添加约束:在某些情况下,可以通过添加时序约束来引导Vivado的综合和布局布线过程,以避免Timing Loop。 重新进行综合和时序分析: 在修改了设计或添加了约束之后,重新进行综合和时序分析,以验证问题是否得到解决。 使用Vivado的报告功能来检查是否还存在Timing Loop警告。 如果问题仍然存在,考虑在Xilinx的论坛或社区寻求帮助:...

Now that we have identified the RTL file/module, the goal is to find the part of the RTL which is resulting in a crash. This can be due to big loop iterations, long and complex assignment, complex bit slicing, or an incorrect coding style/unsupported constructs. In the above case, the...
You can find detailed information regarding Vivado specific Tcl commands in the Vivado Design Suite Tcl Command Reference Guide (UG835) [Ref 1], or in the help system of the Vivado tools. The Vivado IDE uses Xilinx Design Constraints (XDC) to specify the design constraints. XDC is based on...
