In Allegro 15.2 I had this test thru via V30C16D.I would like to use this same via as a test point in 15.5.1 but I don't know how to set it up.Can someone help me with this?Thanks,Mihai
I have made this change.But when I try to go Testprep manual -> Add I get this message.E- Can't create probe: Pad Too Small
Check your "Min pad size" in the "General Parameters" tab.
I have changed the min pad size to 0.0 just like in 15.2.When I try to manually add a test point now it creates a test point, but does not replace the via with the right via that I assigned in the Tesprep Param->Padstack Selections.
At the bottom of the Padstack Selections tab, click on the "Load new existing vias" button. If you get multiple lines that you don't need, right-click on the line and select "Delete". Then check the "Replace vias" box, then enter the "BOTTOM Side Replacement", then check the "Enable" box.
Your suggestions worked up till "Enable".It will not let me enable the new via, and every time I get to the padstack selection window the bottom window is always empty.
You can't "Enable" until you fill in the "Bottom Side Replacement". Also, the existing via should be what you're using as non-testpoint vias and the Bottom Side Replacement should be your testpoint via (two different padstacks). Therefore, your row in the bottom section will have two different padstacks listed.
Randy,You're a genious man.I finally got this stupid tespoint add going. It seemed so easy in 15.2 and so complicated in 15.5.1.Thank you again.Mihai
