                        UCF dosyalar\u0131 haz\u0131rlan\u0131rken dikkat edilmesi gereken en \u00f6nemli \u015fey asl\u0131nda LOC \u00f6zelli\u011fidir. LOC bir etiketin hangi i\u011fneye ba\u011flanaca\u011f\u0131n\u0131 belirtir. Mesela LED<7> i\u011fnesi ger\u00e7ekte F9 i\u011fnesine ba\u011fl\u0131 olacakt\u0131r. \u201cLED<7> i\u011fnesi\u201d kullan\u0131m\u0131 burda biraz kafalar\u0131 kar\u0131\u015ft\u0131rabilir. Burada kastedilen LED<7> i\u011fne etiketidir. Yani donan\u0131msal olarak bir i\u011fne temsil etmez. Ama F9 donan\u0131msal bir i\u011fnedir. FPGA entegresinin belirli, g\u00f6r\u00fcnen, \u201cger\u00e7ek\u201d bir i\u011fnesidir. FPGA d\u0131\u015f d\u00fcnya ile bu i\u011fne sayesinde ileti\u015fir.<\/p>\n

                        E\u011fer kulland\u0131\u011f\u0131n\u0131z FPGA geli\u015ftirme kiti veya direk FPGA farkl\u0131 ise yani Spartan S3E Starter Kit de\u011filse LOC de\u011ferinde de\u011fi\u015fiklik yapman\u0131z gerekir. E\u011fer kitiniz Spartan S3E Starter Kit ise yine de dikkat etmeniz gerekir. \u0130nsan hata yapabildi\u011finden UCF dosyas\u0131 kod FPGA kitine yollanmadan bir daha kontrol edilmelidir. Aksi takdir \u00e7\u0131k\u0131\u015f ve giri\u015fler kar\u0131\u015fabilir ve hem FPGA\u2019ya hem de \u00e7evre birimlerine kal\u0131c\u0131 zarar verilebilir.<\/p>\n

                        UCF dosyas\u0131n\u0131 ve atamalar\u0131n\u0131 kontrol etmenin bir yolu UCF dosyas\u0131n\u0131 direk olarak kontrol etmektir. Di\u011fer bir yolu ise Xilinx ISE\u2019nin aray\u00fcz\u00fcnden kod sentezlendikten ve ger\u00e7eklendikte sonra \u201cPinout Report\u201d a bakmakt\u0131r. Programda anl\u0131k bir hata olu\u015fabilece\u011fini ve kod ger\u00e7eklenirken UCF dosyas\u0131n\u0131n yanl\u0131\u015f veya eksik okunabilece\u011fini g\u00f6z \u00f6n\u00fcnde bulundurarak her iki y\u00f6ntem ile kontrol etmek ak\u0131ll\u0131ca olacakt\u0131r. E\u011fer bir etiket i\u00e7in herhangi bir UCF k\u0131s\u0131t\u0131 yok ise o zaman ISE ger\u00e7ekle\u015ftiricisi otomatik olarak bir i\u011fneyi o etikete at\u0131yacakt\u0131r ve bu genelde istedi\u011fimiz i\u011fne olmayacakt\u0131r.<\/p>\n
