strange idcode loop error with IMPACT

  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 ?

Re: strange idcode loop error with IMPACT

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