A Methodology for FPGA to Structured-ASIC Synthesis and Verification

Structured-ASIC design provides a mid-way point between FPGA and cell-based ASIC design for performance, area and power, but suffers from the same increasing verification burden associated with cell-based design. In this paper we address the verification issue with a methodology and fabric to directly tie FPGA prototype and functional in-system verification with a clean migration path to structured ASIC. The most important aspects of this methodology are the use of physically identical blocks for difficult-to-verify PLLs, I/O and RAM and a structured re-synthesis of FPGA logic blocks to target cells that guarantees anchor points for easy formal verification
