What is the estimated revenue for the gallium nitride segment of Cree in fiscal 2021
uawei carriers to start adopting gallium nitride in the rollout. Is that a qualification issue that's limiting that or are we just not in the capital deployment part of the 5G cycle there?
Gregg Lowe -- President, Chief Executive Officer, Director
I think Huawei has clearly been the most aggressive in terms of the adoption of gallium nitride and best we understand that they haven't done a non-GaN type new development in a number of years. So they've been really leaning forward on that. And other base station manufacturers are developing products with GaN but it was just at little bit slower pace.

Got it. And so is that -- if we looked out should we expect that for sort of fiscal 2021 type of time frame, again with the caveat that obviously things are fluid in the market, but is that sort of the timeframe that you're planning too there?
Gregg Lowe -- President, Chief Executive Officer, Director
Maybe, Jed, but what I would say is there is kind of another element of this whole story and that is the biggest market for 4 or 5G is likely going to be China. The biggest player is Huawei in that market and best we can tell from the data that's out there. The thought process that non-Huawei players who are going to pick up that business in China doesn't seem to have played out that way at least at this point. So I don't know exactly what that means and when that transition happens with other players picking a part of that, but at least at this point, it's been now 5.5 months since the entity list came on board and that doesn't seem to have happened?

Got it. That's helpful. Thanks. Just moving over to the silicon carbide, the Tesla solution uses one inverter module per motor. So where we in a car that has all-wheel drive, that's two motors. What we're seeing is designs that are different than that out of other EV manufacturers. Do you think that the market will standardize on sort of that Tesla design or do you think it'll be equally shared because obviously that's going to have a pretty big impact on the silicon carbide content if you potentially have two slots or two modules per vehicle versus one?
Gregg Lowe -- President, Chief Executive Officer, Director
We're working with number of different customers that have a variety of different architecture. Some of them have four modules placing one on each wheel. I think it's way too early to tell in the EV market what's going to be the standard or if there is even going to be a standard anytime soon. What I would tell you is the car manufacturers; the OEMs view the engine of the car is sort of the heart and soul of the car. And so they want to performance that they want. They want the soul of the car to become in sort of their image of what they want the driving conditions to be. So I would imagine there is going to continue to be a number of different architectures that are out there, we're engaged in, with most of the Tier 1s and the OEMs in discussions on what these architectures look like.
But what I'd also tell you is that the interest in silicon carbide for the inverter has gone from -- we're going to think about it to -- it's likely going to be the solution. So I feel very comfortable that the -- when you look at our design pipeline that -- about half of the $9 billion is related to automotive. I would say, the probability of that pipeline being decided as silicon carbide versus silicon is extremely high. And I would say, we're just working really hard to make it a Cree-based solution.

Hi, good evening and thanks for taking my questions. So Gregg, when we look at the big picture, right. Your $9 billion pipeline, the activity with customers, we can name like Delphi, Tesla, VW, Porsche. It's pretty easy to put together a longer-term picture, a longer-term growth story where we can have confidence in some fairly significant growt
