spp is not working

marklin

I need to convert from spice model to spectre model.    When I type spp,  I got   

/cadence/cds/IC5141-usr6/tools/lib/libgcc_s.so.1: version `GCC_3.3' not found (required by /usr/lib/libstdc++.so.5)

When I check the libgcc_s.so.1 in either /lib  or /cadence/cds/IC5141-usr6/tools/lib, 

strings /cadence/cds/IC5141-usr6/tools/lib/libgcc_s.so.1 | grep "GCC"    comes up   GCC_3.0

strings  /lib/libgcc_s.so.1 | grep "GCC"  comes up

GCC_3.0
GCC_3.3
GCC_3.3.1
GCC_3.4
GCC_3.4.2
GCC_4.0.0
GCC_4.2.0

Why spp has to use /cadence/cds/IC5141-usr6/tools/lib/libgcc_s.so.1 instead of /lib/libgcc_s.so.1?

Thanks.

    You should not use spp - it's been obsolete for 11 years now and has not been maintained. It is not in any current release (IC5141 was the last release it was in, and that came out in 2004).

    Spectre can natively read SPICE netlists (more reliably than spp can convert them). Whilst spectre has always had some level of SPICE syntax support, a new native front end was added in spectre in (I think) the IC5141 version, but it wasn't enabled by default (you had to turn it on). However, you shouldn't be using spectre from the IC5141 stream anyway, because in late 2004 spectre was moved into the separate MMSIM stream. There have been 12 major releases  of MMSIM since then (the latest being MMSIM15.1) and so you should be using spectre from a recent MMSIM stream, even if you are stuck with IC5141 for some reason.

    So this would make your question a moot point. I suspect you're having a problem because you are running on an unsupported OS, but avoiding using spp altogether would be the best solution.

    Regards,

    Andrew.
