Subject: Novas Debussy & Verdi, Veritools UnderTow, DAI SignalScan
DEBUG ENVIRONMENTS -- This is everything with a Verilog/VHDL simulator that
is NOT a linter nor a code coverage tool -- generally these are the waveform
viewers and debug *environments* closely tied into the simulator.
2007 - "What waveform/debug tools do you use? Veritools Undertow or
Novas DeBussy & nSchema & Verdi vs. only the waveform/debug
built-into Cadence, Synopsys, Mentor, Aldec? Be specific."
Cadence built-in debug : ############################## 29.6%
Cadence DAI SignalScan : ## 1.7%
Synopsys built-in debug : ################################# 33.2%
Mentor MTI built-in debug : ########################## 26.3%
Aldec built-in debug : ### 2.5%
Novas Debussy : ################################# 33.1%
Novas Verdi : ##################### 20.8%
Novas nSchema : ##### 4.5%
Novas nWave : # 1.3%
Novas Siloti : 0.3%
Veritools UnderTow : ### 2.8%
Bybell GTKwave : # 0.8%
Veripool Dinotrace : # 0.6%
Axiom built-in debug : # 0.8%
The selling-ice-to-Eskimos guys in this space are the Novas folk. Obviously
it's no too hard for them, though. Here's their 2005 and 2007 data:
2005 - Novas Debussy : ############################## 30%
Novas Verdi : ######### 9%
Novas nSchema : # 1%
2007 - Novas Debussy : ################################# 33.1%
Novas Verdi : ##################### 20.8%
Novas nSchema : ##### 4.5%
Novas nWave : # 1.3%
Novas Siloti : 0.3%
Look at that. Verdi is up over 2X. nSchema up 4X. Generic DeBussy up 10%.
Mind you, it's not all sunshine at Novas -- another way to look at this data
is that their best product (Debussy) is still missing in 66.9% of projects.
Either way, how these salesdroids at Novas, Atrenta, and Synplicity can win
against "free" repeatedly is one of The Great Mysteries of EDA.
Novas Debussy and Verdi
- [ An Anon Engineer ]
ncsim, sometimes use verdi
- Jin Song Liu of Agere
built-in tools of MTI
- Andreas Dieckmann of Siemens
Novas Debussy & Verdi + Modelsim built in
- [ An Anon Engineer ]
We use Debussy and SignalScan. We have tried VCS/DVE in the past, but
wasn't stable. We'll need to try it again soon to see if it improved.
- Dan Steinberg of IDT
Built debuggers- Mentor/ SimVision/ DVE, virsim
- [ An Anon Engineer ]
Novas Debussy (I mean Verdi)
- Dan Joyce of Hewlett-Packard
Synopsys DVE waveform/debugging environment for current designs.
Cadence SignalScan for supporting old designs.
- [ An Anon Engineer ]
Just CADENCE Simvision
- [ An Anon Engineer ]
Novas Verdi
- [ An Anon Engineer ]
Use built in waveform viewers when using Cadence, and use Novas Debussy
for debugging formal counter examples.
- [ An Anon Engineer ]
Built in Mentor ModelSim.
- Steven Snyder of ITT
Synopsys DVE
- Ambar Sarkar of Paradigm Works
Depends on the team member. Some use Novas DeBussy & Verdi, some
just use simvision.
- [ An Anon Engineer ]
I use Cadence Simvision.
- Jeff Bray of Analog Devices
simvision from cadence and undertow
- [ An Anon Engineer ]
Use Cadence Simvision. Debussy/Verdi is too expensive. Undertow is a
good tool at a right price, but with a lot of minor bugs.
- [ An Anon Engineer ]
simvision mostly, sometime undertow.
- Gautham Kamath of Cirrus Logic
We are transitioning from DeBussy to Undertow. Many DV people are using
built-in DVE and Simvision for testbench development. Undertow is used
for waveform viewing by RTL team, and also assertion development by DV
(when it's not crashing.)
- Kelly Larson of Analog Devices
Veritools Undertow
- Joe Wong of Chrontel
Novas Verdi, even though building the symbol libraries is always a
pain, and I _hate_ the mouse button assignments they selected.
- [ An Anon Engineer ]
Cadence Simvision
- [ An Anon Engineer ]
Have been using SignalScan from Design Acceleration (Cadence) for
years but are now gradually switching to Synopys DVE.
- [ An Anon Engineer ]
DDD, printf and simvision
- [ An Anon Engineer ]
Novas Verdi
- Paul Davies of Cisco
Cadence Simvision and Debussy nWave
- [ An Anon Engineer ]
Novas Debussy/Verdi and Modelsim built-in (latter especially if
it comes to delta-cycle analysis)
- Helmut Reinig of Infineon
Simvision from Cadence and Virsim from Synopsys.
- [ An Anon Engineer ]
Built into Cadence and Mentor
- Greg Tumbush of AMI Semiconductor
Only Mentor Graphics modelsim. The other simulators are mostly
run in batch only.
- [ An Anon Engineer ]
Mix of Veritools Undertow, Novas Debussy & nWave, Cadence
SimVision, Synopsys DVE, Synopsys TurboWave
- [ An Anon Engineer ]
Cadence NCsim / SimVision
- Nathan Nipper of Harris
Synopsys Versim and DVE
- [ An Anon Engineer ]
Built-in Mentor.
- Kishor Mistry of Gennum
Mentor-modelsim + Novas Debussy
- [ An Anon Engineer ]
Novas Verdi nSchema and nWave as the schematic and waveform
viewers, resectively for debugging.
- Tim Murphy of Agere
I mainly use Synopsys VCS or DVE. We have Cadence, Modelsim, and
Debussy available. This is primarily due to old habits rather than
based on evaluating the best tool.
- [ An Anon Engineer ]
Mostly Synopsys DVE, but we still have a few Undertow users left.
- [ An Anon Engineer ]
Cadence Simvision
- George Gorman of LSI
Cadence Built In
Synopsys Built In DVE, some still use VIRSIM (don't ask me why)
Veritools Undertow also used quite a bit.
Mentor Modelsim Built In
- [ An Anon Engineer ]
We mainly use Synopsys DVE. On occasion Debussy is used
- Sam Bishai of Cisco
We use the Novas tool suite and the built-in Cadence waveform/debug
tool. We will probably start using Synopsys' relatively new DVE tool.
- [ An Anon Engineer ]
Veritools and Novas, depending on the individuals' preferences.
Also some use of SNPS Tmax schematic viewer with its simulation
data applied, to debug scan ATPG/sim issues.
- [ An Anon Engineer ]
We use DeBussy
- Marty Deneroff of D.E. Shaw
Open source: gtkwave. The user interface is clunky compared to Verdi
and it doesn't support a COMMONLY AVAILABLE efficient waveform output
format, leading to waveform file size problems, but it is what I have.
