A battle is brewing in an under-followed part of the artificial intelligence (AI) industry: chip design software. Several merger and acquisition deals have been announced, and a mega-merger is pending between electronic design automation (EDA) leader Synopsys (SNPS 0.50%) and Ansys (ANSS -1.00%). Shortly after that was announced, the second EDA software suite, Cadence Design Systems (CDNS -0.32%), revealed its new supercomputing platform for simulating electronic systems.

Not wanting to get left behind, Japanese chip manufacturer Renesas (RNECY) announced its intention to acquire smaller EDA software provider Altium (ALMF.F -1.88%). Is something big brewing in the AI market?

Renesas looks for a software boost

Renesas is an integrated device manufacturer, a company that both designs and manufactures semiconductors. It's a hybrid business model that has been making a comeback in recent years. Besides Japan emerging as a top destination for manufacturing in the East, Renesas can thank the electric vehicle (EV) revolution for its resurgence, as well as a myriad of other more mature manufacturing processes (not leading-edge chips for things like data center AI) for chips in industrial and power applications.

Among some other smaller acquisitions to bolster its power chip portfolio, I wrote last year about Renesas' deal with Wolfspeed (WOLF 4.95%) to purchase silicon carbide (SiC) wafers for use in next-gen applications like EV motors.

But the purchase of Altium, a small competitor to the EDA software giants Synopsys and Cadence, is something else entirely. Tiny Australia-based Altium (which, notably, counts Wolfspeed as a chip design customer) generated revenue of just $139 million in U.S. dollars in the first half of its current 2024 fiscal year. And yet Renesas will be shelling out A$9.1 billion ($6 billion in U.S. dollars, using exchange rates on April 5, 2024). That's a hefty price premium.

Renesas' stated rationale is to boost the software and digital tool capabilities it offers its clients, as many of those customers (automakers, for example) are non-techies who may need help implementing next-gen electronics.

A big wave of AI coming?

As of right now, Nvidia's (NVDA -0.26%) data center AI systems are all the rage as companies are looking to use their data to "train" new AI systems. But in the decade to follow, all of those AI systems will need to go somewhere in order for users to benefit from their creation.

That's likely where Renesas sees massive opportunity by purchasing Altium, and competing with Synopsys and Cadence in electronics system design. Semiconductor manufacturing companies have a pathway to sustained growth thanks to customer interest in embedding intelligent computing systems across a broad ecosystem of devices, from cars to automated factory equipment to smart home devices.

All that new AI embedded in devices themselves, rather than housed in data centers, is going to need far more sophisticated hardware. It's also going to need more energy-efficient hardware, like the type Renesas has been working on (again, with the Wolfspeed deal). Renesas could secure itself a seat at the table for years to come by combining not just the chips, but also the software, to make those AI devices a reality.

Renesas could be a hidden growth stock in the AI race. Shares trade for about 13 times trailing 12-month earnings and free cash flow, a potential bargain if it can keep building a head of steam in its semiconductor manufacturing and design business for autos, industrial equipment, and consumer electronics.
