Can you tell us what the sticking point is? Is it integrated but not working, or is the problem knowing how to get it connected, configured and synthesised?
We will definitely look at your cores, we would very much like to build ecosystem. We have some thoughts on that... Geoff's SoC top level generator tool is proof that a high level of automation is both possible and useful...
