We stock a large number of various high precision/low-power analog IPs. If you need, based on existing design data, we can convert analog IP process. We have developed powerful tool called FPNA (Floor Plan Noise Analysis) to achieve robust floor plan early in the design.

Substrate Noise Analysis Tools (FPNA)

In analog-digital mixed LSI design, how to tame the transient supply current change during CMOS logic operation and its propagation in substrate, which cause cross-talk noise, has been one of the major issues. We have developed powerful tool called FPNA (Floor Plan Noise Analysis) to achieve robust floor plan early in the design.


  • You can estimate the influence of cross-talk noise at the floorplan level before the detailed layout design.
  • GDS data is no longer necessary. Based on the Si substrate resistivity and guard ring information, you can simulate in a short time.
  • By applying FPNA for multiple floorplan ideas, you can find the best solution in a short time.

You can reduce the number of reworking and costs by the quantitative estimation of crosstalk noise by using FPNA. As a result, mixed signal LSI design is optimized, and design efficiency is increased. It is one of the essential key technologies in the development of mixed-signal LSIs having both analog/RF circuits of large dynamic range and large-scale logic circuits on a single die. Noise analysis technologies can be offered in various forms shown below.
