axlDBCreateVia

archive

Hello all.

I have a lot of unconnected vias. they have no connect line, they are only vias to interconnect negatives shapes together through the cross section.
I want them to be connected to a net. By hand, I have to connect from something (a shape for example) and then put the connection to the via.

I wrote a little routine to this.
I cannot use the axlChangeNet (not allowed for vias).
So i use a workaround:
I extract via xy and name and then use axlDBCreateVia to create a new one at the same point, with the same name but another net.
It works perfectly. all my vias are finally connected. I save the BRD file, reopen it. They are still connected to what I wanted..
But, after some commands in Allegro, they came back to unconnected vias!
I tried to add a axlDBRefreshId on new vias (not really necessary, they are new ;-), run a dbdoctor on the BRD, not better!

Whatever I did, they finish to be unconnected.

Any ideas to fix it?

Thanks in advance.

  • try this approach:
    1) extract the via's name and xy, ...
    2)use cloak to speed up Skill
    3) delete the VIA
    4) place a new via with a net name of your choice
    5) goto 3 for next via
    6) close the cloak

    axlDBCreateVia(
    t_padstack
    l_anchorPoint
    [t_netName]
    [g_mirror]
    [f_rotation]
