Progress Toward VLSI-Capable EDA Tools for Superconductive Digital Electronics

Synopsys is developing a complete design flow tool set for use with superconductive digital logic, initially focusing on ERSFQ and AQFP technologies. This flow begins with design synthesis of a high level logic description, automating cell placement, routing, and design validation. Circuit simulation and statistical analysis tools utilizing advanced TCAD techniques are also under development. The flow will provide a tool set to address all requirements culminating with a tape-out. The proposed flow will parallel the functionality used routinely in the semiconductor industry, but is still at a very early stage of development for superconductors.
