Description
Allows off-chip circuitry and interconnect to be tested.
Allows snapshot of normal operation. Also allows data to be
loaded on parallel output boundary scan registers.
Places device in bypass mode so that there is single shift register
stage between TDI and TDO.
Allows scanning of the device identification register.
Tristates all output drivers with the exception of TDO.
Allows the state of the signals driven from component pins to be
determined from the boundary-scan register while the BYPASS
register is selected as the serial path between TDI and TDO.
Enables on chip BIST logic to perform memory BIST.
Allows the assertion of internal test_mode signal to prevent the
asynchronous resets from inadvertantly resetting the flip-flops
during internal scan.

BIST SUPPORT
The memory BIST can be initiated through JTAG interface
using the RUNBIST instruction or by setting the Onboard
Memory BIST bit in the Start register. When the memory
BIST is initiated through the JTAG interface the result of
pass/fail will be set in the Memory BIST Result bit in the
Status register and also in the BIST status register that can
be accessed through the JTAG interface. The BIST status
register is a one bit register and is connected in the serial
path of TDO and TDI when RUNBIST instruction is scanned
into the instruction register. Once the BIST is done the
contents of the BIST status register can be scanned out to
determine whether the memory BIST passed or failed. If the
memory BIST is initiated through the Onboard Memory BIST
bit in the Start register the result of pass/fail will be set only
in the BIST Result bit in the status register. The memory
BIST will initialize the memory to zero.
SCAN METHODOLOGy
The STA101 supports internal scan through the shared ports
SCAN_EN, SCAN_IN, SCAN_OUT. Before initiating an in-
ternal scan test the user should scan in SCANTEST instruc-
tion through the JTAG interface so that an internal test-
_mode signal can be asserted. This test_mode signal is
used to prevent the reset from inadvertantly resetting the
flip-flops during internal scan. The test vectors to verify the
scan chain are generated by the Sunrise test tool. The target
for the stuck-at fault coverage is 97% and the achieved fault
coverage is about 99%.
