METHOD OF DESIGNING SUBSTRATE INCLUDING PROGRAMMABLE LOGIC CIRCUIT SUCH AS FPGA

摘要

PROBLEM TO BE SOLVED: To provide a layout having the shortest wiring distance between an FPGA (Field Programmable Gate Array) pin and a peripheral circuit pin corresponding thereto.;SOLUTION: This substrate design method includes: a step for performing the circuit design of a pin-unassigned FPGA 3 and a memory 5 as a pin-assigned peripheral circuit; a step for laying out the FPGA 3 and the memory 5 on a substrate according to the circuit design; and a step for assigning the FPGA pin 40 among the FPGA pins 34, 35, 40 and 41 to the pin connected to the address pin 51 of the corresponding memory 5 with the shortest wiring distance.;COPYRIGHT: (C)2010,JPO&INPIT
