The Switch from Atrenta to Real Intent for CDC, Lint, and X-prop

Thursday, May 12th, 2016

John Cooley’s Deepchip.com web-site likes to publish end-user experience with various EDA tools.  On May 6, he published a posting on why a designer switched from Atrenta SpyGlass to Real Intent for CDC, Lint, and X-propagation analysis.  His report details the reasons for converting to our best-in-class tool suite.

Here is the first part of the posting:

We had been using SpyGlass from Atrenta, and it worked OK for us, but we
were told by our local Real Intent sales guy that “there would be fewer
iterations for Lint, easier setup for CDC, lower-noise reporting, and
faster runtimes” — if only we evaled his tools.

REAL INTENT MERIDIAN CDC VS. ATRENTA SPYGLASS CDC

I spent one work week (5 days) evaluating Meridian CDC. We used different
designs to evaluate this tool. The first was 850K gate design that had
3 asynchronous clock domains. For the analysis setup, Meridian CDC
automatically detected all the clock/reset candidates correctly at block-
level as well as the top-level. No additions were needed for the setup
file, while our Spyglass run did require manual editing of the setup.
The Meridian runtime for this block was ~5 minutes.

The second design was 4 million gates and had 5 asynchronous clock domains.
Again the automatic clock/reset detection worked as expected. The runtime
was ~15 minutes.

Have you switched EDA tools recently?  How was that experience?

DeepChip.com Survey: “Real Intent to possibly replace SpyGlass?”

Thursday, December 17th, 2015

 


It’s not a BUG, it’s a FEATURE!

John Cooley at DeepChip.com does an annual survey of visitors to the Design Automation Conference to find out what was interesting, and the biggest lie.

In one of his roll-up articles he looked at Real Intent, Atrenta (acquired by Synopsys), and One Spin.

With acquisitions, customers get nervous and for good reason.  The support and responsiveness they get changes.  Five respondents said they were considering possibly replacing SpyGlass with Real Intent.  One user reported the following conversation:

“Your SpyGlass customer support won’t change as a result of the SNPS acquisition.” They actually said that to me with a straight face.

The article also reported a customer evaluation of our Ascent Lint and Meridian CDC (clock-domain crossing) tools. Here is a quick snippet: (more…)
