After Cadence acquired Sigrity in July 2012, we heard many of the same questions: What is happening with my favorite Sigrity tools? Is Cadence going to change the functions and features I’ve been working with several years? If I’m not a Cadence Allegro user, can I continue using Sigrity tools without purchasing any other tools? If I’m a Cadence Allegro PCB SI user, what changes am I facing now?
The new Allegro Sigrity SI solution is comprised of the Allegro Sigrity SI Base and three options: Power-Aware SI option, Serial Link Analysis option and Package Assessment option. In the base product of the new SI solution, Allegro and Sigrity technologies are highly integrated, with the same constraint manager used by Allegro PCB Editor, as well as a full range of analysis capabilities that enables early identification and resolution of electrical performance. However, if you need detailed analysis, compliance and assessment solution, you can choose from the three options powered by Sigrity technologies to accomplish your design analysis goal.
In an interview of Cadence Product Marketing Director Brad Griffin by EDACafe, Brad shared his enthusiasm and vision of Allegro and Sigrity integration with the audience. “Sigrity is a world-class signal integrity and power integrity solutions provider.” he said, “so the integration of Sigrity and Allegro brings design and analysis together. If you are a board designer, you don’t need go to other tools and learn all the analysis expertise. Instead, you can just bring in some signal integrity technologies from Sigrity to finish your design work. If you are an analysis expert and you find the design is not working and you need to make changes, the Allegro technologies are there allowing you to make changes according to your needs. Allegro and Sigrity integration bridges the gap between designers and analysts.”
According to Brad, the integration of Allegro and Sigrity Signal Integrity solution is the first step of the whole integration plan. The next step will be leveraging the state-of-the-art Power Integrity (PI) technologies from Sigrity to strengthen Allegro PI solutions. This Allegro Sigrity PI solution is expected in 2013.
So for Allegro users, the integration of Allegro and Sigrity will bring great benefits. Designers can enjoy a complete design, analysis and compliance signoff solution for complex PCB and IC Packages that covers SI and PI effects. At the same time, non-Cadence users don’t need to worry that their familiar and favorite Sigrity tools will disappear, as Cadence will continue enhancing and marketing Sigrity technologies to existing Sigrity users as standalone tools.
In summary, yes, Allegro and Sigrity are better together. But if you are comfortable using one or both of them separately, you can continue doing so. It is your choice.
