Don't panic! Really! The tapeout should occur about now. AM will have reference chips by the end of February and are going to get back to all people interested when they have the chips tested and their actual specifications determined. Friedcat is committed to give an announcement before March and I'd be puzzled if this happens before about February 25th.
Wait for the actual final offer and you'll be fine.
I have to believe this is spot on. I've worked with a few ASIC companies and they either communicate well or not at all. Friedcat has a long history in this business, I anticipate communication from him or his team in the next few weeks.
