NOR flash configuration module verification method, system, device and storage medium

Abstract

The invention relates to the field of semiconductor testing, and particularly to a NOR flash configuration module verification method which comprises the following steps: generating a config sequenceand a flash sequence, extracting a config excitation data packet from the config sequence based on an instruction, and extracting a flash excitation data packet from the flash sequence; performing a first simulation operation by using the config excitation data packet and the flash excitation data packet to output a first simulation result; injecting the comparison model, and performing a second simulation operation to output a second simulation result; and finally, comparing the first simulation result with the second simulation result, ending the simulation if the comparison is correct, andfinishing the error statistics simulation if the comparison is wrong. By designing a config sequence, configuration values meeting requirements can be randomly generated for different algorithm stagesand simulation modes, the verification space is expanded, and the verification completeness is improved; based on the comparison model, the second simulation result serving as the comparison reference can be accurately output, the first simulation result and the second simulation result are automatically compared, and the verification accuracy and the verification efficiency are improved.

Description

technical field [0001] The invention relates to the field of semiconductor testing, in particular to a NOR flash configuration module verification method, system, device and storage medium. Background technique [0002] The NOR flash configuration module has an independent storage space in the flash chip, and its configuration values ​​vary according to the capacity and function of the flash. This module is responsible for chip power-on configuration, read / write algorithm mode selection, mode configuration, analog circuit voltage and current selection, etc. As a basic functional module of the flash chip, it runs through the entire chip verification cycle and plays a vital role in the chip verification period . [0003] At present, the NOR flash configuration module verification mainly adopts the manual setting of single configuration value, manual inspection of verification results or semi-automatic comparison. However, the application scenarios and configuration module fu...
