xilinx Z7 (7Z045) control chip warms up quickly at boot time

1, xilinx Z7 (7Z045) PS side mounted DDR, Z7 and DDR die is sealed together as system in package, now the low temperature -40 °, PS side mounted DDR initialization error, rise to -20 can be initialized, currently want to let the chip in the BOOT to let the chip heat up the temperature of the DDR, let the chip in the boot heat up, while the boot constantly detect the temperature of the internal temperature diode, rise to a certain temperature before initializing the DDR. boot constantly detect the temperature of the internal temperature diode temperature, rise to a certain temperature before the initialization of the DDR, please advise whether this method is feasible, whether at the same time so that the PL side can load the configuration or constraints after the special bit file, so that the FPGA is also hot, I feel that it is necessary to use all the resources than the normal run full performance is still hot, similar to the kind of internal error heating!
2、How to let zynq PL load bit file without PS
