“Vcs and that's how how we started now on the technological side ah up until that time and all the chip sets that were designed were only up to five six gigahertz so any fab that manufactures the chips will give you models up to 10 gigahertz and that's what you use to model your design and simulate simulate your design we needed Sixty Gigahertz so there were no models. So the favs didn't have models. So. We had to basically build our own models. So we we'll just fabricate a chip that was lines and very basic structures that then we had to measure and build the models so there was a lot of. I would say r and d in order to to get there.”
