A Configuration Method of Field Programmable Gate Array

Abstract

The invention discloses an onsite programmable gate array configuration method. An onsite programmable gate array comprises multiple logic modules, multiple wiring resources in an X-direction, multiple wiring resources in a Y-direction, an excitation signal input end and a response signal output end. Each logic module is composed of logic units and comprises a lower side input end, a lower side output end, a left side input end, a left side output end, an upper side input end, an upper side output end, a right side input end and a right side output end. A configuration mode of "four-in-four-out" is adopted by each logic module so that the input ends and the output ends of the logic modules are utilized to the largest limit and number of the required ports is greatly reduced, and thus the method is applicable to fault detection of connection between the logic modules and local interconnection resources in the onsite programmable gate array.

Description

technical field [0001] The invention relates to the field of field programmable gate array local interconnection resource failure detection technology field, in particular to a field programmable gate array configuration method. Background technique [0002] The user programmability and low development cost of field-programmable gate arrays (FPGAs) make them an important technology for implementing modern circuits and systems. Compared with Application Specific Integrated Circuits (ASIC), FPGA's low R&D cost and short development cycle make it an important core technology for realizing modern digital circuits and systems, and its market share is also increasing year by year. The testing of FPGA is becoming more and more important, especially the fault detection of local interconnection resources of FPGA. [0003] Generally speaking, FPGA testing is divided into mid-test and final testing, that is, the test when the FPGA chip tape-out ends without dicing and the test after d...
