SAN JOSE – Cadence Design Systems has acquired EMA Design Automation, its key distributor in the printed circuit board software design space, according to an announcement the ECAD software giant sent to the latter’s customers and users today.

Financial terms of the acquisition have not been disclosed; however, Cadence said it would retain all EMA’s staff.

The deal culminates a long relationship between the two companies.

Since 2003, EMA Design Automation has for years been exclusive distributor of Cadence’s OrCad products in North America and Europe. In 2011, EMA added the Allegro PCB flow to its line card, further tying the company’s outlook to its key partner. 

A value-added reseller, EMA has made several acquisitions over the years to expand its products and reach. Among its acquisitions were DesignAdvance in 2009 and Accelerated Designs in 2016, which added component placement, reuse and library tools.

In late 2020, EMA brought on the engineering sales and support team, Trilogic EDA, a fellow VAR.

In 2023, EMA spun out its CAD-agnostic products into a standalone company. The deal with Cadence includes all stock, assets and its 76 employees, including the EMA subsidiaries.

The move comes at an interesting time for Cadence. The company has grown rapidly in the silicon design space, and system design and analysis – which includes the PCB tools – made up close to $850 million of its $5.3 billion in sales in 2025. 

Given that growth, as Cadence’s exclusive distributor in North America and Europe, EMA likely had other suitors, but the former’s control of the IP likely proved a thorny issue to potential buyers.

The mainstream market remains a fascinating work in progress. The larger EDA vendors have time and again tried to consolidate their PCB products into a single flow, only to have customers push back for reasons of familiarity and price, among others.

As such, legacy tools such as OrCAD, Pads (Siemens) and CadStar (Zuken) remain commonplace even while the higher-end software development pushes technical boundaries.

Concurrently, Renesas’ acquisition of Altium has left it disadvantaged to landing US government customers, and no EDA supplier has the mainstream field application engineering expertise on a par with EMA’s.

Still, the deal raises many questions, not the least of which is, what will tool development look like going forward? Among the assets are two tools from FlowCAD and three or four from EMA. These products fill certain gaps in Cadence’s line card, but will the OEM simply maintain them to milk out whatever cash it can, or will it continue EMA’s legacy of investment and enhancement?

Likewise, EMA’s Ultra Librarian library tools are used by thousands of designers worldwide. Fundamental to its model is its vendor-agnostic strategy. Can Cadence resist the urge to fiddle?

If Cadence can retain EMA’s staff and – more importantly – its customer-centric culture, this could be a real win. If it follows the near-term profits rather than investing in its newest toy, however, the cost will be felt by users worldwide.

And if that happens, Cadence might find lots of smaller players will be more than happy to pick up the slack.
