Everything you need to achieve first-time-right​

Design Support

As a company dedicated to offering its customers first-class service and support, X-FAB boasts the most comprehensive design support in the whole foundry business. Our main objective is to enable a first-time right not only for digital, but also for analog mixed-signal designs. To achieve this, we offer a full-fledged design support for all major electronic design automation (EDA) platforms, supplying correct models, process design kits (PDK) as well as analog and digital libraries.

Our unique hotline service is available 24 hours a day to answer any enquiry you might have, while our online customer portal My X-FAB provides fast and efficient access to online technical information.
For additional support services such as design service, test/assembly or turn-key solutions, we work together with a range of partner companies. Find out more about these partners here: X-CHAIN.

The customer’s view is the real proof of the quality of our work. I am proud, that our technical support is constantly rated above the industry benchmarks. We have received very positive feedback and dedicate our daily work to make it easier for our customers to develop chips successfully.

EDA tools and partners

The design of an analog/mixed-signal IC is a very complex task that is heavily dependent on a powerful environment for electronic design automation (EDA). We are working constantly to improve the design flow based on commercially available tools and, when we identify a gap, to develop our own tools to overcome occurring obstacles.

X-FAB maintains intense and close collaboration with all major EDA providers in order to develop design kits together with them. To address specific problems, we complement the design flow with dedicated tools from other vendors. 

Process design kits

We support all major EDA vendors with feature-rich process design kits (PDKs) which contain all data to work with the digital, analog and mixed-signal design-flows in combination with our foundry data.Through our customer portal My X-FAB you have the shortest path from download to design.

We ensure interoperability

Our philosophy for the PDKs is to ensure interoperability by generating the same results irrespective of the chosen tool. This gives designers the free choice to select the best tool suite or to migrate between EDA vendors.  

Pre-defined setups in My X-FAB's SpecXplorer

You will find pre-defined setups for various EDA tools based on the recommended setup by the vendors. After selecting the required modules in SpecXplorer your design kit is automatically configured.

Advanced PDK features

Analog/mixed-signal designs are becoming more complex consisting of sensors, analog and digital circuitry including RAM, ROM and NVM and feature high voltage transistors side by side with low noise amplifiers. Especially the design of complex systems for automotive, industrial and medical applications require effective tools and techniques to achieve robust designs. We support you with advanced features included in our PDK to meet design goals, to achieve good yield and product reliability.

Expert support

An important element of our design support is the direct expert to expert interaction with of you, our customer. 

  • Technical hotline

    Your first contact is our Technical Hotline, where our qualified team provides you with an answer whether you have a question concerning design kits, libraries, IPs, process specifications, or safe operating areas. Drawing from their own expertise as well as working closely with Field Application Engineers and our in-house experts, they will answer your inquiry 24 hours a day, 5 days a week.

  • ESD support

    Developing integrated circuits which can withstand ESD (Electrostatic discharge) is a design challenge. Many of the devices we manufacture are deployed in harsh environments fulfilling safety critical sometimes life sustaining functions. To help you mastering this challenge we offer special ESD consultation and ESD Design Review as part of our design service. As ESD has to considered in all stages of a design, you can contact our ESD experts during the full development process.

  • Reference kits

    Besides the comprehensive collection of our technical documentation and application notes on our customer portal myXFAB, we provide reference kits to enable a fast and easy adoption of state-of-the-art design flows. Our X-FAB Reference kits address focus areas like analog/mixed-signal, low power, multi voltage, or RF using real life design examples. The kits demonstrate advanced features of our PDKs and IPs and are available for all major EDA vendors (Cadence, Synopsys, Siemens EDA) including special purpose tools from Muneda and Silicon Frontline.


Reusing proven circuit IP is essential for first-time-right designs and fast time to market product development. We offer a broad range of proven IP, used and validated in 100s of customer designs. All our IP is developed In-house by our design teams for best compatibility and support state-of-the-art implementation flows like multi-voltage domains and partial power-shutoff.

  • We provide dedicated I/O cell libraries for pad-limited or core-limited designs respectively, where all I/O structures have been characterized for ESD protection and latch-up resistance. The libraries contain distinct and complete input, output, bidirectional and general-purpose analog I/O cells. Special high voltage I/O libraries support voltages up to 61V and ESD level 2kV-8kV HBM.

    Standard Digital I/O Libraries

    • Bulk CMOS and SOI based I/O cell libraries are available for pad-limited or core-limited designs
    • The I/O structure has been characterized for ESD protection and latch-up resistance
    • Cell library contains distinct and complete inputs, outputs, bidirectionals, general purpose analog I/O and supply cells

    Special I/O Libraries

    • Latch-up robust pad cells for HV supply and HV I/O protection
    • SCR based clamp circuits with high ESD robustness and low or high holding voltage for HV I/O protection
    • HV I/O with reverse voltage protection

    Comprehensive technology specific ESD – I/O documentation

    • TLP IV Characteristics (Standard TLP, vf-TLP, LD-TLP, HMM)
    • ESD LU guidelines
    • IO and HV library documentation
  • For a quick start of your design we offer a broad spectrum of analog IP that not only allows you to focus on the core functionality of your product. To save a lot of design effort on your side and also reduce the risk of redesigns caused by non-functioning standard circuits our analog libraries consist of the full design database, e.g. for band gaps, bias cells, or voltage regulators.
