The altera_reserved_tck pin is automatically generated for a design that uses a JTAG accessible module such as the SignalTap II logic analyzer, the In-System Memory Content Editor or the Nios® II debugger.
To constrain this JTAG clock, apply a 33-MHz clock constraint to this pin.
For the TimeQuest Timing Analyzer, use the following command:
create_clock -period "30.303 ns" -name {altera_reserved_tck} {altera_reserved_tck}
Any datapaths crossing into the altera_reserved_tck clock domain from another domain can be set as false paths. Similarly any datapaths crossing from the altera_reserved_tck domain to another domain can also be set as false paths.
