怎么使用ISE Webpack生成比特流

我们正在开发一个与几个带有Spartan 6的ADC一起使用的板。我们决定使用SPI闪存并使用主SPI编程模式。
既然我们以前从未这样做过（我们一直在使用Xilinx闪存），我想知道ifourunderstanding不正确，并希望得到任何帮助和建议：
1.我们将使用ISE Webpack生成比特流。
2.然后我们将生成一个新文件，由SPI闪存使用，包含上一步中获得的比特流。
3.现在我们将使用iMPACT工具向Spartan 6下载“SPI Flash编程”比特流，该工具将从PC接收数据，以便使用步骤2中生成的文件对SPI进行编程。
4.我们将使用PROG_B使用SPI中的新数据重启Spartan 6。
做完了!!
我们从目前为止阅读的文档中了解到这一点。
提前致谢！！



以下为原文

We are developing a board for use with several ADCs with a Spartan 6. We've decided to use a SPI Flash memory and use the Master SPI programming mode.
Since we've never done this before (we've been using Xilinx Flash memories), I'd like to know if our understanding is correct and would appreciate any help and suggestions:
1. We'll generate the bitstream using the ISE Webpack.
2. Then we'll generate a new file, to be used by the SPI Flash memory, containing the bitstream obtained in the previous step.
3. Now we'll download to the Spartan 6 a "SPI Flash programming" bitstream, using the iMPACT tool, which will receive the data from the PC in order to program the SPI using the file generated in step 2.
4. We'll use PROG_B to reboot the Spartan 6 using the new data from the SPI.
5. Done!!

We understand this from the documentation read so far.

Thanks in advance!!
