( DAC'18 Item 2b ) ------------------------------------------------ [12/14/18]
Subject: Breker TrekSoc is slipping in the PSS Wars is #2b for Best of 2018
NOT ALL IS LOST: In the earlier section (DAC'18 #2a), I cited how from the
user comments, Perspec is growing while Breker is falling behind:
PSS Tool Word Counts in DeepChip "Best of" 2017 vs. 2018 EDA User Survey:
Cadence Perspec 2017: ############################### (3,097 words)
Cadence Perspec 2018: ##################################### (3,712 words)
^---- damn it!!!
Breker TrekSoC 2017: ############### (1,476 words)
Breker TrekSoC 2018: #### (381 words) <---- double damn it!!!
And that it's rumored that AMD just switched from Breker over to Perspec.
But that's not the whole picture. My spies have told me some very big names
like HiSilicon and IBM and Cavium have renewed their Breker licences.
Also, Breker recently hired Bill Rothenberg -- a veteran EDA sales guy from
SDA, Synopsys, and Jasper -- as their new VP of Sales. (And since Bill's a
*veteran* sales guy -- I *know* he wouldn't have joined Breker if he didn't
sense some serious $$$ there.)

QUESTION ASKED:
Q: "What were the 3 or 4 most INTERESTING specific EDA tools
you've seen this year? WHY did they interest you?"
---- ---- ---- ---- ---- ---- ----
We piloted Breker TrekSoc on a multi-million gate ARM Based SoC. The
tool helped us in porting our top level simulation tests into our
Zebu emulation (FPGA) and post silicon environment.
Breker helped drive down our Zebu emulation man-power requirements
considerably. The porting from top level VCS simulation to Zebu
emulation was pretty straight forward and seamless.

I am an engineer at [name deleted] and I have evaluated Breker Systems
portable stimulus tool called TrekSoc.
Their cache coherency app provides a lot of interesting memory traffic
as borne out by our functional coverage - right out of the box. TrekSoc
was easy to set up and to reuse our tests among different SOC configs.
But -- It was more of a challenge in Breker to develop individual test
recipes using their current graph methodology if the tests happened to
do things other than cache coherency.
---- ---- ---- ---- ---- ---- ----
While I have not worked intensively with the TrekSoC tool itself, we've
used the underlying Trek graph-based verification engine to generate
interesting verification scenarios for years.
We've had great success using the Trek tool as a base for what we ended
up calling "graph-based verification methodology". This allowed us to
easily specify verification scenarios that very well combined both deep
state space exploration (by generating directed sequences when required)
as well as allowing randomization of these sequences.
We especially liked the C++-friendly input language of the tool as well
as easy integration into our existing CDNS/MENT verification framework,
as well as the excellent support we had gotten from the Breker team.

Breker
We have been using graph based verification at our company in various
applications across complex designs and multiple projects and have
gotten very good results, particularly in coverage. The Cache Coherency
App in Trek has been an important part of our verification methodology.
---- ---- ---- ---- ---- ---- ----
On Cadence Perspec vs Breker TrekSoC, we're for Breker.
We have been using TrekSoc from Breker for quite some time now and were
able to generate directed tests using graphs. The tool is also very
easy to use.

We're a Breker house. Have been for years.
