the follow document is test report on Linux/winXP (Not use EDA tool
but you can find video /audio coding performance between linux & winXP )

https://www.anandtech.com/linux/showdoc.aspx?i=2114&p=1

from this test report , some application on FC Suse or winXP
have the equal speed .. but I don't know if use Hspice
on Linux & winXP which will have better performance ??

EDA on linux , I think will stable than winXP . but if only consider
simulation speed .. which platform is fast for EDA design

Ya , it is a very interesting issue!

But it is very diffcult to measure the real result.
I think it depends on the OS schedule algorithm and the optimize level when the program is compiled !

1. Have seen small differences in Modelsim.
2. Hsim is 20-30% faster on W2k
3. Matlab is nearly identical beside the grafic which is much better on W2k

Others are not known to me.

This was for the same type and speed of processor ??

I have simulated my logic with ModelSim at WinXP and Linux 7.2.

My pc is P4 2.4C and 1GB RAM.

Simulation is some fasterat at Linux.
about 20% ??

I find (and heard from others) that results vary on a case by case basis. In any event, the OS you use is pretty much predetermined by the type of work you do. FPGA/Board - Windows, IC/ASIC - Linux/Unix...

I should add that Server 2003 is much faster than XP aswell when configured correctly for use as a workstation. In terms of stability I have found 2K3 better than XP when running EDA applications (even though no service pack has been released for 2K3 and using XP drivers for some of the H/W). As for linux iam hearing REDHAT RHEL 3 is rock solid including the Opteron version, software has started to trikle through for RHEL 3 and there is much more on the way.

Re: eda on linux is fast

I try the same case on winXP & linux

I use hspice demo file -->apps/pll.sp
but .tran sim time from 500us --> large to 5ms
for long time simulation and .option probe
reduce dump file size

on the same PC Intel P4 3G + Dual channel 1G DDR400
+ scsi HD

winXP use 385 sec (hspice 2001.2)
redhat 8 use 280sec (hspice 2003.9)

Linux run fast than winXP , but linux is new version hspice ..
but I think Linux will fast than winXP ..

By the way , Have anyone use K8 ? someone said K8 run PLL is fast
who have athlon64 3000+ .. can you test this demo file

Your comparison isnt really fair, I agree linux will be faster however your comparing Hspice v2001 to v2003 and probably has a good deal to do with yor results. Windows has gotten better for EDA but anything to do with IC design should be done on LINUX. As for the K8 id watch the chipset you go for very carefully and I suggest going for plain old AMD chipset (8000 series) based Opteron/Athlon 64 combination and avoid anything else such as the nvidia and especially the VIA as support in RHEL 3 is non-existant.

I try others case

the same spice netlist

winXP + hspice 2003.9 + P4 1.8G ==> 48sec
linux + hspice 2003.9 + P4 3G ==> 18sec

I think you can get linux work WORSE than XP if you don't set it well, and get DAMM FAST is you set it well.

First I you want to linux run fast you can get rid off all the daemons you dont use, even better don't use X if you want speed in a nonX procedure.

And there's the real difference try to compile things using runlevel 1 and you will se how it gets real fast compared to runlevel 3 or 4(usually gdm, kdm...etc)

And that's the point on linux, you can switch on that task without even rebooting the machine and you can get rid off all the damm daemons that eat your resources and get plenty of space to your app.

That can be done increasing the priority of your task when done, but I can't recall If that comed naturrally with every kernel since I use RT.

With that you can give your task the top priority and it will go real fast, but your machine will get clogged until you task ends.
(I mean not even taking care of mouse, keyboard, etc)

So before you try to compare windows to linux, remember that linux is made of many parts and VARY A LOT FROM PLACE TO PLACE and your knowledge on the base of Linux give you more tricks that you ever could imagine on windows.

I think no need to prove anything. Sure, the EDA on linux is faster. Y? The answer is Linux is the variant of UNIX.

I think andy2000 result was not read carefully:

winXP + hspice 2003.9 + P4 1.8G ==> 48sec
linux + hspice 2003.9 + P4 3G ==> 18sec

it is winXP on 1.8G P4 versus linux on 3G P4

If the compiler used for both OPs have the same optimizing settings the result should be very similar. So it is more a question of the toolvendor.

just a personal experience
a same spice netlist simulation running under pc linux is 3x faster than under workstation
don't know why? can any explain?

I run some tests and got mixed results for HSpice, using the same machine (P4, 2.8 GHz - dual boot). For some circuits, winXP were faster but for others, linux (FD2) were faster. I think it depends how the OS is handling the different process running at the time of simulation.

really , linux fast than windows ...
ncverilog in linux fast than windows ,
1.5~2.0X and more stable
