This discussion reviews the current capabilities of large-scale Field Programmable Analog Arrays (FPAA) and considers the future potential of these SoC FPAA devices, including techniques to enable ubiquitous use of FPAA devices similar to FPGA devices. Today's FPAA devices include integrated analog and digital fabric as well as specialized processors and infrastructure, becoming a platform of mixed-signal development as well as analog-enabled computing. Investigating the scaling of FPAA devices shows the potential fine-grain capabilities through analyzing the tradeoff between granularity and flexibility as well as the opportunities through CMOS scaling.
