SiliconGate

SiliconGate is a Portuguese semiconductor intellectual-property (IP) company based in Porto, founded in 2008. It develops and supplies silicon-proven IP cores for ASIC and SoC designs, with a particular focus on power management. Its portfolio has grown to more than 800 IPs covering linear power products such as voltage and current references, advanced power controllers and POR monitors, LDOs, LED drivers and battery chargers. The company positions itself as a mixed-signal design partner, combining in-house expertise that ranges from full-custom design to top-level architecture definition. SiliconGate's team includes engineers with more than 50 years of combined experience, and some key members have over 20 years of experience; they were founders of the power-management team at Chipidea in 2000, where they created several innovative products for different applications. This heritage underpins SiliconGate's claim to be a trusted partner for the development and manufacture of successful power-management products. The company states that its IP solutions address the main power-management challenges faced by designers, including circuit efficiency, total consumption, silicon area, system verification and time-to-market. Beyond IP cores, SiliconGate provides specification review, design, integration and characterisation services. Its design process follows design-for-manufacturability (DFM) and design-for-testability (DFT) best practices, and its integration services can deliver IP cores separately with a Verilog netlist or integrated into a single PMU IP that may include ESDs and bumps/pads. Detailed characterisation is described as mandatory to ensure quality and support. SiliconGate serves the global semiconductor market. In recent news, Celera Semiconductor acquired the Portugal-based company, described as a global leader in analog IC design. SiliconGate also announced it would host the next GreenChips-EDU Consortium Meeting in Lisbon in April 2025. The company's activities are co-financed by public or institutional programmes, and it presents itself as committed to customer success since 2008.

SiliconGate was established in 2008 in Portugal, with its base in Porto. From the outset it focused on the development and supply of intellectual property (IP) for ASIC and SoC designs in the field of power management. The founding team brought deep domain experience: some key members have over 20 years of experience and were the founders of the power-management team at Chipidea in 2000, where they created several innovative products for different applications. This background shaped SiliconGate's approach of combining experience and innovation to deliver high-quality solutions for the global semiconductor market. Over the years the company built an extensive IP portfolio that grew to more than 800 IPs, offering a broad range of power-management solutions for diverse markets and applications. Its IP solutions are designed to address the main power-management challenges faced by designers, such as circuit efficiency, total consumption, silicon area occupied, system verification and time-to-market. The portfolio includes linear power products such as voltage and current references, advanced power controllers and POR monitors, LDOs, LED drivers and battery chargers. Examples include the SGC75 family of capless low-dropout regulator IP and the SGC77 family of low-dropout regulator IP, both designed for integration on SoC. Alongside its IP cores, SiliconGate developed a services business covering specification review, design, integration and characterisation. The company states that its design process is robust and follows design-for-manufacturability (DFM) and design-for-testability (DFT) best practices, and that its engineers have extensive experience ensuring correct functionality from the Verilog model to the final design. Integration services allow IP cores to be provided separately with a Verilog netlist or integrated into a single PMU IP that may include ESDs and bumps/pads, and detailed characterisation is described as mandatory to ensure quality and support. A significant recent development is the acquisition of SiliconGate by Celera Semiconductor. The company's own news feed announced: "Celera Semiconductor Acquires Portugal-Based SiliconGate, a Global Leader in Analog IC Design." SiliconGate also announced that it would host the next GreenChips-EDU Consortium Meeting in Lisbon in April 2025, indicating continued engagement with collaborative research and education initiatives. Its activities are co-financed by institutional programmes. As of the available evidence, SiliconGate remains active and continues to serve the global semiconductor market from Portugal.
