Absturz nach Extractor-Start (Cadence)

Liebe Cadence-Spezialisten,

wir verwenden an unserem Institut Cadence (5.0.32) auf Linux
Redhat-Basis (Enterprise WS3). Cadence wird mit einem Kit von X-Fab
(Melexis) gestartet.

Der Schaltungs-Editor, der Simulator, der Layout-Editor und der
DRC scheinen zu funktionieren. Aber wenn der Extractor gestartet wird,
kommt es zu einer Speicherschutzverletzung und Cadence wird beendet.
Vor dem Absturz wird noch "\w *WARNING* Errors exist in rules file so
this program cannot continue." in die Datei cds.log geschrieben.

Der Absturz ist vom Layout unabhängig. Selbst bei einem Layout, dass
nur aus einem Element der PRIMLIB (z.B. ein QNB2) und einem
Substrat-Kontakt besteht, stürzt Cadence beim Start des Extractors ab.
An der Stelle, an der normalerweise "\o Running layout Extraction
analysis" stehen sollte, steht 10mal:

"\o error: vcPropagateChange failed to update task. Notify Cadence.."

und dann:

"\w *WARNING* Errors exist in rules file so this program cannot
continue."

Danach stürzt CADENCE ab.

CADENCE-Version: 5.0.32.61
LINUX-Version: Red Hat Enterprise Linux WS3

Im Voraus herzlichen Dank für jede Hilfe.

I don't know German (I think that's what this is), but I do recognize
the error message "vcPropagateChange failed to update task. Notify
Cadence". This error has to do with calculateParameter and
calculateParasitic with an expression involving one variable and no
operands. The error was fixed about a year ago. 5.0.32 is no longer
supported and you should get a 5.0.33 or 5.1.41 release installed.

In the meantime, you can get around the problem by modifying the rule
deck. Where you see a rule of the form:

y = calculateParameter(x)

change it to:

y = calculateParameter(x * 1.0)

 

Hallo,

das Problem koennte Design-Kit abhaengig sein.
Was sagt denn X-Fab zu dem Problem?

Gruss Bernd

 

Josef,

If you don t like the background noise of warnings and errors, you could also set the environment
LD_ASSUME_KERNEL=2.4.1 ; export LD_ASSUME_KERNEL
and use the command line option "-use24" to start the workbench.

And now, the french version :

Si tu es derange par le bruit de fond des avertissements et erreurs, tu pourrais aussi assigner la variable d'environnement
LD_ASSUME_KERNEL=2.4.1 ; export LD_ASSUME_KERNEL
et utiliser l option de ligne de commande "-use24"


I propose we adopt on comp.cad.cadence the language conventions used in Brussels for the EU , OK ? ;-)
