Technology mapping and retargeting for field-programmable analog arrays

Rapid prototyping followed by technology retargeting provides a fast and cost-effective approach to analog system synthesis. Field-programmable analog arrays (FPAAs) enable rapid implementation of a function-compliant prototype, while technology retargeting converts the functional FPAA prototype to an ASIC. We first address the FPAA technology mapping problem. A novel structural approach based on hierarchical pattern matching and covering is employed to map the analog behavior onto the FPAA. We then address the issues of technology retargeting and design reuse, and present out FPAA-ASIC retargering strategy. We present experiments and a design example for FPAA technology mapping and retargeting
