I am a heavy user of Xilinx system generator too. So far I found it very useful
in developing DSP intensive applications such as wireless baseband modems. In
fact, recently I came across another method of developing DSP systems for FPGA
using simulink which is exceldsp. It helps in converting Simulink floating point
models into fixed point model and then use system generator for building the
fixed point model for target FPGA.
I found one interesting article for Chris Dick about building synchronizer for
QAM using these tools in 30 min!!
I'm curious as to what the general attitude of the community towards
various Simulink/FPGA DSP tools is.

development time on even all logic (non-DSP) based designs. In fact, I cringe
at the thought of ever hand-writing VHDL for any reason, after the ease of
development in XSG.
