When the tool can detect a gated clock, and the conversion feature is turned on, it will attempt to separate the clock from the rest of the logic in the gate. If it can do so, the clock will directly drive the C pin of the register, and the rest will get assigned to the clock e...
在Vivado中,打开综合后的设计,可通过report_clock_networks显示所有时钟,包括门控时钟。如下图所示,分别显示了-gated_clock_conversion为on和off时Vivado检测到的时钟,可验证-gated_clock_conversion所起的作用。 结论 -门控时钟会给设计带来一些负面影响,可通过-gated_clock_conversion移除 -当时钟负载少且时钟频率低...
Vivado synthesis allows the conversion of gated clocks. The two items to use to perform this conversion are: A switch (-gated_clock_conversion) in the GUI, that instructs the tool to attempt the conversion. The RTL attribute that instructs the tool about which signal in the gated logic is...
