EPC16 does not configure EP2C35 at high temperature

Folks, I have been debugging this issue where the EPC16 device I use does not configure the EP2C35 (Cyclone II) device - at slightly high temperature. I can make it configure by cooling down bo...

According to the waveforms, the EPC16 is simply not starting configuration after nSTATUS is deasserted. So I guess, the problem is related to this device rather than the FPGA. The reason for configuration failure can't be explained from the shown waveforms, I think. But it may be probably caused by other EPS16 signals, e. g. an incorrect terminated TCK.
