Celera acquires SiliconGate for analogue IC design
Celera Semiconductor has acquired Portugal-based SiliconGate, adding analogue IC design and supply capability as it expands its engineering presence in Lisbon and Porto.
SiliconGate specialises in analogue and power-management IC design services, with almost two decades of experience supporting customers across multiple application areas. Celera plans to develop the Portuguese operation into a centre of excellence for analogue design and delivery.
The acquisition also adds more than 900 silicon-proven IP designs to Celera’s analogue development base. In analogue and mixed-signal design, that kind of reuse has particular value because performance depends heavily on layout, parasitics, process variation, noise, matching, and temperature behaviour.
Patrick Brockett, CEO of Celera Semiconductor, said: “SiliconGate is a renowned supplier of power management design services. For nearly two decades they have provided these services to major customers worldwide for diverse applications.”
Celera is building its business around AI-assisted analogue IC design, using its Nesto technology to create digital twins of analogue functions. The company’s approach is intended to reduce development time and cost for standard and full-custom analogue products.
Analogue design remains one of the hardest areas of semiconductor engineering to automate. Digital logic can often be abstracted, synthesised, and verified through mature tool flows, but analogue circuits still rely on detailed understanding of device physics, process behaviour, and circuit layout. Offset, drift, distortion, electromagnetic coupling, and supply noise can all determine whether a design works once it reaches silicon.
The power-management element strengthens the industrial relevance of the deal. AI servers, electric vehicles, connected sensors, medical devices, factory automation, and battery-powered products all rely on efficient and stable power circuitry. Processor performance often dominates the headline discussion, but analogue and power ICs decide thermal behaviour, standby consumption, battery life, signal quality, and system reliability.
The acquisition sits within a wider design-automation shift across the semiconductor sector. Siemens’ AI-driven IC library characterisation and Cadence’s autonomous AI verification show how tool suppliers are applying more automation to work that has traditionally been slow, expert-led, and difficult to scale.
For analogue design, productivity gains are harder to extract because the design space is less discrete and the risks are more physical. Even so, the commercial pressure is growing. More companies want custom silicon, more products need power-optimised interfaces, and more system designs depend on analogue blocks that must be adapted quickly without sacrificing measured performance.
Portugal gains further visibility through the transaction as a location for semiconductor design talent. European chip strategy often concentrates on fabrication and packaging, but design capacity is equally important if more value is to remain inside the region. Lisbon and Porto give Celera access to engineering talent, university links, and a base for analogue development within Europe.
The deal does not make analogue design simple, but it points to a more repeatable model for delivering it. Combining silicon-proven IP, experienced design teams, and more automated development flows gives Celera a stronger platform in a part of the semiconductor market where expertise remains scarce and demand continues to rise.
