Test points

archive

Hello,

Does anyone know if Allegro gives a warning when a Testpoint is moved while performing changes to an existing design.

I know that a ""fixed"" property can be attached to test points, however while performing etch changes to an existing design,sometimes the ""fixed"" property needs to be removed,this may cause the unintentional moving of testpoints.


Does anyone have suggestions as to how to handle this, we are trying to avoid having to change test fixtures.

Thanks in advance for you help

Regards

    If the fixed property is applied to the testpoint only and not the cline/net, you should be able to slide the cline without moving the testpoint.

    In the 15.2 release, fix/unfix testpoints has been moved to Manufacture > Testprep. What release are you using? I hope this helps!

    In 15.2, consider running the 'Create Fixture' command prior to the release of your fab package. This creates a new subclass layer, 'fixture_layer' where test locations are represented by circles. When your board is respun, you can overlay your exisiting probe layer (triangles) against the fixture layer (circles) to see if testpoints have been moved. There are no analysis reports at this time to do the compare.

    I'm using both 14.2 and 15 versions.
    Thank you for the response
