December 17th, 2015 by Graham Bell

It’s not a BUG, it’s a FEATURE!

John Cooley at 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:

    Wanted to check whether we could identify design bugs with Real Intent
    that were being missed before.

    Started with Ascent-Lint on one of our small a8051 microcontroller IP
    blocks which was in pure Verilog design and 17K gates in size.

    From the start, we noticed that Ascent Lint was very easy to run.
    Within minutes getting it installed we were able to run the tool on
    our a8051 with practically no time spent on set up.

    We caught a few issues even on it.  One FSM was missing a "default"
    statement.  The designer missed this issue because of an involved mix
    of pragmas and `defines in the RTL code.  Ascent Lint ran in under a
    minute to find the need to make a RTL fix for this.  There were few
    other minor FSM-related issues identified we passed those on to the
    a8051 design team. 

    Next we ran their Meridian CDC clock-domain analysis tool on our
    Ethernet MAC IP, a 40K gate Verilog design which had 4 different
    clock domains.

    ...When running Meridian to catch CDC problems, it was correctly able to
    identify our CNTL synchronizer and our other synchronizer structures

    ...The Meridian reports provided appropriate details of the violations
    without bombarding us with too much information. 

    After the end of our eval, we decided to start using both Real Intent
    tools on our next IP development project.  We also plan to recommend
    Ascent Lint and Meridian CDC tools to our consulting clients.

Happy Holidays!
