3.4.3. JTAG Multi-Device Configuration
You can configure multiple devices in a JTAG chain. Observe the following pin connections and guidelines for this configuration
setup:
•
One JTAG-compatible header connects to several devices in a JTAG chain. The drive capability of the download cable is the
only limit on the number of devices in the JTAG chain.
•
If you have four or more devices in a JTAG chain, buffer the
TCK
,
TDI
, and
TMS
pins with an on-board buffer. You can also
connect other Intel FPGA devices with JTAG support to the chain.
