Data pickup processing method for logic analyzer and apparatus thereof

Abstract

A logic analyzer data retrieving method used in a logic analyzer formed of a control unit, a memory unit, and a data retrieving circuit, is disclosed to include the step of driving the data retrieving circuit of the logic analyzer to receive a time delay default value and to store in a buffer in a time delay circuit, and the step of triggering the preset of a first counter and transferring the default value from the buffer to the first counter to drive the first counter to start counting when a clock qualifier signal entered so as to obtain a complete clock enable signal when the first counter counted up to the default value and the output of the clock enable became low.

Description

technical field [0001] The present invention relates to a method and device for data acquisition and processing of a logic analyzer, especially an analyzer capable of capturing complete clock enable signals, and the analyzer can also allow users to understand two clock enable signals How much time interval between signals. Background technique [0002] By the way, in today’s increasingly digitalized electronic products, the traditional oscilloscope is no longer enough to measure the signals of more than 8 to 16 channels. Although the online simulator (ICE) can solve many digital problems, the real timing problem cannot be solved. Processed by an online simulator that focuses on software development, coupled with the fact that the online simulator is dedicated to a specific microcomputer system, the logic analyzer has become one of the necessary measuring instruments for engineers. It can convert the required data Expressed in a very organized format (Format), the user can e...
