[PCB_FORUM] Re: Auto Router Via Grid

I am making the assumption that you are fanning out for 
ICT test.  I don't know if there is a way to set a via versus routing grid in 
allego
but I can offer some help.


Here are two suggestions:
The visual method involve a common setup is 25 and 5 

This is done by going to Setup=> Grid entering 25 in the x & y for Non Etch
Then enter 5 5 5 5 5 in the x & y for All Etch. You can then manually place 
your vias durring fanout
every other highlighted grid. 

Another method is setting this under fanout by pick. 

Choose Route=>Fanout By Pick then click your right mouse button and choose 
setup.  There
is a Testpoint Tab in this dialog box that allows you to set the via grid.

Subject: [PCB_FORUM] Auto Router Via Grid


I look thru the documentation before posting here.  I am fairly new  to Cadence 
tool suite.

I see how  to set the Via grid in the Shape based Auto Router but I do not see 
a Via Grid in the native Allegro tool itself.  How does one control, in Allegro 
etch editor, moving vias on 50 mil grid while moving clines on a 5 mil grid?  
Any help would be appreciated.  Thank You.
