手动布线模式下时钟网络报Place 30-1880
实现 Place / Route / Opt / Timing 社区未闭环 Versal
一句话结论：疑似时钟树已有布线残留，需清除后再调用update_clock_routing
手动重布时钟网络后运行update_clock_routing报错，网络无法布线
ERROR: [Place 30-1880] my_net_0 cannot be routed with existing routing. The net has a useDistribution only property and the clock source is in row 0 so it can only route to row = 0. This net has a load locked at clock region(2,1) which cannot be routed.
帖中未明确；回答推测与布线数据库中时钟树已有布线有关，需先清除时钟网络布线
