error while running spectre using ic 5141

Do what it suggests in the "Alternatively" part. Go to the netlist directory (your "project directory" then cellName/simulatorName/viewName/netlist - you should be able to see the path from Simulation->Netlist->Display) and then invoke the "runSimulation" command from the UNIX prompt. Often this kind of error is caused by shared libraries being missing on the machine you're running on, or something similar.

By running from the UNIX prompt, you can often see what is causing the simulator to fall over before it even has a chance to create the log file.

 if we open runsimulation ,its showing following lines --

"spectre -env artist5.1.0 +escchars +log ../psf/spectre.out +inter=mpsc +mpssession=spectre1_5883_3 -format sst2 -raw ../psf  +lqtimeout 900 -maxw 5 -maxn 5 spectre input.scs "

if we run in linux terminal,error is,,

 "spectre (ver. 5.10.41.121508 -- 15 Dec 2008).
Includes RSA BSAFE(R) Cryptographic or Security Protocol Software from RSA Security, Inc.

Error found by spectre.
    Invalid command line argument `-maxw'.
        Use `spectre -help' for more information."

i a not getting any maxw in help.. 

The -maxw and -maxn arguments should only get added if you're using an MMSIM version of the simulator (e.g. MMSIM70, MMSIM71); if using IC5141 spectre, these should not get added.

I'm wondering if there is some peculiarity which is causing it to think you have MMSIM in the path, but it's not actually in the path. 

Can you do:

echo $PATH

in your UNIX terminal, and paste what it says here?

I'm wondering if it might be some peculiarity with having MMSIM in your path, but not having the tools link present (note, after this came up last week, we should be fixing the missing tools link shortly).

It's really advisable to use spectre from an MMSIM release (e.g. MMSIM71) rather than the one in the IC5141 installation, which is rather old. As you can see from the error message when running runSimulation, it is trying to run the spectre from the IC5141 installation.

ya i am trying to use from MMSIM71 only,,i added it script file...

By using above command ,,the foll,,lines are coming,,

 "[root@vlsi6 ~/test]$ echo $PATH

Indeed. From a quick experiment, the "feature file" (which is how ADE determines what features the simulator possesses, so that) for MMSIM7X is found even if the path is after IC5141 (because there is no "feature file" in IC5141). But the simulator would get picked up from IC5141 (as Andrew said).

So it will think it has the features of MMSIM, but actually run the IC version of spectre.

So all you should have to do is put the MMSIM path first.

I guess this is really a bug, but since it's something that doesn't make any sense to do, it's very unlikely to get fixed (given where IC5141 is in its life cycle).
