using generic flash IP and this time problem is not related to quartus software.

FPGA AS configuration is delaying when board temperature is high.

till 30deg no delay observed in AS configuration but after 30deg FPGA AS configuration delay is increasing with temperature.

what might be reason behind this temperature dependency.

producing thousands of boards and only in one board this problem is detected.

no problem with circuit, no problem with power levels.
