altera_reserved_tck hold timing violation

In the help document:

https://www.intel.com/content/www/us/en/programmable/support/support-resources/knowledge-base/solutions/rd10082012_359.html

it is mentioned to set altera_reserved_tck on global signal to avoid hold time violation,

but doing this give this error on quartus 19.3 arria 10:

    Hi,

    This error is not related to the Global Clock assignment. The error indicates that the source that feeds the specified port in the specified JTAG block is not a pin. You have to modify the design so that the source of the port is a pin.

    Thanks.

      Hi YY,

      This error only occurs when I add the QSF line for global clock:

      set_instance_assignment -name GLOBAL_SIGNAL GLOBAL_CLOCK -to altera_reserved_tck -entity Achilles_arria_X

      Nothing else has changed in RTL.

      Removing the line solves the issue.

      Could you take one of your arria 10 test case and add that line in the qsf?

      set_instance_assignment -name GLOBAL_SIGNAL GLOBAL_CLOCK -to altera_reserved_tck

    Hi,

    Every design has its own assignments/settings that contribute to different compilation result. It would be great if you could provide the design. It doesnt need to be the full design, a simple testcase would be helpful.

    Thanks.

    Hi, Quartus 19.4 has solved the issue, I do not need to assign any altera_* constraints anymore.

    Ticket can be closed.
