error when launching cadence IC610

Sindy

 Hi everyone,

 I just installed IC610 on our Linux machine (radhat enterprise5, 64bit) . We have a IC5141 on it already by the way. I got error when I tried to run the IC610. I put "virtuoso" and error information comes:

/cadence/IC610/tools/dfII/32bit/virtuoso: symbol lookup error: /cadence/IC610/tools/QT/lib/libQTGui.so.4: undefined symbol: XRenderFindStandardFormat

 Does anyone know how to solve this?

Thanks a lot!

    Just because you're running on a 64 bit machine doesn't mean you have to run the 64-bit versions of the executables. The 32 bit versions will run perfectly well on 64 bit hardware (in fact there's a small performance penalty with running the 64-bit versions, because the memory usage is greater as all pointers become 8 bytes rather than 4 bytes, so the memory access takes longer). So you only need to use 64 bit mode if your designs have capacity limitations (i.e. the executable needs more than about 3.7Gbytes of memory).

    The error about  libQtAssistantClient.so.4 is very odd - this should be found in the tools/QT/lib/64bit dir in the installation (and also in the tools/QT/lib dir for 32 bit).

    Something sounds very wrong here. You seem to be getting very peculiar failures which do not match what we've seen anywhere else. 

    You should contact Customer Support (or contact Cadence through your normal support channel if you're a university) - as it's going to be very hard to diagnose this in a community forum.

    Regards,

    Andrew.
