What's Good About Allegro Router and Highlighting? You’ll need the SPB16.3 Release to See!

Comments(0)Filed under: PCB design, Allegro PCB Editor, Allegro, via, PCB Editor, PCB, SPB 16.3, layer stacks, Allegro 16.3, layout, "PCB design", SPB16.3, design, routing, Specctra, blind vias, highlighting, buried vias

Just a quick post this week on a new Allegro PCB Router feature in the SPB16.3 release. A small feature, but very useful!

Highlight/Unhighlight bbvias


The following command is accessible in SPB16.3 SPECCTRA to highlight/unhighlight selected kinds of blind and buried vias (bbvias):

        highlight <object_type> [<start_layer> [<finish_layer>]] on|off

object_type::= bbvias | blind_vias | buried_vias

start_layer valid layer name where bbvia starts from

finish_layer valid layer name where bbvia ends

 

Notes: bbvias – blind and buried vias are highlighted (unhighlighted)

blind_vias - only blind vias are highlighted (unhighlighted)

buried_vias - only buried vias are highlighted (unhighlighted)



If layers aren’t specified bbvias from all layers are highlighted or unhighlighted

If only one layer is specified only crossing this layer bbvias are highlighted (unhighlighted)
on – highlight objects
off – unhighlight objects




Here’s an example:

Command > highlight bbvias on

will highlight all bbvias
 

Please share your experience using this new SPB16.3 capability.
