What Extoll does

Extoll GmbH is a Mannheim, Germany-based semiconductor intellectual property (IP) company founded in 2011 that designs high-speed interconnect building blocks for chiplet-based silicon systems. Its product portfolio comprises three core IP families: SerDes (serializer/deserializer) for inter-chip communication, UCIe (Universal Chiplet Interconnect Express) for heterogeneous chiplet integration, and NOC (Network-on-Chip) for on-chip multi-core communication. The company employs a digital-centric architecture targeting mainstream 12-28nm process nodes to achieve ultra-low power consumption and cost efficiency versus advanced-node alternatives.

The company serves fabless chip designers and semiconductor manufacturers seeking proven, production-ready interconnect IP for chiplet-based designs. Its technology is positioned to enable heterogeneous integration and modular semiconductor architectures in markets including high-performance computing and data centers. In 2024, Extoll and Chip Interfaces introduced the industry's first integrated UCIe IP solution qualified for GlobalFoundries FDX (FD-SOI) technology, marking a process-node and ecosystem expansion.

Extoll monetizes through B2B IP licensing under royalty-based agreements, distributing directly to enterprise customers via a sales-led motion centered on technical partnerships and direct engineering engagement. Pricing is quote-based and not publicly disclosed. The firm remains privately held with a single disclosed institutional funding event (a 2012 seed from High-Tech Gründerfonds), no public financials, and a workforce in the 11-50 range. Operating geographies are concentrated in Europe, though its IP licensing model and global semiconductor customer base imply distribution beyond the headquarters region.

Core offering

Extoll (EXTOLL GmbH) designs and licenses semiconductor intellectual property (IP) cores focused on high-speed interconnect for advanced chip-to-chip and chiplet-to-chiplet communication. Its portfolio includes SerDes IP, UCIe (Universal Chiplet Interconnect Express) IP, and Network-on-Chip (NOC) technology, all built on a digital-centric, ultra-low power architecture that enables deployment on mainstream process nodes without requiring exotic technology.

Product overview

EXTOLL is a semiconductor IP company offering a portfolio of three core interconnect products: SerDes, UCIe, and NOC. These products serve as the building blocks for chiplet-based technology, enabling customers to create systems using mainstream tech nodes (12-28nm) that are faster, super energy efficient, and more scalable than ever before. The company's unique digital-centric architecture empowers SerDes interconnects and UCIe solutions for systems applying chiplets in heterogeneous integration.

• Chip InterfacesflagshipTechnology or IntegrationEXTOLL and Chip Interfaces formed a strategic partnership to develop and launch the industry's first UCIe IP solution for GlobalFoundries FDX Technology. This collaboration integrates EXTOLL's high-speed interconnect IP with Chip Interfaces' chiplet interface technology to deliver a complete UCIe solution optimized for GlobalFoundries' FDX (Fully Depleted) semiconductor process technology.

Scale indicators1 record

Recent moves3 records

Expansion highlights4 records

Broad incumbents

• Synopsys: Synopsys is the dominant EDA and semiconductor IP vendor offering DesignWare SerDes, UCIe, and NoC IP alongside full EDA toolchains. It competes with EXTOLL in chiplet interconnect IP but operates at vastly greater scale with bundled design flows and global foundry relationships.
• Cadence Design Systems: Cadence offers a broad IP portfolio including SerDes, memory, and interconnect IP used by similar fabless and foundry customers as EXTOLL. Its strength in EDA tools and integrated design environments makes it a one-stop alternative to EXTOLL's specialized interconnect offering.
• Rambus: Rambus licenses high-speed interface IP (SerDes, memory, security) to chipmakers and overlaps with EXTOLL's SerDes and chiplet interconnect offerings. It is a much larger IP licensor with established revenue and global customer support.

Direct peers

• Alphawave Semi: Alphawave is a leading pure-play high-speed SerDes and UCIe IP company serving hyperscalers and chiplet designers. It is the closest direct peer to EXTOLL in business model (IP licensing), product category (SerDes/UCIe), and target customer base.
• Arteris: Arteris is a dedicated Network-on-Chip IP vendor serving chip designers with interconnect IP, directly overlapping EXTOLL's NOC product line. Both companies license IP to fabless designers and system-on-chip developers, with similar revenue model and customer profile.
• Chip Interfaces: Chip Interfaces is EXTOLL's flagship partner and also offers chiplet interface IP; their collaboration on the first UCIe IP for GlobalFoundries FDX places them as both collaborator and competitor in the chiplet interconnect IP market.

Emerging players

• Astera Labs: Astera Labs develops connectivity and compute silicon for cloud and AI infrastructure, and has expanded into UCIe-based chiplet interconnect solutions. It overlaps with EXTOLL's HPC/data center customer focus and chiplet interconnect technology area.
• Eliyan (previously known as AlphaICs): Eliyan is developing die-to-die (D2D) interconnect PHY IP and chiplet solutions competing in the same UCIe/chiplet connectivity space as EXTOLL. It serves similar hyperscaler and HPC customers with comparable chiplet-focused IP positioning.

Others

• GlobalFoundries: GlobalFoundries is the foundry partner for EXTOLL's UCIe FDX reference design, providing process technology and validation but not IP. It is a customer/enabler in the ecosystem rather than a direct competitor, though GFx also offers certain IP partner programs.
• Agnisys: Agnisys provides EDA tools for IP and SoC design specification and verification, an enabling technology adjacent to semiconductor IP vendors like EXTOLL. While not a direct competitor, it serves the same fabless and ASIC design customers.
