Yes you can
Take the TDO of the first CPLD into the TDI of the
second and TDO of the last CPLD back into the
TDO of the programming
cable.
Also connect TMS,TCK (and nTRST if it is used) in
parallel to both CPLDs.
If you uses WebPack the iMPACT programmer will
automatically detect the devices in the JTAG chain upon
initialization and you can program them by assigning the appropriate .bit
files.

Subject: [oc] AVNET XPA3 CPLD Board
Hello
I have one AVNET XPA3 CPLD board with JTAG IN port and a coolrunner xpa 3
cpld that is soldered on the board, is it possible for me to place another
cpld in parallel to the board cpld with connections from board CPLD JTAG pins
to other CPLD JTAG pins and programmed both CPLDs.
Thanks
