Automatic transistor and physical design of FPGA tiles from an architectural specification

One of the most difficult and time-consuming steps in the creation of an FPGA is its transistor-level design and physical layout. Modern commercial FPGAs typically consume anywhere from 50 to 200 man-years simply in the layout step. To date, automated tools have only been employed in small parts of the periphery and programming circuitry. The core tiles, which are repeated many times, are subject to painstaking manual design and layout. In this paper we present a new system (called GILES, for Good Instant Layout of Erasable Semiconductors) that automatically generates a transistor-level schematic from a high-level architectural specification of an FPGA. It also generates a cell-level netlist that is placed and routed automatically. The architectural specification is the one used as input to the VPR [3] architectural exploration tool. The output is the mask-level layout of a single tile that can be replicated to form an FPGA array. We describe a new placement tool that simultaneously p...
