Unkown icfb startup problem!! :(

[Reotaro Hashemoto]

Hi,

I finished instaling Cadence IC5.10.44 tools today on Suse 10., and
when i start any of its tools (e.g. icfb or icms ...), the CIW takes
very long time to load (takes about 5 mins on a fast P4 2GHz PC!!!).
and when it finishes, it shows in the CIW log something like the
following (the first two lines are repeated too many times, such that
they overite the previous lines!:

Loading ./.cdsinit init file from the site init file.
END OF SITE CUSTOMIZATION
Loading ./.cdsinit init file from the site init file.

*Error* load: can't access file - "leBindKeys.il"
END OF SITE CUSTOMIZATION
*Error* load: can't access file - "./.cdsinit"

Moreover, when it loads after the huge time, and i try to open library
manager, but i denyed displaying error message, in the CIW log saying:

cdsServIpc: ipcIsAliveProcess connection timeout (host::isaserver)
Waiting for ipc:0 to initialize
*WARNING* (ddsOpenLibManager) unable to connect to library manager (60
tries)
cdsServIpc: ipcIsAliveProcess connection timeout (host::isaserver)


I noticed the word: "host::isaserver" in the log, that's due to i
connect to internet via proxy MS ISA server, so, i added a host with
name "isaserver" and number is the ISASERVER IP address, but i run
tools from my machine not from the server that doesn't have linux as
well. Can this be reason to the problem??

It's not only slowness problem then, it's not functionaning at all!!!

My .bashrc contains the following lines:
CDS_ROOT=/usr/local/cdstree
CDS_INSTALL_PATH=$CDS_ROOT/tools/dfII
export CDS_LIC_FILE=$CDS_ROOT/share/license/license.dat
export PATH=$PATH:/usr/local/bin:$CDS_ROOT/tools/bin:$CDS_INSTALL_PATH/
bin:$CDS_ROOT/tools/spectre/bin
export CDS_Netlisting_Node=Analog

And i had copied the
$CDS_INSTALL_PATH/samples/local contents
to $CDS_INSTALL_PATH/local

and renamed the cdsinit file into .cdsinit and copied to my home
directory!!!

I am really tired!! I spent more than five houres installing and
trying to fix that problem!!!

BTW, I think it's not Unix distribution problem, as I have other
colleagues installed it on Suse with the same version, and same
procedures, but they don't suffer from any problems like mine, and
it's working fast and smooth!!! (but they login to internet w/o ISA
Server like me)

I'm sure that alot of experts here solved many Cadence problems
before and will be able to help me to troublshoot and solve this
problem...

Please accept my appologies for my long message, and be sure that i'm
really tired and exhausted trying to solve before i post it here!!

Thanks in advance,
Best Wishes

Hi,

After some digging through manuals,
I completely solved the problem!
It was two cross-coupled problems, Network configuration issue, and
tools configuration issue..
The first was solved by defining new host pointing to my machine on
which tools are installed (local host)
The second problem (don't laugh ) was becasue a typo in my .bashrc
and some missing pathes, the typo was that I wrote: "export
CDS_Netlisting_Node=Analog" which should be with 'M' instead of 'N'
i.e. Mode
And for pathes, i searched around the internet, and finally my .bashrc
now looks like the following:

#############################################################################################
CDS_ROOT=/usr/local/cdstree
CDS_INSTALL_PATH=$CDS_ROOT/tools/dfII
export CDS_LIC_FILE=$CDS_ROOT/share/license/license.dat
export PATH=$PATH:$CDS_ROOT/tools/bin:$CDS_INSTALL_PATH/bin:$CDS_ROOT/
tools/spectre/bin
export PATH=$PATH:/bin:/usr/bin:/usr/ucb:/etc:/usr/local/bin:/usr/
openwin/bin:/usr/X11R6/bin:.

export CDS_WAVESCAN_JRE_DIR=$CDS_ROOT/tools/jre1.42 ## I prefer this
type of waveform windows
export MALLOC_CHECK=0
export CDS_Netlisting_Mode=Analog

export LD_ASSUME_KERNEL="2.4.1" ## I found that it's much stable
rather than my current 2.6.20 Kernel !
#############################################################################################

Now the problem is solved completely, and i found that sharing my
experience in that may help to save someone else time.. hopefully...

BTW, I needed to make a copy of $CDS_INSTALL_PATH/samples/local into
$CDS_INSTALL_PATH/local as well as copying the cdsinit inside it to my
home from which i run the tool. This is to enable schematic and layout
bindkeys.

Best Wishes,
Regards,
