What's Good About Allegro DFM/DRC Updates? 16.5 Has a Few New Enhancements!
Allegro PCB Editor has been enhanced in the 16.5 release with three (3) additional DRC checks and an enhanced DFA utility for a 4th DRC entry, and now allows backdrilling from any layer. Read on for all the details … Max Neck Length DRC Presently, the Max Neck Length constraint is applied on a...

What's Good About Allegro GRE Constraint Region Support? It’s in the 16.5 Release!
The 16.5 Global Route Environment ( GRE ) now allows or prohibits tuning in constraint regions. This functionality was designed to help PCB designers prevent delay routing in constraint regions. This is generally desirable as the space is so tight in the BGA via field that there is little room and what...

What's Good About Allegro PCB Router Inset Vias? See for yourself in 16.5!
Another high density interconnect (HDI) technology that has gained popularity is inset vias. The 16.5 release has provided new commands added in Allegro PCB Router to support inset vias. Via in Pad pattern has been very popular due to its clear advantage of offering lower parasitics as compared to other...

What's Good About Allegro Differential Pair Updates? Look to SPB16.5 and See!
The 16.5 Allegro PCB Editor release adds differential pair phase tuning as an alternative to using the mouse guided delay tune command, and also quality improvements for transitions at region boundaries. I’m providing a quick summary this week of these enhancements. Differential Pair phase tuning...

What's Good About Allegro GRE Disabling Bundle Compression? It’s in the 16.5 Release!
With the SPB16.5 release of Allegro Global Route Environment (GRE) , you can now prevent “Compact” routing on bundles that don’t need it. This compact routing functionality was designed to keep the delay patterns as tightly packed as possible as part of a methodology that preserved...

What's Good About Retaining Electrical Constraints? Look to SPB16.5 and See!
Currently, many of the SPB products support extended nets, better known as Xnets. Xnets are created automatically when a signal model is assigned to a component and that signal model defines that a connection is to be made between two pins of the component. This creates an Xnet that connects the nets...

What's Good About APD’s Assembly DRCs? You’ll Need the 16.5 Release to See!
Prior to the Allegro Package Designer (APD) 16.3 release, Design Rule Check (DRC) markers created by Assembly Rule Checks had to be external DRC markers since no constraint IDs were associated with the ADRC constraints. In the 16.3 release, Constraint IDs were created for each of the rules. It enabled...

What's Good About Allegro GRE Route Around Etch Shapes? See For Yourself in 16.5!
This new 16.5 Global Route Environment ( GRE ) functionality was designed to allow the router to obey plane shapes that are found on signal layers. This is especially useful when a user is trying to work a breakout/route solution and maintain the power integrity of today's high power chips. This...

What's Good About Allegro PCB Router Region Rules? 16.5 has a few new enhancements!
Designers normally create nets or groups of nets to assign constraints. This leads to nets rules, net class rules, and net class to class rules. As the size of physical symbols (footprints) is reducing, the need for region specific rules is also increasing. When all these constraints are applied, the...

What's Good About Allegro PCB Editor Associative Dimensioning? Check Out 16.5!
With the Allegro PCB Editor SPB16.5 release we've enhanced the existing Allegro drafting dimensioning capabilities, so that when a dimension is created involving one or more design database objects the dimension will subsequently remain internally ‘associated’ with those objects as well...
