Matt, you may just be the PR person, and if so then it is possible that you did not know the situation.  But if tape out should have happened 2 months ago in order to have chips done by the end of Feb, (which would be the same deadline that you are on now), and it obviously didn't happen, then it should have been known for the last 2 months that the chip would not be ready in time.  So every single "update" that has been given saying we are on schedule or slightly ahead of schedule, where was that information coming from?  Someone was/is lying, now that may not have been you, if that was the information you were given, but regardless your the spokesperson for this organization, and like it or not, your customers are cumulatively losing hundreds of thousands of dollars of losses due to late shipment.  So who has been lying and saying things were on schedule?  That should be the first question answered!
