WebOct 3, 2024 · For CT, target_max_fanout can be set with set_ccopt_property command (As @ThisIsNotSam stated). If you set it globally in *.sdc, the most stringent one will be applied during CTS. Moreover, you can set it up differently for top/trunk and leaf nets. Not open for further replies. Similar threads A Web1.1. Advanced I/O Timing Assignments 1.2. Analysis & Synthesis Assignments 1.3.

Max fanout in Vivado -- how does it really work? - Xilinx
Web由此大家可以简单理解为set_max_fanout约束了某条net上驱动的所有cell的个数的总和，而这条net可以由input port驱动， 也可以使内部的任何一条net； 这也是为什么set_max_fanout命令不是用来约束output ports，因为一个输出端口可能会连有很多条net； 而DC是根据net单独进行 ...
