I have a strange problem:
1) without programing fpga , impact id code loop without any error for 10000 tims;
2) after programing fpga, impact id code looop will have random error
3) after I burn out all chip except fpga itself, just the same as before.
4) I use xc3s250epq208
some one can help me ?

Check the power supply load capabilities. Check the voltages after programming the FPGA. The voltages should be as per data sheet recommendations.
