ALIGN (Analog Layout, Intelligently Generated from Netlists) is an open-source automatic layout generation flow for analog circuits. ALIGN translates an input SPICE netlist to an output GDSII layout, specific to a given technology, as specified by a set of design rules. The flow first automatically detects hierarchies in the circuit netlist and translates layout synthesis to a problem of hierarchical block assembly. At the lowest level, parameterized cells are generated using an abstraction of the design rules; these blocks are then assembled under geometric and electrical constraints to build the circuit layout. ALIGN has been applied to generate layouts for a diverse set of analog circuit families: low frequency analog blocks, wireline circuits, wireless circuits, and power delivery circuits.
Recent years have witnessed the fast development of quantum computing. Researchers around the world are eager to run larger and larger quantum algorithms that promise speedups impossible to any classical algorithm. However, the available quantum comp
We present our experience of designing a single-chip controller for advanced digital still camera from specification all the way to mass production. The process involves collaboration with camera system designer, IP vendors, EDA vendors, silicon wafe
Layout fracturing is a fundamental step in mask data preparation and e-beam lithography (EBL) writing. To increase EBL throughput, recently a new L-shape writing strategy is proposed, which calls for new L-shape fracturing, versus the conventional re
The increasing complexity of modern configurable systems makes it critical to improve the level of automation in the process of system configuration. Such automation can also improve the agility of the development cycle, allowing for rapid and automa
Triple patterning lithography (TPL) is one of the most promising techniques in the 14nm logic node and beyond. However, traditional LELELE type TPL technology suffers from native conflict and overlapping problems. Recently LELEEC process was proposed
