Adam, http://support.xilinx.com/xlnx/xweb/xil_tx_display.jsp?sGlobalNavPick=&sSecondaryNavPick=&category=&iLanguageID=1&multPartNum=1&sTechX_ID=al_power details what we used to do, vs. what we do now. Also look in section 3 of any datasheet for the Iccint, Iccaux, and Icco current requirements. As of V2, we require that the current provided be at least the quiescent current needed, and no more than that.

Is your design a lot smaller than the smallest S3 part, the XC3S50? If so, then I guess a newer part won't do you any good. -- Rick "rickman" Collins rick.collins@XYarius.com Ignore the reply address. To email me use the above address with the XY removed.
