Function traversal testing method for high performance SoC FPGA

Abstract

The invention belongs to the technical field of integrated circuits, and relates to a function traversal testing method for high performance SoC FPGA. A set of complete function traversal testing method is established for CLB, BRAM, DSP, CM, IOB, clock network, interconnection and other resources in the high performance SoC FPGA, and corresponding bit stream is generated to apply excitation on an FPGA port and read back the response of the FPGA port. The response is compared with an expected result to realize the traversal covering test on the Soc FPGA resources. The test method is applicable to various high performance Soc FPGA with complex function and abundant resources and if of high application value in the FPGA test field. The test coverage rate and the test efficiency are high, the test cost is low, and the transferability and the universality are good.

Description

technical field [0001] The invention belongs to the technical field of integrated circuits, and in particular relates to a method for performing function traversal coverage tests on internal resource modules in high-performance SoC FPGA chips. Background technique [0002] Field Programmable Gate Array (Field Programmable Gate Array, FPGA) is a chip that can change its internal circuit logic function through programming. [0003] High-performance SoC (system on a programmable chip)-FPGA is the mainstream development trend of FPGA chips in recent years. It is characterized by programmable logic units (CLB: Configurable Logic Block) and programmable input and output units (IOB: Input Output Box) and interconnect resources, it also integrates block memory (BRAM), digital signal processor (DSP: Digital Signal Processing), clock manager (CM: clock managers) and other resources [1] , while retaining the customization flexibility of the FPGA itself, an efficient general-purpose i...
