Physical Design Automation For Large Scale Field Programmable Analog Arrays

Field-programmable analog arrays (FPAA) are integrated circuits with a collection of analog building blocks connected through a wire and switch fabric to achieve reconfigurability similar to the FPGAs of the digital domain. Like FPGAs, FPAAs can help reduce the time and money costs of the integrated circuit design cycle and make analog design much easier. In recent years, several types of FPAAs have been developed. Among these, FPAAs that use floating-gate transistors as programming elements have shown great potential in scalability because of the simplicity they provide in configuring the chip. Existing tools for programming FPAAs tend to be device specific and aimed at specific tasks such as filter design. To move FPAAs to the next step, more powerful and generic placement and routing tools are necessary.
