Abstract

The invention provides an SRAM (Static Random Access Memory) type FPGA (Field Programmable Gate Array) crosstalk verification method, which is realized based on an SRAM type FPGA crosstalk verification device. The device comprises a PC (Personal Computer), an FPGA socket, a signal input unit and an adjustable load capacitor. The SRAM type FPGA crosstalk verification method comprises maximum / minimum crosstalk noise verification in a single I / O-BANK (Input / Output-BANK), crosstalk affection between the adjacent I / O-BANKs and relationship between the crosstalk and each of the output turn speed, the input signal edge and the load capacitor; during the verification process, the PC provides various configuration files to an FPGA to be verified; and moreover, under various testing conditions, the noise level of an interfered line in the FPGA to be verified is detected to realize crosstalk noise verification on an FPGA component.

Description

technical field [0001] The invention relates to a SRAM type FPGA crosstalk verification method, which belongs to the technical field of FPGA application verification. Background technique [0002] With the development of semiconductor technology, the integration level of SRAM FPGA is constantly increasing. Therefore, on the one hand, the I / O ports of the FPGA are increasing and the distribution is more dense, making it easier for the I / O to interfere with each other; on the other hand, due to power consumption and heat dissipation, the operating voltage of the FPGA becomes lower, making the I / O more sensitive to disturbances. Therefore, in the application process of FPGA, crosstalk noise is very likely to be generated between I / Os, and can have a more significant impact. Therefore, the crosstalk noise between the I / Os of the FPGA device itself and the tolerance to the crosstalk noise have become a standard to measure the pros and cons of the FPGA device.
