AMS designer: ncelab error
Dec 01^st, 2009, 7:08am

hi, everyone,

I am trying to simulate the VerilogAMS models for the Phase-locked loop provided in this website (dg-vamsA-4, listing02-09) .

First I compile the files using ./compile.sh provided in the directory. No problem.
Then when I run "run-me-with-gui", an error occurs, showing there is a problem during "ncelab" (see below). I don't know what is "Spectre Simulation Image Generation library", and why they need this.

Some other information:
I created a worklib subdirectory, and there is a .pak file . For hdl.var and cds.lib file, I just change the $AMSHOME to my Cadence install directory.

Anyone have an idea?
Thanks in advance
Bo

Hi Couragebo,

There is something wrong in your settings as far as I can read:

No, this is wrong, the AMSHOME must be pointing to the IUS install directory rather. Besides, you do not need to miss about any of the hdl.var, cds.lib files. They should be working fine as provided.

To get yourself sorted out you need to:

1. Start a new Unix terminal
2. Delete your run directory and start from a new unziped/untared archive. Leave all the files as provided
3. Acquire the IC stream, i.e. where the cadence DFII is installed
4. Acquire the IUS stream, i.e. where ncvlog, ncelab .. are installed.
5. Updated your LD_LIBRARY_PATH to get the $AMSHOME/tools/lib added.
6. run the run-me-with-gui script.

All should be fine if you go carefully through the above steps.
Please give it a try and let me know.

BTW, are you a RHEL or a SUSE user ?

Cheers,
Riad.

Hello, Riad,

I just came back to update my post, because I realized that I was wrong �about $AMSHOME. And you were already here and found this bug! Thanks for the quick answer. Wink

�You are definitely right.

In fact, in my machine, AMSHOME is not defined (when I use it in cds.lib or hdl.var, an error tells me that AMSHOME is not found), and coincidentally I found the ../tools/inca/files/.. in the Cadence installation directory, that's why I changed AMSHOME.

Anyway, thank you very much for the precious suggestions, i will try them and feedback here soon. �
Btw, I am using RHEL.

Bo

My problem was that $AMSHOME and $LD_LIBRARY_PATH are not well defined, as pointed by Riad. Thanks Riad for the great help! Cheers Bo

hi, everyone,

I am trying to simulate the VerilogAMS models for the inverter provided in this website ( dg-vams4-1, listing01) .

First I compile and elabrate the files with-gui. No problem.
Then when I run it with-gui, an error occurs, showing there is a problem (see below).
*W,SST2DC: Unable to load SST2 communication library: /usr/ius/tools/lib/libdcapi.so: cannot open shared object file: No such file or directory or file is not valid ELFCLASS32 library.

Some other information:

I just change the $AMSHOME to my IUS8.20 install directory.

Anyone have an idea?
Thanks in advance

thank geoffrey_coram for you reply.
for me:
cadence install path: /usr/cadence
ius8.2 install path: /usr/ius

I found the file "/usr/ius/tools/lib/libdcapi.so" with a arrow. what is libdcapi.so?
[root@mml 64bit]# cd /usr/ius/tools/lib
[root@mml lib]# find . -name libdcapi.so
./64bit/libdcapi.so
./libdcapi.so

/usr/pdk/listing01/cda.lib
# cds.lib
INCLUDE /usr/ius/tools/inca/files/cds.lib
DEFINE worklib /usr/pdk/listing01/work

can I make friends with you?
