請問如何用skill統計unconnect數目?

Skill > miss=length(setof(net axlDBGetDesign()->nets net->unconnected>0))
1

但是net被設為NO_RAT 就會不統計該條net 尚未拉完線
Net: SOCNDTRA_R has been selected.
Property NO_RAT added to 1 element(s).

Skill > miss=length(setof(net axlDBGetDesign()->nets net->unconnected>0))
0

目前是暫用 report sum.rpt 然後讀sum.rpt 的Missing Connections

謝謝

昨日上 candence 網站去請教已解決:

To check a complete design check for all net->branches with more than 2 entries.

So something like this:

miss=length(setof(net axlDBGetDesign()->nets cadr(net->branches)))

A branch is:

Is the set of all the etch objects—ppins, etch paths, shapes, and vias—associated with a particular signal name. Every net has a name which is its signal name. A net contains one or
more branches. Each branch is a list of the etch objects that are physically connected among themselves. A branch can include ppins, etch paths, shapes, and vias. The number of branches in
a net varies as Allegro PCB Editor connects or disconnects parts of the net. A completely connected net consists of one and only one branch.
