The present invention relates to integrated circuits (ICs) such as field programmable gate arrays (FPGAs). More specifically, the present invention relates to methods for converting FPGAs into standard cell integrated circuits. Method and circuits to create reduced field programmable gate arrays (RFPGA) from the configuration data of field programmable gate arrays (FPGA) are disclosed. The configurable elements of the FPGA are replaced with standard cell circuits that reproduce the functionality of the configured FPGA. Specifically, reduced logic blocks are derived from the configuration data of configurable logic blocks. Similarly, reduced input/output blocks and reduced matrices are derived from the configuration data for input/output blocks and programmable switch matrices of the FPGA, respectively. A database can be expanded as new reduced logic block models are created for configurable logic block models that were not in the database. Similarly, a database can be used for the input/output blocks and programmable switch matrices of an FPGA.
