在这个修改后的例子中,我们将组合逻辑转换为了时序逻辑,使用时钟边沿来触发信号更新,从而打破了Timing Loop。 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。

More information on the Analysis Perspective can be found in the Design Analysis section of the Vivado Design Suite Tutorial: High- Level Synthesis (UG871). TIP: Remember, even if a Tcl flow is used to create designs, the project can still be opened in the GUI and the Analysis Perspective...
Updated timing constraints so Vivado now applies them correctly to all instances of the Zmod Digitizer IP present in the block design, not just the first one encountered. lianjwen-li authored and artvvb committedDec 14, 2023 87e41b7

All Versal® ACAP design process Design Hubs and the Design Flow Assistant materials can be found on the Xilinx.com website. This document covers the following design processes: • Hardware, IP, and Platform Development: Creating the PL IP blocks for the hardware platform, creating PL ...
2 LUT cells form a combinatorial loop. This can create a race condition. Timing analysis may not be accurate. The preferred resolution is to modify the design to remove combinatorial logic loops. To allow bitstream creation for designs with combinatorial logic loops (not recommended), use this ...
