你好，我试图通过修改自动生成的MIG XDC来制作XDC。但是当我使用如下所示的set_property时，Vivado找不到具有该过滤器的单元格。pcu是top模块下的一个intance。从pcu

嗨，我正在处理系统，当几个单独的应用程序运行在PIC18上。我需要验证Flash在哪个区域执行代码。因此，我的想法是准备PC（程序计数器）的当前值。您知道如何用C语言来实现吗？在PIC32上可以使用宏_CP0_GET_EPC()。对于PIC18I使用XC8编译器，我无法找到类似的解决方案。

我正在使用SPC560D和SPC5Studio。我想在将设备置于待机模式之前保存设备配置/状态，并在设备退出待机模式时使用/检索此状态。这可以通过使用SRAM来实现吗？如何访问SRAM以进行可变存储？ 任何使用SRAM的例子都会有所帮助。谢谢。麦克风。以上来自于谷歌翻译以下为原文 I am using SPC560D with SPC5Studio. I want to save the device configuration/status before putting the device to standby mode and use/retrieve this status when the device exits standby mode. Can this be achieved by using SRAM? How to access SRAM for variable storage? Any example for using SRAM will be helpful. Thanks. Mike.

And suspect that it is the ISE software that need some aditional driver information my xilinx install path is /opt/Xilinx/14.6/ISE_DS/ hope this information is of any help for you to help me and if you need aditional info just ask and I'll try to provide it - thanks in advance //Applop
