That's a good point Scott. Asynchronous clock domains are indeed complex and it took us time to manage them efficiently. When you need to connect different clock domains with Cx/ngDesign you have to synchronize the various tasks with specific components (e.g. SynchronizerMux) http://cx-lang.org/documentation/instantiation/stdlib. Simulating the interactions between the domains is not yet supported by our simulator. We will develop this feature when people will request it. And you know, we're a startup so we still have plenty of R&D to do :-)

I think if you can crack the modelling and simulation of asynchronous clock domains then I suspect you will have something that the other HLS solutions don't have at the moment that would be an incredibly useful feature. Design with async clocks is difficult and I have seen loads of bugs with these interfaces (including bugs found in the field for chips that were release many years previously).
