Subject: First Encounter vs. Jupiter-XT vs. Blast Plan Pro
CADENCE RULES -- Aart's been trying to push his Jupiter-XT floorplanner onto
users, but they still have a hankering for First Encounter instead:
Cadence First Encounter: ############################ 71%
Magma Blast Plan Pro: ###### 16%
Synopsys Jupiter-XT: ##### 13%
Approximately 80% of PhysOpt/Astro customers use First Encounter in their
Synopsys P&R flow and 50% of the Magma customers use First Encounter in
their Magma P&R flow.
---- ---- ---- ---- ---- ---- ----
We do not use Jupiter-XT.
- Sunil Malkani of Broadcom
We just began to use Jupiter-XT. So we cannot make a comparison at
this time. We are also having some support issues involving this tool.
- [ An Anon Engineer ]
No data against FE or Blast PlanPro. Jupiter works fine for us.
- [ An Anon Engineer ]
First Encounter is good to use.
- [ An Anon Engineer ]
don't use Jupiter, never did (after evaluating it)
- [ An Anon Engineer ]
Jupiter-XT is much improved. All three are now about even.
- [ An Anon Engineer ]
Under evaluation but it seems almost same of all three tools.
- [ An Anon Engineer ]
One of our groups is using Jupiter-XT with good results, but still find
working in Milkyway a pain (corrupted databases issues).
- [ An Anon Engineer ]
Have never compared the tools. We use Jupiter and I am happy using it.
- [ An Anon Engineer ]
We use FE. Bitten twice by Synopsys floorplanners. Will 3rd time be
the charm?
- [ An Anon Engineer ]
Jupiter is so user unfriendly compared to Magma or Cadence tools, we
refuse to consider it further. We will stick with SOC Encounter here.
- Russell Petersen of Scientific Atlanta
Jupiter XT is improving but still behind First Encounter.
- [ An Anon Engineer ]
Have not seen Jupiter improve, but do not have a lot of designs in that
phase to test it out.
- [ An Anon Engineer ]
Jupiter is OK but you have more feature using a single UI thus SoC FE
is prefered.
- [ An Anon Engineer ]
We are not a real user of Jupiter, no need for older technologies.
Newer technologies/large designs done with Magma and use of fully
integrated flow (all tools) incl. Blast Plan Pro. Good results.
- [ An Anon Engineer ]
Magma BPP 5.0 has taken a big step forward and has functions, features
and quality unmatched by either Jupiter-XT or First Encounter.
- [ An Anon Engineer ]
Jupiter is probably behind Magma and on par with Cadence.
- [ An Anon Engineer ]
We recently switched to Blast Plan Pro from Jupiter. Basically, support
for Jupiter sucked. They only addressed our issues after we decided to
switch. Jupiter has a better GUI, and is more mature. Plan Pro has some
quirkiness, but its TCL access rocks. I can do some very complex things
using their TCL interface that I could never dream of doing in Jupiter.
Unfortunately, I also find I spend alot of time using the Magma TCL
interface for cleaning up some of their basic features that just don't
quite work.
- [ An Anon Engineer ]
Jupiter-XT > Blast Plan Pro > First Encounter
- Benjamin Chen of Socle Tech.
Still prefer Cadence for layout.
- [ An Anon Engineer ]
BlastPro > First Encounter > Jupiter-XT
- [ An Anon Engineer ]
I trust Magma Blast PlanPro.
- John Schritz of Tektronix
We use Magma Blast Plan Pro and have little experience with Cadence FE.
- [ An Anon Engineer ]
FE is first choice.
- [ An Anon Engineer ]
My experience with First Encounter is dated and it was not positive. They
may have gotten better.
- [ An Anon Engineer ]
use Astro. Do not use Jupiter.
- [ An Anon Engineer ]
Jupiter-XT was poor compared to Cadence-FE. We don't rate a floorplanner
on "virtual flat" capacity. Also "virtual flat" implies that you have
quite a bit of the Verilog code done. Usually we have functional blocks
with ports and top-level routed months before the Verilog is finished.
- [ An Anon Engineer ]
I am a primary user of First Encounter. Never got a chance to try
Jupiter (although I am interested !-)
