Synopsys Discontinues Chip Manufacturing Control Software, Pivots to AI Design
Miles Bennett
Synopsys is discontinuing EES and FDC — factory-floor software used by chipmakers worldwide — and redirecting engineering resources toward AI chip design, a move that redraws the division of labor across the semiconductor software industry.
What exactly is Synopsys dropping?
Between April and May, Synopsys sent "end-of-life" notices to more than ten chipmakers, including Samsung, SK Hynix, Kioxia, and Qorvo.
The affected products are EES — equipment engineering systems that monitor production-tool health in real time — and FDC — fault detection and classification software that flags manufacturing anomalies before defects spread.
This means → Synopsys will stop releasing new versions and only honor existing maintenance contracts. The software won't vanish overnight, but it stops evolving.
Why kill an entire product line?
Synopsys calls these "legacy diagnostic tools not on customers' critical production paths." But sources point to two deeper reasons.
Reason one: a data wall. Improving EES requires chipmakers to share highly sensitive production data. Customers like Samsung are already building in-house alternatives and no longer willing to open that data — eroding the product's competitiveness.
Reason two: a profit trade-off. Synopsys wants to shed support obligations and redeploy engineers to high-margin AI design. In plain terms = rather than grinding in a market where margins are thinning and customers are pulling away, the company is moving headcount to where growth is faster.
How much does this hurt chipmakers?
Sources disagree. Two say the discontinuation could dent yields at some fabs, because the software needs constant updates to keep pace with process changes.
Four others say major chipmakers' production will not be materially affected. Samsung confirmed it has compatible alternatives in place, stating there will be "no negative impact on production."
This reflects a broader trend: leading chipmakers are internalizing manufacturing-software capabilities, reducing dependence on outside vendors.
Where does Synopsys's AI play stand?
Synopsys only began offering EES after acquiring the semiconductor-manufacturing unit of South Korean firm BISTel in 2021 for an undisclosed sum. In 2025, it closed the $35 billion acquisition of engineering-software company Ansys.
In March this year, Synopsys unveiled technology it says will pave the way for AI agents to take over chip-design tasks.
This means → the strategic logic is clear: the acquired manufacturing software can be cut; the $35 billion engineering-simulation and AI-design stack is the main line. Resources are converging in one direction.
What does this tell us about the industry?
The division of labor in semiconductor software is being redrawn: vendors are concentrating investment on AI design tools, while chipmakers are accelerating the move to bring manufacturing software in-house.
In plain terms = chipmakers used to buy external software for both production control and design. Now the "production control" piece is increasingly built internally, while software vendors are doubling down on the "design" piece.
Synopsys has already laid off dozens of employees tied to these products — the most direct signal that resources are being reallocated.
