Hello ,
On A10SOC KIT board, I compile PCIe_gen3x8-Avmm design example, but Time Report show below critical warning ?
I wanto understand what‘s this Critical Warning meaning’ is ?
Does it mean the worst value of "Setup Time" ,between "altera_reserved_tck" to "pcie_a10_hip_0|~CORE_CLK_OUT" is "-0.002", and this negative -0.002 is not allowed. right ?
How to fix it ? Thanks a lot

Yes, it should not be allowed. This happened usually you use a different version of Quartus Prime.
This clock used for signal tap. What you can try is use different seeds to close the timing since the value is small.
