Synopsys, one of the most powerful companies in the semiconductor industry, is pulling the plug on software that chipmakers worldwide use to keep their factories running cleanly, and redirecting those engineers toward AI design tools where the money is better.

The move, reported by Reuters and confirmed by six sources briefed on the matter, affects products called Equipment Engineering System and Fault Detection and Classification. Those names are technical, but the function is not: this is the software that watches semiconductor fabrication plants in real time, spots problems before they cascade into ruined batches of chips, and triggers corrections before yields drop. Think of it as the monitoring layer that keeps an enormously expensive, impossibly precise manufacturing process from going sideways.

Synopsys notified more than ten chipmakers about the "end of life" decision in April and May. Samsung Electronics, SK Hynix, Kioxia, and Qorvo are among those affected.

Why Synopsys is walking away

The short version: the margins weren't there, and the strategic direction changed.

Synopsys completed a $35 billion acquisition of engineering software firm Ansys in 2025, a deal that pushed it firmly into high-value design and simulation software. The company has also been moving aggressively into AI-assisted chip design. In March it introduced technology it said would allow AI agents to take over many tasks in the chip creation process.

Against that backdrop, maintaining an older suite of manufacturing analytics tools looked like a drain. Keeping the software competitive also required chipmakers to share tightly guarded manufacturing data, which many were reluctant to do. Samsung, according to two sources, had been building its own in-house version anyway, which was quietly eroding the commercial logic of Synopsys staying in the game. The company has already laid off a few dozen staff tied to these products.

What this means in practice

Synopsys says it is honoring all existing support and maintenance obligations through the transition, and plans to conclude talks with each chipmaker on those obligations by July. It described the tools as "older diagnostic tools not in our customers' critical paths of production."

Samsung's own spokesperson backed that framing, saying alternatives were in place and there would be "no negative impact on production."

Two sources told Reuters a different story, however. They said the software requires constant updates and patches to stay effective, and removing it creates some risk of declining production yields. Yields, in chipmaking, measure what share of chips produced actually meet quality standards. Even a small drop in yield across a leading-edge fabrication plant can mean hundreds of millions of dollars in wasted material and lost output.

Four other sources said they did not expect a production impact at major chipmakers. So the risk is real but contested, and the biggest players appear to have time to prepare.

The bigger pattern

This is what the AI investment wave looks like from inside an industry. Companies like Synopsys are not cutting these products because the factory floor stopped mattering. They are cutting them because capital and engineers are expensive, AI design tools command far higher prices and margins, and the market rewards the companies that move first.

The semiconductor software industry is quietly restructuring around that logic. Vendors are pushing up the stack toward design and simulation, where AI creates genuine leverage. The manufacturing layer, closer to the physical messiness of actual production, is increasingly something chipmakers are being pushed to own themselves.

For Samsung, SK Hynix, and others, that means more internal engineering investment in tools they used to buy. For Synopsys, it means a cleaner, higher-margin product line and a sharper bet that AI design is where the next decade of semiconductor value gets made. Whether that bet pays off depends partly on whether the companies walking away from the factory floor are right that someone else will handle it just as well.
