THE ANALOG CHIP DESIGN CHALLENGE
While much of the microchip design process is automated, the most critical parts of modern chips are still hand-crafted by engineers.
Believe it or not, today circuit designers manually place a single transistor at a time, guided only by decades of experience and an intuitive understanding of physics.
This line of work is called Analog Design.
And it's also the biggest bottleneck holding back the next generation of computing.

As transistors shrink and frequencies rise, idealized 1s and 0s blur into analog behavior.
At the cutting edge, physics can't be ignored.

Analog design is the art of mastering this physics, squeezing out every ounce of performance.
It can deliver 10× gains in speed or power.
But only through human craft, not automation.

In practice, engineers place 5 to 20 transistors in a single layout — yet even for this seemingly small layout, there are more configurations than there are atoms in the universe.

Our first focus: the analog circuits behind high-speed SERDES, the links that move data between chips at 224 Gbps and beyond.
They’re the backbone of AI-scale compute, enabling GPUs to communicate at massive bandwidths across data centers.
And yet, almost entirely designed by hand.

We’ve adapted the core ideas behind AlphaGo and applied them to physics-aware chip design.
Our system learns through self-play, generating trillions of designs while developing the intuition behind what makes a circuit exceptional.
Like AlphaGo, Astrus combines reinforcement learning, deep learning, and search to master layout from first principles, not by copying humans.

Astrus is developed hand-in-hand with some of the top analog designers in the world.
Our in-house experts have taped out high-speed circuits on bleeding-edge nodes.
We also work closely with design partners, many of whom give real-time feedback, often just a call away.
This collaboration ensures Astrus is grounded in the realities of advanced analog layout, and designed for serious designers who know what great looks like.
