We have a fairly straightforward build process (makefiles, and TCL)
for our Xilinx FPGAs using non-project mode TCL.  We do nightly builds
on all our FPGAs - the current build list is ~40 FPGAs.

For Xilinx IP we struggle up front to use the F#@#$F IP integrator or
other GUIs to generate an example project.  Then we reverse engineer the
RTL that's usually under the covers, and use that directly.  Everything
else is thrown out.  We've typed up a "Just the RTL" document which
we've given to Xilinx to explain why we do this. 

After the time spent on the up-front reverse engineering, things work fine -
never having to open the darned Xilinx IDE again.

This thread gives make me nod my head (in a misery-loves-company sort of
way) in that I see you software folks are basically doing the same
thing.  

The absolute WORST part of the Xilinx flows is in their MPSoC designs
and configuring boot-loaders and rootfs images.  Here one must use their
awful 80s style schematic capture code to configure the bootloader, and
initial images.  Yes, schematic capture to design software.

They even crypto-sign the intermediate files (HDF) to prevent engineers from 
trying to create a more sane flow.  Absolute insanity...
