Subject: 8 Users Like The Idea of NC-SIM with Specman "e"

As a user, I'm not sure. I like Verisity and I'd hate to see Cadence
bury them. Of course, if they add 'e' to NC-Verilog (a la Synopsys
adding OpenVera to VCS) then I'll be happy. But that could never
happen soon enough.

Good for Verisity's testbench tool to be sold with Cadence simulator.
Not good for Verisity's SpecXsim and SpecXtreme products obatined
from last meger with Axis Systems because they overlap with Cadence
product offerring and wil cause confusion and uncertainty to customers
for these overlapped products for a while.

As an EDA user I think that this merger may be good if Specman is
integrated into Cadence design flow. If it is left in it's current
"disconnected" from the design flow condition then I don't expect any
good from this merger. This happened before with Module Compiler.
For me diving into Specman was always questionable because it required
a separate design effort which could not be used in synthesis or other
functional verification. It also may be because we have no intricate
interfaces in our design.

This will give Cadence a tool package of NC-SIM/Specman similar to
Synopsys VCS/Vera. Will Cadence build e into NC-SIM as Synopsys is
doing with their NTB? What will Cadence do with SpeXsim? Will Mentor
be dependent on Cadence Specman or Synopsys Vera for verification
platform development? Or will they focus on System Verilog constructs
(which I find lacking unless they implement RVM/VMM as well). Some
things to watch there.
It will be interesting to see how the new management changes the
Verisity team's research and development group. Verisity has been very
interested in partnering with us as IP developers to develop new
verification technologies. I've found other vendors to be reluctant to
develop something new unless I can prove a potential customer base.
We'll see if Cadence maintain's Verisity's philosophy of "build it and
they will come".

I think this is good news because it gives Specman a better chance to
compete with VCS/Vera. I've used both 'e' and Vera on projects, and
it seems like 'e' was more useful and powerful, but it's hard to
justify its extra cost. Since VCS already has native support for most
of Vera, I'm hoping Cadence will be able to quickly come up with a
competitively priced NC-SIM with native support for 'e'.

I'm not a Verisity fan -- mostly because the verification language is
binding. I can only hope Cadence makes this just an option in NC-SIM.
Perhaps, Cadence will make it synthesizeable and then we can use it
on Palladium. I wonder what will happen to the Axis box now?

Good if the Verisity technology is integrated into the legacy tools
like NC-SIM with the minimum extra charge (although we don't have
Specman Elite, we'd like to use it). Otherwise it may be bad.

My thinking, prior to the the announcement, was that "e" would become
just another footnote in EDA history.
Now, Cadence may be able to put new life into Specman, perhaps by doing
a Synopsys and pushing a high performance combo of NC-SIM and "e" (like
Vera and VCS or like their System Verilog vision.)
