Hi Ted,
When we debug your design with the JTAG interface, the JTAG signals TCK, TMS, TDI, and TDO are implemented as part of the design.
The altera_reserved_tck/tms/tdi pin is automatically generated for a design that uses a JTAG accessible module such as the Nios II debugger, SignalTap II logic analyzer, and In-System Memory Content Editor.
For timing constraint those pins
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}
