spartenxc3s50an deovice id does not match

we design a board on which a spartenxc3s50an

and that deovice is not find that deovice id does not match

error as follows

1). INFO:iMPACT:583 - '1': The idcode read from the device does not match the idcode in the bsdl File.
INFO:iMPACT:1578 - '1':  Device IDCODE :        00000000000000000000000000000000
INFO:iMPACT:1579 - '1': Expected IDCODE:    00000010011000010000000010010011

2).ERROR:iMPACT:585 - A problem may exist in the hardware configuration. Check that the cable, scan chain, and power connections are intact, that the specified scan chain configuration matches the actual hardware, and that the power supply is adequate and delivering the correct voltage. PROGRESS_END - End Operation. Elapsed time = 0 sec.

Re: spartenxc3s50an deovice id does not match

Since the ID code is all zeroes, it looks like your scan chain is broken.  Check that the part has all of the

required power supplies.  A missing core logic supply or VccAux could cause this.  Also make sure all of your

JTAG signals are connected correctly.  Missing connections to TDI, TMS or TCK can also cause this sort

of symptom.

Re: spartenxc3s50an deovice id does not match

  • In most cases, this IDCODE error message is indicative of a board problem. Mostly problems related to JTAG chain hardware. So please check all the programming hardware of the board.
  • Perform an IDCODE looping test. If IDCODE looping fails, see http://www.xilinx.com/support/answers/8902.htm

 

  • Check all the connections as per configuration guide recommendations

 

  • Check the continuity of the cable & cable insertion direction.

 

  • Check all the voltages of device. They should be with the range  as per data sheet recommendations
