you problem is the seting of LD_LIBRARY_PATH
 

I already set LD_LIBRARY_PATH to <inst_dir>/tools.lnx86/lib

Thanks

Eventhough I set LD_LIBRARY_PATH I still get the error.
 

Give the following a try.

Use these cmds to search for the location of the lacking stuff.
$> su root <cr>
$> find / -name libudm.so -print <cr>
Append the <path> directory of libudm.so into the LD_LIBRARY_PATH environment. If there are mutiple findings, then choose the appropriate one to use for.
 

Hi,
I was able to get rid of this libudm.so error by setting LD_LIBRARY_PATH variable.
But when I run ncsim it throws another error....

ncverilog: 05.10-s006: (c) Copyright 1995-2004 Cadence Design Systems, Inc.
Loading snapshot worklib.fa:v .................... Done
ncsim: *W,TCLINT: TCL init scripts not found, check TCL_LIBRARY.
ncsim> run
ncsim: *W,RNQUIE: Simulation is complete.
ncsim> exit

Can anybody suggest me how to get rid of this?

Thanks in advance.

I had a similar problem when I tried to run regressions via the AT command. It wasn't picking up my environment variables - specifically the LD_LIBRARY_PATH. I also had an incompatibility problem which I deleted the INCA_Libs directory and then it worked fine.

If you're getting the libudm.so error, it's probably a problem with you environment variables.

You may solve this problem by following steps. For example, I met this case:

>nclaunch
/usr/local/eda/ldv51/tools.lnx86/nclaunch/bin/nclaunch.exe: error while loading shared libraries: libvisadev.so: cannot open shared object file: No such file or directory

then exceute the following command:

> find LDV51_INSTALL_DIRECTORY -name libudm.so -print <cr>

you'll get

LDV51_INSTALL_DIRECTORY/tools.lnx86/inca/lib/libvisadev.so

then add LDV51_INSTALL_DIRECTORY/tools.lnx86/inca/lib/ to LD_LIBRARY_PATH, such as

setenv LD_LIBRARY_PATH $CADENCE/tools/lib
setenv LD_LIBRARY_PATH $CADENCE/tools/dfII/lib:$LD_LIBRARY_PATH
setenv LD_LIBRARY_PATH $CADENCE/tools/simcontrol/lib:$LD_LIBRARY_PATH
# add the next line, where $CADENCE is just LDV51_INSTALL_DIRECTORY
setenv LD_LIBRARY_PATH $CADENCE/tools/inca/lib:$LD_LIBRARY_PATH
setenv LD_LIBRARY_PATH /lib:/usr/lib:/usr/dt/lib:$LD_LIBRARY_PATH

good luck!

hi sunny656,

i couldn´t found LDV 5.1 ISR on the cadence ftp server.
There are only complete and overlay packets.
Please tell me the directory path.

Thank


it's gone for a long time. The oldest version is IUS 54
 

hi. I had the same problem.
ncsim: error while loading shared libraries: libudm.so: cannot open shared object file: No such file or directory

and I had already set the LIBPATH to /tools.lnx86/lib which contained the libudm.so file.
Pls anyone can help me to fix it.
thanks.
 

After installation of IC6 & mmsim, I met a similar problem.
Having trying to start simulation from ADE it replied as:

*Error* The 'spectre' executable that you are using is an older version.
Use MMSIM60 or later version of Spectre with this release.
To check the spectre version, run 'spectre -W'

Typing 'spectre -W' in the terminal gave:
necessity to have the library 'libvisadev.so'.
As soon as I found this library in the hierarchy of cds6, I set
LD_LIBRARY_PATH=$CDS_INST_DIR/tools/dfII/verilogIn/lib

After that 'spectre -W' gives
sub-version 7.1.x.x

Nevertheless nothing changed at simulation starting in ADE.
But although standalone starting spectre works fiine.

Are there any suggestions to fix?
Thanks in advance.
