ACEX 1K Programmable Logic Device Family Data Sheet
IEEE Std.
1149.1 (JTAG)
Boundary-Scan
Support
All ACEX 1K devices provide JTAG BST circuitry that complies with the
IEEE Std. 1149.1-1990 specification. ACEX 1K devices can also be
configured using the JTAG pins through the ByteBlasterMV or BitBlaster
download cable, or via hardware that uses the JamTM Standard Test and
Programming Language (STAPL), JEDEC standard JESD-71. JTAG
boundary-scan testing can be performed before or after configuration, but
not during configuration. ACEX 1K devices support the JTAG
instructions shown in Table 14.
The instruction register length of ACEX 1K devices is 10 bits. The
USERCODE register length in ACEX 1K devices is 32 bits; 7 bits are
show the boundary-scan register length and device IDCODE information
for ACEX 1K devices.
Table 14. ACEX 1K JTAG Instructions
JTAG Instruction
Description
SAMPLE/PRELOAD
Allows a snapshot of signals at the device pins to be captured and examined during
normal device operation and permits an initial data pattern to be output at the device
pins.
EXTEST
Allows the external circuitry and board-level interconnections to be tested by forcing a
test pattern at the output pins and capturing test results at the input pins.
BYPASS
Places the 1-bit bypass register between the TDI and TDO pins, allowing the BST data
to pass synchronously through a selected device to adjacent devices during normal
operation.
USERCODE
Selects the user electronic signature (USERCODE) register and places it between the
TDI
and TDO pins, allowing the USERCODE to be serially shifted out of TDO.
IDCODE
Selects the IDCODE register and places it between TDI and TDO, allowing the IDCODE
to be serially shifted out of TDO.
ICR Instructions
These instructions are used when configuring an ACEX 1K device via JTAG ports using
a MasterBlaster, ByteBlasterMV, or BitBlaster download cable, or a Jam File (.jam) or
Jam Byte-Code File (.jbc) via an embedded processor.
