Embodiment Construction

[0069] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

[0070] The embodiment of the present disclosure provides a signal detection method, which can detect the result obtained by the simulation of the setting simulator, so as to automatically judge whether the simulation result is correct. The setting simulator is used for simulating the chip under test to generate a simulation file, and the simulation file includes the information of the simulation wa...

Abstract

The embodiment of the invention provides a signal detection method and device, and the device comprises the steps: defining the information of a correct output waveform of a to-be-detected signal in an excitation file, employing a set simulator, carrying out the simulation of a to-be-detected chip, so as to generate a simulation file, and enabling the simulation file to comprise the information of a simulation waveform of the to-be-detected signal, noise in the simulation waveform is screened out to obtain a to-be-compared file, and the to-be-compared file and the excitation file are compared to generate a detection result file; or comparing the correct output waveform with the simulation waveform to obtain a candidate detection result, and screening out a result of noise points in the candidate detection result to generate a detection result file. According to the mode, the correctness of a simulation result is improved and the signal detection efficiency is improved by automatically comparing the information of the correct output waveform and the simulation waveform of the to-be-detected signal and screening out false error points.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of semiconductors, and in particular, to a signal detection method and device. Background technique [0002] In the process of developing, designing and debugging the memory, the function of the memory needs to be simulated and verified, and the simulation software can be used to simulate and verify the memory. The memory is, for example, dynamic random access memory (Dynamic Random Access Memory, referred to as DRAM), and the simulation software is, for example, Finesim, which is a high-performance accelerated general-purpose analog circuit simulator (Simulation program with integrated circuit emphasis, referred to as SPICE), It is widely used for its advantages of speed and accuracy. [0003] In the simulation verification of the memory, there are a large number of signals that need to be simulated and verified, and correspondingly, thousands of waveform result files will be generat...
