Allegro PCB Editor

  • What's Good About Allegro PCB Editor Quickplace Overlap? Check Out 16.6!

    Just a very "quick read" on a new option for Quickplace this week. The Allegro PCB Editor Quickplace is an application used to ‘quickly’ scatter components around the perimeter of the design or to a room location. By default, components are placed not to overlap each other. As a...

  • Missing Drill symbols on the board

    Hello, I have a situation. I have prepared the PCB layout with no issues but the point i stuck on is, i dont see the drill symbols on the prepared board.. e.g I have a through hole pin connectors on my board, i can see the pad stacks, thermal relief and all other things which are there in the footprint...

  • Rel 16.6 - Property exclusion during back-annotation from Allegro to Concept

    We are currently using rel 16.3 and getting ready to transition to rel 16.6. We use both Concept HDL and Allegro. However we create and maintain our constraints in Allegro only. Therefore Concept is not "constraint manager enabled". Starting with rel 16.5, constraint manager is enabled by default...

  • Copper Pouring and Gloss (is it a problem?)

    Hello, i am designing a microcontroller 2 sided board in Allegro 16.5, after routing all the components, i want to apply the Copper Poring(Power Ground) on both sides. I can do it easily but the problem is, after copper pouring when I use "Gloss" option , the blank spaces which was there between...

  • Forcing via connections

    I have a multi-layer design with multiple ground plane layers. But these have issues with ground loops. How can I set something in PCB Editor 16.5 that will only connect vias to one ground plane layer and leave all other layers unconnected, so that I can use a single ground connection point.

  • How to import and export constraints from Allegro PCB to Excel

    We have some complex and large constraints files to use for our designs and it would make life a lot easier if the constraints could be downloaded to excel, modified and then reloaded back into the design. Is there any way that this can be done.

  • DRC T error

    I have a DRC error saying that T's allowed is set to pads and vias only. Where do I change this to allow T's anywhere?

  • What's Good About Allegro PCB Editor Generic Cross-Section Files? See for Yourself in 16.6!

    Beginning with the Allegro PCB Edito r 16.6 release, you are provided a methodology to export a technology (.tcf) or constraints (.dcf) file which is a generic cross-section. A generic-cross-section file (GCSF) captures constraints for specific layer types. Currently, a GCSF supports four types of layers...

  • Manual entry of components

    Is there any way of manually adding a component to an Allegro PCB design using PCB Design XL in the same way that you could in OrCad Layout. I have been able to copy a footprint but the component is unassigned (R*) and I cannot find how to assign it a new part number and to connect nets to it. In Layout...
