# Synthesis and Optimization of Digital Circuits by …

AB - While digital circuit designs are now fully automated and can be delivered extremely quickly, the analogue part of a typical ASIC still needs to be designed manually. This paper discusses a way forward to overcome one of the obvious difficulties in analogue synthesis namely the lag in the development of appropriate synthesis methodologies to support mixed-signal ASICs. The recent emergence of VHDL-AMS has enabled high-level analogue descriptions to be synthesized into hardware automatically. An example of synthesis and optimization of a 1 GHz VLSI LC bandpass filter is presented based on identification of synthesizable constructs from a VHDL-AMS parse tree.

## High-Level Synthesis of Digital Circuits - ScienceDirect

AB - Traditional digital circuit synthesis flows start from an HDL behavioral definition and assume that circuit functions are almost completely defined, making don't-care conditions rare. However, recent design methodologies do not always satisfy these assumptions. For instance, third-party IP blocks used in a system-on-chip are often overdesigned for the requirements at hand. By focusing only on the input combinations occurring in a specific application, one could resynthesize the system to greatly reduce its area and power consumption. Therefore we extend modern digital synthesis with a novel technique, called SWEDE, that makes use of extensive external don't-cares. In addition, we utilize such don't-cares present implicitly in existing simulation-based verification environments for circuit customization. Experiments indicate that SWEDE scales to large ICs with half-million input vectors and handles practical cases well.

## MicheliSynthesis and Optimization of Digital Circuit.

As the degree of precision of the synthesized gate is explicitly minimized by means of this optimization procedure, the enhanced algorithm allows for more accurate quantum gates to be synthesized than what the original Solovay-Kitaev algorithm achieves.

Lab
Three projects in which students develop CAD tools for circuit analysis and synthesis. C++ programming is required. Being familiar with algorithms and data structures (EECS 281) is recommended.
