Bitstream Generation Implementation Options
Option
TCL Option
Description
Serial Flash (
.flash
)
bitstream output flash
This option enables the generation of
an additional Serial Flash formatted
output file. This file will be named
the same as the STAPL file, but with
a
.flash
extension.
4x Serial Flash
(
.flash4x 0-3
)
bitstream output 4xflash
This option enables the generation of
four additional 4x Serial Flash
formatted output files. These files
will be named the same as the
STAPL file, but with a
.flash4x 0
to
.flash4x 3
extension.
CPU Mode (.cpu)
bitstream output cpu
This option enables the generation of
an additional CPU Mode formatted
output file. This file will be named
the same as the STAPL file, but with
a
.cpu
extension.
Raw Hex (.hex)
bitstream output hex
This option enables the generation of
an additional Raw Hex formatted
output file. This file will be named
the same as the STAPL file, but with
a
.hex
extension.
Single Device Chain
bitstream single device
This option specifies whether the
bitstream STAPL file will be output
for a single-device JTAG scan chain
(the target device is the only device
on the JTAG scan chain). Set this to 1
to indicate a single device. If this
option is set to 0 (indicating multiple
devices in the scan chain), then
either the a chain description file
will be used or the pre-IR, post-IR,
and chain offset options will be used
to generate the bitstream STAPL file
with knowledge of the scan chain.
Use JESD32 Chain
Description File
bitstream use chain file
When using a multi-device JTAG
scan chain, specifies whether to use
a JESD32 chain description file, or to
use the explicit pre-IR, post-IR, and
chain offset implementation options.
Chain Description File
bitstream chain file
This option specifies the optional
JESD32 chain description file used
by the bitstream generator to
automatically pad the JTAG IR chain
for multi-device chains.
