Technology

ODE4EC-AMS improves the analogue, mixed-signal and RF design flow from simulation to layout. All tool work goes into existing open source projects, so the community can use the results directly.

Tools we improve

Tool	What we add	Partners
ngspice	Large-signal transient noise, stronger mixed-signal simulation, interfaces to Verilog-A and HDL simulators	UDE
OpenVAF	Transient noise for Verilog-A models, conversion of common SPICE device models to Verilog-A	UL
KLayout PEX	Parasitic extraction with several engines, from fast estimates to high accuracy	JKU, SAL
FasterCap and FRW	2D, 2.5D and 3D capacitance field-solver back-ends for KLayout	UTH
Elmer FEM	Electromagnetic and S-parameter simulation for IC layouts, linked to KLayout through KQCircuits	CSC, IQM
Coriolis	Procedural placement and routing for analogue circuits	Sorbonne Université

Analogue design automation

Analogue layout is still largely drawn by hand. The project develops MOSAIC, a modular and extensible framework for analogue design generation. It brings together circuit generators, layout generators and automated sizing, including machine-learning-based optimisation, from transistor level up to system level.

Industrial partners bring real design cases, so that the framework is shaped by what product teams need.

PDKs and silicon

The tools are validated on mature technologies, starting with IHP's open source SG13G2 PDK (130 nm SiGe BiCMOS) and including flexible integrated circuits from Pragmatic Semiconductor.

Industrial and research partners design analogue, mixed-signal and RF IP blocks with the new flow. The designs are fabricated in multi-project wafer (MPW) runs and measured, and the results feed back into tool and PDK development.

Open source licences

Tools, generators and IP developed in the project are released under OSI-approved open source licences. Whether a PDK can be fully open depends on the foundry; the project works towards open PDKs or, where that is not possible, PDKs that work with open source tools.
