was connected to VCCO(3.3V) instead of Vccaux(2.5V) mistakenly, so does this mistake cause any harm to FPGA

unnamed or undefined and they then get turned on when you defined them elsewhere...Is there any harm

IOA.1SYNCDELAY; CLR IOA.3SYNCDELAY;I know, syncdelay is not really required here, but it should not do any harm

大家好，我们计划将LVDS_25与Artix-7（XC7A200T-2FBG484I）配合使用。 Artix将LVDS_25发送到ASIC，驱动器不得超过1.6V。将LVDS_25驱动到ASIC是否安全？输出Vcm是否有机会超过安全边际？先谢谢你，帕诺斯以上来自于谷歌翻译以下为原文Hello all, we are planning to use LVDS_25 with a Artix-7 (XC7A200T-2FBG484I). The Artix sends LVDS_25 to an ASIC which drivers must not exceed 1.6V. Is it safe to drive LVDS_25 to the ASIC? Is there any opportunity for the output Vcm to exceed the safe margin? Thank you in advance, Panos

在安装PSoC Creator、PSoC设计器或PSoC程序员时，可能会出现此问题。当CyInstaller回滚而不显示任何错误消息时，按照以下步骤查找根本原因：1）首先，进入Windows中的“事件查看器”转到“控制面板”选择“管理工具”打开“事件查看器”2）在右窗格上，单击Windows，并选择应用程序3）搜索有关CySturver的信息，并检查详细信息选项卡中安装程序的突然回滚的原因。4）如果错误是因为某些字体不可用，如Arial，则在字体部分中的Windows控制面板中复制ARIAL字体或Internet中的特定字体。5）现在重新开始安装。 以上来自于百度翻译 以下为原文This problem can occur while installing PSoC Creator, PSoC Designer or PSoC Programmer. When CyInstaller rollback without showing any error message, follow these steps to find the root cause:- 1) First of all, go to “Event Viewer” in Windows a. Go to “Control Panel” b. Select “Administrative Tools” c. Open “Event Viewer” 2) On the right pane, click on Windows, and select Application 3) Search for the Information about CyInstaller and check the reason for abrupt rollback of Installer available in Details tab. 4) If error is because of unavailability of some font like Arial, than copy the Arial font or that particular font from internet in your Windows Control panel in Font section. 5) Now start the installation again.

由于军队电子化程度的迅速提高，电子战被作为直接用于攻防的作战手段，形成了“陆、海、空、天、电”多维立体战。未来的高技术战争，电子战将发挥巨大作用，没有制电磁权就谈不上“制天、制空、制海、制陆”权。那么，这么“高大上”的电子战到底是什么呢？

当未使用的输出在约束文件中注释掉并且显然未在项目中声明时，fpga板上的输出引脚状态是什么 - 特别是对于Vivado 14.4 Verilog。在一些示例中，未使用的输出端口在约束文件中明确声明，然后明确地设置为低功率状态（取决于功能的高或低）。谢谢以上来自于谷歌翻译以下为原文What is the state of output pins on a fpga boardwhen the unused outputs are commented out in constraint file and obviously not declared in the project - specifically for Vivado 14.4 Verilog. In some examples, the unused output ports are explictly declared in the constrainst file and then explictly set to a low power state (high or low depending on the function). Thanks
