I also suffer from this but I have found the following at least reduces it
1. copy the EDK make file (i.e "yourprojname".make) giving it a new name (keep it in the same dir)
2. edit the make file copy and change the lines
@xflow -wd implementation -p $(DEVICE) -implement xflow.opt $(SYSTEM).ngc
and
@cd implementation; bitgen -w -f bitgen.ut $(SYSTEM)
to
@xflow -wd implementation -p $(DEVICE) -implement xflow.opt $(SYSTEM).ngc >> $(SYSTEM)_build.log
@cd implementation; bitgen -w -f bitgen.ut $(SYSTEM) >> $(SYSTEM)_build.log
after the lines
@echo "*********************************************"
@echo "Running Xilinx Implementation tools.."
@echo "*********************************************"
@cp -f $(UCF_FILE) implementation/$(SYSTEM).ucf
add
@rm -f $(SYSTEM)_build.log
3. In the EDK GUI under Project/project options set the edited make as the custom make file to use.
The effect of this is to redirect the log output from the build to a file and not into the EDK gui transcript window. The dissadvantage
is you now can't see the build progress (open the log file "$(SYSTEM)_build.log" in a "good" editior to follow it) and if
you do changes to the proj i.e. add a new Proj software app the make file will be out of date (i.e. you have to do the above again using the EDK generated make file, I supose it is possible to write a make the edits the EDK generated make etc... but thats a lot of work)
Overall its better then having the build crash 2 hours into the build and having to re-do/re_do.....
I also seen the fatal crash during sim gen so the method may also work on the make files sim gen sections but I've not tried that.
