If this impedance is less than about 1 ohm (about an 11 watt target
or more at 3.3V, for example), it is deemed shorted and reported to the user.
Adjustable Voltage Interface
The software-programmable voltage level of the discrete I/O and TAP interface can be set to any
voltage between 1.25 V and 3.30 V with 0.05V resolution .
Discrete Input/Output Signals
SCSI Connector Direct TAP Port
The NetUSB-1149.1 family offers 3 discrete input and 5 discrete output signals on the SCSI
connector (front panel). They are driven or sensed under host software control, in coordination
with the scanning operation. All of these signals track the software adjustable interface voltage level.
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

1-6 Product Overview
One of the discrete inputs is designated a FLASH ready/busy handshake input, enabling the direct
(non-scanned) pacing of device programming. This avoids the need to scan in this information,
speeding up the overall process.
One of the discrete outputs is dedicated as an external write pulse signal. This can reduce cycle
times by directly driving (non-scanned) the FLASH device, without the need to scan it out.
The other 4 outputs are generally useful for providing control functions on the user target system
such as reset, power control, and disable/enable signals for non-boundary-scan target devices.
Further, the additional 2 inputs enable host sensing of the target as a pacing method.
If open-collector mode is selected, the external write and two of the general discretes (porta_out0,
and porta_out1) operate that way, while the other two general discrete output will float. Otherwise,
all 5 outputs will operate as adjustable voltage totem-pole.
Built-in or Remote Pod TAP Ports
The NetUSB-1149.1 with an external pod (ScanTAP-x), the NetUSB-1149.1/E with 4 built-in TAP
ports or the NetUSB-1149.1/SE with 8 built-in TAP ports provide 3 discrete bi-directional
input/output signals. These are independently direction steer-able under software control, as well as
capable of open-collector (open-drain) drive operation. Here also, one can function as the FLASH
external write strobe and another as the FLASH ready/busy sense signal, as above, for accelerated
operations.
USB Port Interface
The NetUSB-1149.1 family USB interface complies with the version 2.0 standard with backward
compatibility to version 1.1 (excluding low speed). Speed adjustment is automatic per the standard.
The hot-plug feature of this standard is fully supported such that attachment is easily made to a
running PC, which will automatically sense its presence. For optimal performance, the user is
strongly recommended to utilize a host PC with a USB 2.0 port. This interface serves as one of two
host access points, only one of which operates the controller at a time.
Ethernet Port Interface
This serves as an alternate host access point to the USB interface. The NetUSB-1149.1 family
Ethernet interface supports 10/100baseT with automatic speed switching. It is IEEE 802.3u
100BASE-FX compatible.
RS-232 Serial Maintenance Port Interface
THIS IS FOR FACTORY USE ONLY … As delivered, this port is disabled on all
NetUSB-1149.1 products.
The NetUSB-1149.1 family serial port is provided for trouble shooting purpose only at the factory.
During normal operation, users should not need to access this port. Its connector is a female DB9,
wired with a DTE pin-out. The default communications parameters are 115200 baud, 8 bits, no
parity, 1 stop bit, XON/XOFF flow control. This port should be connected to a PC on COM1
using a NULL modem cable.

Programmable Clocks
The NetUSB-1149.1 family’s programmable TCK output to the IEEE Standard 1149.1 compatible
target system can be generated with a wide range of frequencies using on-board clock generation
circuitry. A programmable Phase Locked Loop (PLL) and counter dividers enable both an agile and
fine resolution set of rates. See Table 1-2 for the set of programmable values.

Other Features of the TAP Ports
Besides the direct target TAP operation, NetUSB-1149.1 (not the NetUSB-1149.1/E or NetUSB-
1149.1/SE) can operate a remote pod, such as the Corelis ScanTAP-x or ScanHUB family. By
special differential signaling methods, and automatic propagation delay compensation, such remote
pods can employ cables up 30 feet in length, with no additional hardware, at full TCK rate
performance.
The 8 TAPs of the NetUSB-1149.1/SE, the 4 TAPs of the NetUSB-1149.1/E, or the remote pod
TAPs driven by the NetUSB-1149.1 can be programmed to daisy-chain sub-sets of the TAP ports
into single chains. During gang (concurrent) TAP operations, all targets can be scanned
simultaneously. While scanning, each TAP returns scanned in information that is compared against
expected patterns for verification and possible mismatch error detection. An unexpected pattern on
any individual TAP will be logged, but need not necessarily stop the scan session for the others.
This method supports rapid FLASH content validation, for example, for a large set of targets.
Failed targets are isolated while the checking the others continues to completion.
The JTAG scanning signals can be programmed to transition at fast or slow rates, although by
default, the software selects this based on requested TCK clock rate. This feature has some

limitations due to adjustable voltage level and available configurations for discrete I/O lines. This is
offered to aid in system signal noise management.
Another significant feature is that each TAP can detect a target power short to ground for up to 2
voltages per TAP, allowing the ScanTAP-4 to discover potentially damaging conditions before the
target system(s) is powered up.
