[DRC LUTLP-1] Combinatorial Loop Alert: 1 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. If the loop is known and understood, this DRC can be ...
错误报告:[DRC LUTLP-1] Combinatorial Loop Error Must be Overridden 这个实际上是在Generate Bitstream时出现的问题,不是Implementation问题。 该问题是在赋值过程时出现了类似于assign a = a;的语句,导致某个LUT的输出端口直接接到了输入端口,具体图像忘记截下来了,出问题的代码如下所示,把最后的1去掉就不报错了...
(not recommended), use this command: set_property SEVERITY {Warning} [get_drc_checks LUTLP-1]. NOTE: When using the Vivado Runs infrastructure (e.g. launch_runs Tcl command), add this command to a .tcl file and add that file as a pre-hook for write_bitstream step for the ...
60591 - 2013.4 Vivado Implementation - False LUTLP-1 Critical Warning for path through LUT6_2 Description Vivado DRC reports a false positive for a combinational loop for a path that does loop back to the input of the LUT complex, but to an input pin that is not used by the LUT driving...

使用Vivado生成mcs文件后,将其配置到flash的过程耗时过长。 解决方法: (1)布线完成后,打开Open Implementation (2)在Settings中,点击Bitstream,之后点击Configure additional bitstream settings (3)在Configuration中设置Configuration Rate为33 MHz 之后Ok,退出即可。
In Fig. 1, when the "gate" signal is set to a low condition, the registers are all turned off and are not drawing dynamic power. This type of coding style does not always port well to FPGAs. This is because FPGAs have advanced dedicated clock resources that are designed to set the ...
