1.Report Clock Networks
report_clock_networks -name {network_1}
2.分析设计中逻辑级数的分布
report_design_analysis -logic_level_distribution -logic_level_dist_paths 5000 -name design_analysis_prePlace
3.筛选"clk"时钟域逻辑级数在[a,b]之间的c条路径
report_timing -name longPaths -of_objects [get_timing_paths -setup -to [get_clocks clk] -max_paths
c -filter {LOGIC_LEVELS>=
a && LOGIC_LEVELS<=
b}]
4.扇出分析 扇出大于a的b条路经
report_high_fanout_nets -fanout_greater_than
a -max_nets
b5. freq & level
125M以下:13级
125-250: 6级
250-350: 5级
350-400: 4级
400以上: 3级
