DC综合时出现 1 high-fanout nets

时间:10-02 整理:3721RD 点击:
做DC综合时出现 1 high-fanout nets,如下:
Warning: Design 'VR_CS_TOP' contains 1 high-fanout nets. A fanout number of 1000 will be used for delay calculations involving these nets. (TIM-134)
Net 'uVR_CS_DITHER/rstb': 1074 load(s), 1 driver(s)
"rstb"是复位信号,脚本设置如下:
create_clock -name pclk -period 30 -waveform [list 0 15] [get_ports pclk]
set_dont_touch_network [list pclk]

set_ideal_network -no_propagaterstb
set_disable_timing [get_ports rstb]
求高手赐教,谢谢!

自顶,在线等
