ICC 布线时via数量,可否控制为single_via

.8工艺！
默认是不加的吧
你报一下你现在绕线的option都是啥，看是否有必要再设置一下

Default routing via是一顆,你應該有下到redundant_via設定

>report_route_option
Current routing options:
Time driven = 0
Timing wt = 4
Skew control = 0
Congestion wt = 4
Incremental = 0
Incremental = 0
Clock routing = balanced
Track Assignment options:
Timing driven = 0
Timing wt = 1
Detail route options:
Connect tie off = 1
Connect open = 1
Reroute user wire = 0
CTS nets = minor change only
Single row/col via array = center
Stack via less min area = add metal stub
Stack via less min area cost = 0
Library options:
Poly pin access = auto
DRC distance = diagonal
Same net notch = ignore
Fat wire check = merge then check
Fat wire merge = preroute and signal
Treat fat blockage as = fat wire
wire contact end-of-line = ignore

MS 将set_route_zrt_common_options 中的post_detail_route_redundant_via_insertion设成off就可以了

另, 三楼的report命令应该用report_route_zrt_common_options才对,
因为是在Zroute模式下.
