How to do with unconstrained paths which is introduced by the JTAG and GSFI IP?

hi,

My platform: 10AS016E4F29E3SG with Quartus prime pro V22.4

I realized a HPS system in my design and I use a GSFI IP to control the QSPI flash.

both the logic and the HPS work well but there are unconstrained paths reported after full complilation as below image shows.

I checked the 3 clocks with red highlighted, the 1st is JTAG clock and the 2nd and 3 rd are both introduced by the GSGI IP.

so my question:

I have thought for these clocks the tool will add constraints automaticlly as the EMIF IP do, but it seems not, how to add constraints for them?

let me know if you need more information.

thank you and best regards,

rain,
