We are specialized in the field of low power mixed signal IC design down to 40nm gate length. Our core competencies include concept and design of integrated low power mixed signal circuits, layout-support and pre- as well as post- silicon verification.
Concept engineering: The performance of a microchip in terms of functionally, reliability and production cost is mainly defined in the concept phase. First of all we understand the application and functionality of the chip to be developed. Then we find the most efficient architecture by high level system modelling and simulation. Additionally patent drafts are as well as a detailed architecture specification are generated.
Circuit design: We are specialized in mixed signal circuit design down to 40nm by using Cadence Virtuoso and hardware description languages like VHDL or Verilog. Circuit design includes all steps necessary for creating a circuit hierarchy implementing the concept previously defined. Additionally an EMD concept is developed, evaluated with experts and implemented in the design hierarchy.
Pre-silicon verification: A pre-silicon verification plan is created which includes all relevant test cases necessary for verifying the functionality of the top-level design by simulation. If design flaws are found, circuit changes are applied and documented in detail.
Tape-out: By reaching a certain pre-silicon verification level, fabrication files are created and tape-out is performed. This project phase requires intensive interaction with the fab to perform all routines and data checks necessary.
Post-silicon verification: A post-silicon verification plan is created which includes all relevant test cases necessary for verifying the functionality of the real silicon by laboratory measurements. Additionally software needed to perform these tests is created. If silicon-issues are found, design changes are applied and documented in detail.
2nd tape-out (optional): According to silicon-issues found and re-design measures applied it might be necessary to perform a 2nd tape-out run and parts of post-silicon verification again.
Documentation: The final version of the architecture specification is released and test reports are created according to verification plans.
We have over 10 years of experience in the field of low power mixed signal circuit design. Challenging design projects have been carried out with well-known companies like Infineon Technologies, FH-Joanneum and AMS in the field of contact-less security controllers, DCDC converters and radio transmitters. Here you will find a summary of patents in which we have been actively involved.
