1.安裝Vivado 2017.4后，打開軟件出現(xiàn)如下圖“應用程序無法正常啟動（0xc000007b）”錯誤：

原因：缺少Microsoft Visual C++ Redistributable 系統(tǒng)運行庫導致。

措施：安裝vc_redist.x64.exe運行庫，下載地址：https://aka.ms/vs/17/release/vc_redist.x64.exe。

3. Vivado 未使用的管腳如何約束？

A：在.xdc文件中增加以下之一約束：

//方法1：set_property SEVERITY {Warning} [get_drc_checks NSTD-1]set_property SEVERITY {Warning} [get_drc_checks RTSTAT-1]set_property SEVERITY {Warning} [get_drc_checks UCIO-1]
//方法2：set_property BITSTREAM.CONFIG.UNUSEDPIN Pulldown [current_design]set_property BITSTREAM.CONFIG.UNUSEDPIN Pullup [current_design]set_property BITSTREAM.CONFIG.UNUSEDPIN Pullnone [current_design]

2. Vivado軟件支持的第三方仿真軟件版本對應關(guān)系
