关键问题
针对 Arria V 设备家族以及该产品家族的设计 包含 10GBASE-R PHY v12.0 宏功能,如果您运行设计 安装助手后,Design Assistant 将生成以下内容 四个关键警告:
Critical Warning (332012): Synopsys Design Constraints File file not found
Critical Warning (308019): (Critical) Rule C101: Gated clock should be implemented according to the Altera standard scheme
Critical Warning (308060): (High) Rule D101: Data bits are not synchronized when transferred between asynchronous clock domains
Critical Warning (308067): (High) Rule D103: Data bits are not correctly synchronized when transferred between asynchronous clock domains
这些警告与 Quartus 时序分析有关 II 软件版本 12.0 不支持 Arria V 设备。
如要进行编译和功能模拟,您可以安全地 忽略这些警告。
