Corelis Legacy
JTAG Boundary-Scan Controllers
Corelis has developed a wide range of high-performance
boundary-scan controllers that are compatible with buses
such as USB 2.0, PCI, PCI Express, PXI/cPCI, Ethernet, VME,
and VXI. Most of Corelis' boundary-scan controllers operate
up to 80MHz sustained TCK frequency. This wide choice of
platforms allows greater flexibility to meet specific price
and performance criteria for a given application while
maintaining complete software transportability across all
hardware platforms. The table below lists both current and
legacy JTAG controllers offered by Corelis. A brief
description of each controller follows. For complete
information on the controllers, please refer to the detailed
datasheets.

USB-1149.1/E
The USB-1149.1/E™ is a high-performance
plug-and-play IEEE-1149.1 Boundary-Scan (JTAG) controller for the
Universal Serial Bus (USB 2.0). The USB-1149.1/E is a high-speed
device compliant with Revision 2.0 of the USB Bus Specification
(backward compatible with the full-speed features of Revision 1.1).
The voltage level of the parallel I/O and the TAP interface is
software programmable and can be set to any voltage between 1.25V
and 3.3V in increments of 0.05V. The USB-1149.1/E TCK output to the
IEEE Standard 1149.1 compatible target system is programmable under
software control and supports speeds of up to 100MHz.

Controller Specifications
Programmable Clock
The system-wide TCK rate for all TAP ports is
programmable under software control. A wide range of TCK
frequencies can be achieved by using the on-board
Phase-Locked-Loop (PLL) generation circuitry. Depending
on the controller, users are given the ability to select
the desired TCK rate from a range of values up to 100
MHz at resolution increments of less than 2%.
Adjustable Low Voltage Outputs
The voltage level of the parallel I/O, the local TAP
port, and each pod TAP is software programmable and can
be set to any voltage between 1.25V and 3.3V in increments of 0.05V. The ports of the
ScanTAP-4, ScanTAP-8, and ScanTAP-32 pods can also be
slew rate (fast/slow) adjusted.
Scan Input Signal Delay Compensation
Automatic delay compensation is inserted within the
signal paths. This feature solves the well-known
problems associated with the combination of high TCK
rates and remote target locations at extended distances.
Target Voltage Detection System
The controller and its remote pod include
analog-to-digital converters, which can measure
connected power voltages from the target. Such voltages
from two distinct target levels can be measured and
compared against user-defined limits. This feature can
provide detailed signal voltage checks at any stage of a
test plan.
Automatic Detection of UUT Power Shorts
With the target powered down, a well-regulated drive
current with current limit can be momentarily applied to
the target power bus. By measuring this current, the
approximate load resistance can be calculated. This
provides for the automatic detection of target power
shorts, prior to applying power to the target unit.
