Alliance: FOSS VLSI/CAD System
Alliance is a complete set of free cad tools and portable libraries for VLSI design. It includes a VHDL compiler and simulator, logic synthesis tools, and automatic place and route tools. A complete set of portable CMOS libraries is provided. Alliance is the result of a twelve year effort spent at SoC department of LIP6 laboratory of the Pierre & Marie Curie University (Paris VI, France). Alliance has been used for research projects such as the 875 000 transistors StaCS superscalar microprocessor and 400 000 transistors IEEE Gigabit HSL Router.
Alliance VLSI CAD System is free software. Binaries, source code and cells libraries are freely available under the GNU General Public License (GPL). You are welcome to use the software package even for commercial designs without any fee. You are kindly requested to mention: "Designed with Alliance © LIP6, Université Pierre et Marie Curie".
ICs Designed with Alliance
- Smartlabs/Smarthome designed a complete circuit in the XFAB XH035 technology (2014).
- Tokai University (Shimizu Lab) designed the SNX, a 16 bits processor in the ROHM 0.18µm (2010).
- Improved Standard Cell libraries and documentation on how to design them, by Graham Petley: VLSI Technology
- A book presenting Alliance in depth: Introduction to VLSI CMOS Circuits design by Carlos SilvaCardenas, Takeo Yoshida & Alberto Palacios Pawlovsky.
- For Spanish readers, a set of tutorials made by Miguel Eduardo Flores Gomez from Don Bosco University: Tutorial de Alliance

[video] How to Model RF Passive Devices: Spiral Inductors
How to Model RF Passive Devices: Spiral Inductors
With increasing operating frequencies, the modeling of passive components becomes increasingly important, and there exist no ready-to-use models for inductors, resistors, capacitors etc. Based on the other video of this fundamental device modeling series, (How to Model RF Capacitors and Resistors), this video extends the topic to modeling RF Spiral Inductors. It explains how to develop a Spice model based on verified S-Parameter measurements. Applying an easy to follow, step by step procedure, the video walks you through the entire modeling flow for on-wafer inductors, using the Keysight Measurement and Modeling Software IC-CAP.
The IC-CAP project (modeling spiral inductors with and without metal-1 shielding) can be downloaded together with a detailed pdf explaining the steps demonstrated in the video.
