What's Good About Allegro GRE Rake Functionality? You’ll Need the SPB16.3 Release to See!

Comments(2)Filed under: PCB design, SPB, Allegro PCB Editor, Allegro, PCB Editor, PCB, SPB 16.3, Allegro 16.3, layout, "PCB design", SPB16.3, GRE, global route, routing

The SPB16.3 Global Route Environment (GRE) Expanded Rakes functionality provides better visualization of the connectivity of the Bundles. In previous versions, this functionality was only provided when the user moved the gather point. Now this functionality is provided at two levels – the design level through Design Parameters, or at the individual bundle level through the Bundle’s properties.

For more information, read on …


If you set the Expanded Rake view at the Design Parameters level, it will by default set the Expanded Rakes to be visible when you create a Bundle. You view the Design Parameters Expanded Rake setting by using the Pop-Up (RMB->Quick Utilities->Design Parameters) or Setup->Design Parameters->Flow Planning->Default Bundle Properties.


If you set the Expanded Rake view at the Bundle Properties level, it will set the Expanded Rakes to be visible regardless of what the Default Parameters setting is. You can get to the Expanded Rake settings on the Bundle properties dialog by hovering over a bundle or bundles and RMB->Bundle Properties.


Also, when doing other Bundle Edit functionality such as Split Bundle or Copy Flow, the current setting of the Expanded Rake will propagate forward to the new Bundles.

Please share your comments on this new capability.

Hi Jerry,

This message is not related to this blog since I haven't find your e-mail address. I wonder if you are going to attend PCB WEST 2010 conference. If so I wish to meet you there. We will join this conference. Actually I am glad if you will. Best regards

Hi Ahmet,

Good to hear from you again and to see that you're reading the PCB Community Blogs!

I'm not scheduled to attend PCB West 2010, but there will be several expert PCB Application Engineers from Cadence - so feel free to connect with them.
