ATM - Which is also a dead technology BTW. ,-)

Trust me, I have used basically basically all tools available on the market
for SoC-modelling (they generally suck pretty badly) and been involved in
writing a few proprietary models and tools myself.
I'm also aware that there are places where SystemC is used. What I refer to is
that among peers (according to stats from DAC, comments in ESNUG etc), SystemC
is not popular. And even more importantly among peers, SystemC doesn't seem to
solve problems in a way more productive way that people are doing today.
What have also become quite clear is that many sites that have been using or
are using SystemC are doing so because high-level management have decided on
using SystemC, not because the engineering department have asked for it.
I have also been on presentations by EDA vendors where the argument *for*
SystemC have been that by using SystemC, "cheap SW designers" (as in low
salaries) can build ASICs. That have been the argument and some managers are
buying in to that.
It's a similar to the argument used by some to promote graphical design entry
tools, where knowledge about hardware somehow is not needed when you can draw
FSMs, flowcharts etc.
