28 Aug 2007 10:46 libvpi.so

I want to use the NC-Verilog to generate a backward SAIF file for the PowerCompiler.
so I must add a number of PLI functions which are integrated in libvpower.so into my testbench

in the command line I wrote that:

setenv LD_LIBRARY_PATH /tools/.../.../vpower :$LD_LIBRARY_PATH
ncelab ........ -loadpli1 libvpower:read_rtl_saif.read_rtl_saif

but when I run the command ,the terminal echoes:
Failed to load dynamic library libvpower
ld.so.1: ..............................fatal : libvpower.so:open failed no such file or directory

I have checked the path of libvpower.so ,and it was there.
I'm confused !!
any one can help me?

Don't do it in the command line, try adding it in your .cshrc

Perhaps , you should set path of lib*.so for your simualation.

check whether u have -access +rwc switch in your ncelab command else it cannot open the file specified.
Also check whether u r using kshell mode as u r using setenv.
for bash u need to use export command.

@Wenf.yeh , see if the information below helps you fix the error.

ncelab: *E,NOTSYT reporst libgcc_s.so.1 is missing

Error Message:
$hello;
|
ncelab: *E,NOTSYT (./test.v,5|10): Unrecognized system task or function (did not
match built-in or user-defined names) [2.7.4(IEEE Std 1364-2001)].
If item was defined in a shared-object library, the problem could be:
ld.so.1: ncelab: fatal: libvpi.so: open failed: No such file or directory
ld.so.1: ncelab: fatal: libgcc_s.so.1: open failed: No such file or directory.

Problem statement:
When trying to link the pli with the verilog code user gets the above error at the
ncelab stage.
The shared object library is created using gcc.
For example:
> gcc -shared -o libpli.so -fpic -g veriuser.o pli.o

Note: Here 'veriuser.o' and 'pli.o' are the object files.

Solution:
To resolve the above error please add the following path to the LD_LIBRARY_PATH:
/<install_dir>/tools/systemc/gcc/install/lib

the clue here was to add to the search path the location of libgcc_s.so.1.
Your local environment may include other locations your company uses instead,
buy the above location is delivered with the IUS tool stream for gcc users.

Look for the new irun command to simplify this PLI integration issues, I believe CDN has documentation on this new use model.

If you still need help, consider posting at cdnusers.org or send to CDN support.
