A Field Programmable Gate Array

Abstract

The invention relates to the technical field of field programmable gate arrays, in particular to a novel field programmable gate array capable of resisting single-event radiation reversal. The new field programmable gate array includes three parts: a configurable logic module, a general routing matrix and a one-time programming array for configuration, wherein the one-time programming array replaces the static random access memory array in the traditional field programmable gate array. It overcomes the problem that the static random storage unit is prone to single-event flipping. Adopting the present invention has the advantage of large-scale integration. In the once-programmed memory cell technology that has become popular in the industry, the standard deep submicron complementary metal oxide semiconductor process technology can be directly used without any additional mask and process correction. The invention is not easily affected by temperature, voltage, radiation, etc., and achieves a field programmable gate array (FPGA) technology with high performance, high integration and high reliability.

Description

technical field [0001] The invention relates to the technical field of field programmable gate arrays, in particular to a field programmable gate array structure resistant to single-event radiation flipping. Background technique [0002] Most of the existing Field Programmable Gate Array (FPGA, Field Programmable Gate Array) is shown in Fig. Matrix) 102 and a static random access memory array (SRAM, Static Random Access Memory) 103 for configuration (such as: Xilinx's Spartan, Virtex series, Altera's Cyclone, Stratix series, etc.). Among them, CLB101 is the main module used to implement logic functions; GRM102 provides various connection resources including local wiring resources, general wiring resources and global wiring resources; through the configuration of SRAM103, different connection relationships inside CLB101 or GRM102 can be realized. This enables user-specific logic functions to be implemented. This kind of FPGA has high integration and large capacity. [0003...
