I am a fresh man to use Cadence NC_Launch. Now there has a error when I use NC_Launch to simulation Verilog code, the error is :
ncsim: error while loading shared libraries: libudm.so: cannot open shared object file: No such file or directory
ncverilog: *E,SIMERR: Error during Simulation (status 127), exiting.

I do not know why this error occured?

this is ld library path set error, nc can't find where has libudm.so. so you frist goto nc install path, then

$> 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, aravind: I had already copy cds.lib and hdl.var file to the directory which I setup nclaunch. at the same time, I add a sentence in the cds.lib file:
DEFINE /my project ./work.
but the nclaunch still give me a error.

As other poster noted, this is an issue with your LD_LIB Path setting, try his suggestion. In general, it should be in:

$CDS_INST_DIR/lib, $CDS_INST_DIR/inca/lib (or some thing similar).
