Figure 7. JTAG Clocktree for Multiple ADSP-2106x Systems
Connecting CLKIN to Pin 4 of the EZ-ICE
header is optional.
The emulator only uses CLKIN when directed to perform
operations such as starting, stopping and single-stepping mul-
tiple ADSP-21061 in a
synchronous
manner. If you do not need
these operations to occur synchronously on the multiple proces-
sors, simply tie Pin 4 of the EZ-ICE
header to ground.
If synchronous multiprocessor operations are needed and
CLKIN is connected, clock skew between the multiple ADSP-
21061/ADSP-21061L processors and the CLKIN pin on the
EZ-ICE
header
must be minimal
. If the skew is too large, syn-
chronous operations may be off by one or more cycles between
processors. For synchronous multiprocessor operation TCK,
TMS, CLKIN and
EMU
should be treated as critical signals in
terms of skew, and should be laid out as short as possible on
your board. If TCK, TMS and CLKIN are driving a large num-
ber of ADSP-21061 (more than eight) in your system, then
treat them as a clock tree using multiple drivers to minimize
skew. (See Figure 7, JTAG Clock Tree, and Clock Distribution
in the High Frequency Design Considerations section of the
ADSP-2106x User’s Manual, Second Edition
.)
If synchronous multiprocessor operations are not needed (i.e.,
CLKIN is not connected), just use appropriate parallel termina-
tion on TCK and TMS. TDI, TDO,
EMU
and
TRST
are not
critical signals in terms of skew.
