在边界扫描模式下(Boundary-Scan Mode),ISE的iMPACT是如何把后缀为.bit的配置信息传输到FPGA器件中呢? 先引用两段ISE Help中相关概念的描述,让大家对bitstream和.bit这两个基本概念理解得更透彻一些。bitstreamA bitstream is a stream of data that contains location information for logic on a device, that is, the placement of configurable logic blocks (CLBs), input/output blocks (IOBs), tristate buffers (TBUFs), pins, and routing elements. The bitstream also includes empty placeholders that are filled with the logical states sent by the device during a readback. Only the memory elements, such as flip-f…
