Trying to use Designware compiler to build for altera FPGAs.
Quartus II supplies the needed db files, however it doesn't seem to be consistent! I can't make any small designs, but I have successfully built a large AMBA structure for a cyclone II. Trouble is the libraries are rated as compatible with designware compiler 2004, not 2007.
The compiler dies with an internal error and a stack-dump. Will try driving design compiler by hand first to get more design information.
