*ERROR* (AMS-1247): AMS UNL netlisting has failed --> With XCELIUM21.09

No idea (I didn't find anything specifically on this, and would need a fair bit of thought to try to figure out all the possible reasons for why this might fail, whereas seeing your setup would make that much easier). Please contact customer support - my guess is that you have something wrong with your UNIX paths (or have some wrappers in the way which are breaking things). In current versions you need both Spectre and XCELIUM in your path (the AMS Flex option takes care of this - we now use the analog solver from the spectre installation, whereas historically it was shipped along with INCISIVE). The same is true for the UNL netlisting - parts come from XCELIUM and parts from Spectre.

Andrew

Thanks Andrew. 

We don't have support for Xcelium product.  So we are at our own and your help  (with tight time constraints) is higly appreciated.

I understand about UNIX paths. But what is "some wrappers coming in the ways"  means here?

What are "assembler libraries in spectre installation" that AMS is looking for here ? I think I have given both the paths of XCELIUM and SPECTRE in the UNIX path.

1:-

We have installed :-  spectre location :- /P/cadence/installs/SPECTRE201/  --> MMSIM 

                                 Xcelium location :- /P/cadence/installs/XCELIUM2109/ -->AMSHOME 

                                 IC618 location :-  /P/cadence/installs/IC618/   --> CDS_INST_DIR

Accordingly,

corresponding enviornemnt variables and the paths given in the SET-UP cadence.cshrc file are as below:-

********************************************************************************************************************

#!/bin/csh

set filec

setenv CDS_INST_DIR /P/cadence/installs/IC618

setenv MMSIM /P/cadence/installs/SPECTRE201

setenv AMSHOME /P/cadence/installs/XCELIUM1903

setenv CDS_Netlisting_Mode "Analog"

set icpath=($CDS_INST_DIR/tools/bin $CDS_INST_DIR/tools/dfII/bin $CDS_INST_DIR/tools/dracula/bin)

set path=(. $icpath $path)

setenv LD_LIBRARY_PATH

set LD_LIBRARY_PATH=($CDS_INST_DIR/tools/lib $LD_LIBRARY_PATH)

setenv SPECTRE_FEATURE_FILE $MMSIM/tools/spectre/etc/files/spectre.dat

set path=($MMSIM/tools/spectre/bin $path)

The versions we are using are:-

I run AMS simulation (the testbench doesn't have any analog moduels it has only verilog blocks) as below:-

I'm sorry, but this makes no sense. You said in your previous post that you'd purchased XCELIUM - so you should have support. Please contact whoever you purchased it from.

Quick response though - and as I said, debugging this here is really not practical (and I don't have time to do so on the weekend), you don't appear to have any wrapper scripts around spectre, xrun etc and are running directly from the path.

I see you have MMSIM/tools/bin and MMSIM/tools/spectre/bin in your path - that's not really necessary. I'd just put MMSIM/bin in the path and nothing else. Also, do not set SPECTRE_FEATURE_FILE - this is only necessary if you have wrappers around the executables which prevents the automated mechanism from finding the feature file. It's only likely to cause you trouble if you set it yourself and it ends up at the wrong path for whatever reason.

Dear Andrew,

Thanks a lot. I removed SPECTRE_FEATURE_FILE  from my setup file and now it started to run properly.

My impression of no support for Xcelium product comes out of the fact that I could not find Xcelium in my product drop-down list while submitting the case in Online Support website. Anyway, we will contact Cadence University co-ordinator regarding this.

Again, thanks a lot for your help.

Kind Regards,
