Express Mode uses an 8-bit wide bus path for fast configuration of Xilinx FPGAs. Thisapplication note provides information on how to perform Express configuration specifically forthe Spartan™-XL family. The Express mode signals and their associated timing are defined.The steps of Express configuration are described in detail, followed by detailed instructions thatshow how to implement the configuration circui
PCI總線是目前最為流行的一種局部性總線 通過對PCI總線一些典型功能的分析以及時序的闡述，利用VetilogHDL設計了一個將非PCI功能設備轉接到PC1總線上的IP Core 同時，通過在ModeISim SE PLUS 6．0
上運行測試程序模塊，得到了理想的仿真數據波形，從軟件上證明了功能的實現。
