If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)

x      (a) The reasons described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense;
  (b) The subject annual report, semi-annual report, transition report on Form 10-K, Form 20-F, Form 11-K, Form N-SAR or Form N-CSR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q or subject distribution report on Form 10-D, or portion thereof, will be filed on or before the fifth calendar day following the prescribed due date; and
  (c)       The accountant’s statement or other exhibit required by Rule 12b-25(c) has been attached if applicable.


State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

On May 27, 2009, Xilinx, Inc. (the "Company") received an adverse judicial ruling regarding a previously-disclosed dispute with the Internal Revenue Service concerning the Company's cost sharing agreement with Xilinx Ireland. Because the Annual Report on Form 10-K to which this Form 12b-25 relates was also due on May 27, 2009, the Company must delay the filing of that Form 10-K in order to consider the impact of that ruling on the disclosure in such Form 10-K.
