A successful made-for-analog solution should be easy and intuitive for an analog designer to use. Such a solution would need to read in industry-standard schematic formats. Constraints-handling should be as streamlined as possible, ideally, the system would be able to derive constraints automatically from the circuit topology (as physical constraints may only exist in Post-It form if at all). In order to create manual-quality layout results, placement and routing would have to be considered simultaneously. The constraints and layout would need to be editable by the layout engineer at each and every stage of the process. Finally, the resulting layout should be electrically correct and DRC/LVS clean.
