亲爱的朋友，我用的是Sparten 6 LX75T。根据xilinx的PCB设计和PIN规划指南文件，他们提到VCC INT的电容器和所有其他电源的电压都非常低。我正在研究ALTERA产品，我通过PDN工具计算了许多用于相同电流和电源和逻辑的耦合电容器。那么为什么Xilix FPGA Sparten 6需要的耦合电容更少？亲切的问候，Sameer以上来自于谷歌翻译以下为原文Dear Friend, I use Sparten 6 LX75T. According to PCB design and PIN planning guide document by xilinx, They mentioned very less capacitor for VCC INT and all othersupply volatage . I was working on ALTERA product befor , i calculatedmany Coupling capacitors by PDN tool for same current and supply and logic. So Why do Xilix FPGA Sparten 6 need very less coupling capacitor ?Kind Regards,Sameer

大家好！我在电路板上的第一条消息......我的问题：当使用Impact 11.4和Platform cable USB II对我的xc3s250e进行编程时，它有时会在编程后变得非常热。没有燃烧，不能用手指触摸它。关闭和打开fpga板并再次尝试没有帮助，同样的事情，在编程时会变热。解决此问题的方法是重新启动IMPACT。然后它将正常编程。使用相同的位文件。这个问题大约在100个编程中发生。当影响持续整整一个工作日时，太过分了。因此，这使我得出结论，这是一个影响问题。我真的想通知xilinx这个问题。还有其他人经历过这个吗？BR，艾瑞克琳达尔Actiwave AB瑞典以上来自于谷歌翻译以下为原文Hi all! my first message on the board.. My problem: When programming my xc3s250e using impact 11.4 and Platform cable USB II it sometimes after programming gets extremely hot. Cannot touch it with my fingers without burning. Powering off and on the fpga-board and trying again doesnt help, same thing, gets hot when programmed. The solution to this problem is to restart IMPACT. Then it will program as normal. Using the same bit file. This problem happens about 1 in 100 programming. Offenly when impact has been running for a whole working day. So, this leads me to the conclusion that this is an impact issue. I would really like to inform xilinx about this issue.Anyone else who have experienced this? BR,Erik LindahlActiwave ABSweden
