3.3.3. 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.
