What's Good About DEHDL’s Constraints Comparison? The Secret's in the 16.6 Release!
The Allegro 16.6 Design Entry HDL release provides designers a mechanism to compare two databases for constraint differences. The databases that can be compared are of the following types: • Schematics (.cpm) • Layout design (.brd, .sip, .mcm) • Constraints Manager Database (.dcf, .tcf...

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...

What's Good About OrCAD Capture’s Signal Integrity Flow? The Secret's in the 16.6 Release!
With the 16.6 release, you now have the capability of utilizing the PCB SI tools (SigXP) to work with topologies and constraints in the OrCAD Capture environment. Capturing constraints early in design cycle is important for the following reasons: Quality challenges as the design cycle for any PCB product...

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 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...

A Shorter, Predictable Design Cycle for Complex PCBs - Dynamic Phase Control
This is second in a series of blog posts about making your design cycles shorter and more predictable for increasingly complex PCB designs. In my last post I talked about using ECSets and Topology Apply capabilities for high-speed standards based interfaces such as DDRx and PCI Express. Continuing on...

A Shorter, Predictable Design Cycle for Complex PCBs -- Electrical Constraint Sets (ECSets)
This is the first in a series of blogs focused on how you can make your design cycle predictable and shorter for PCB designs that are increasing in complexity. PCB designers have to deal with increased complexities while design teams are dispersed geographically, and the time to finish the design is...
