ABSTRACT:
The present inventions provides a method and apparatus for analyzing serial data. The invention comprises a serial analyzer which receives serial data from a logic analyzer. The serial analyzer processes the data to convert the serial data into parallel words. A listing tool receives the parallel words and generates a listing to be displayed. The listing generated is arranged in a first column and the sampled serial data is in a second column, so that, a user may view simultaneously the parallel word and the serial data corresponding to it. The listing tool also receives a time and state at which each bit of serial data was captured by the logic analyzer. The listing tool arranges the time of each bit of serial data in a third column, and the state at which each bit of serial data occurred in a fourth column. Thus, the user may simultaneously view on a display the parallel words, the sampled serial data, the time of capture, and the states corresponding to each bit in the serial data. A user interface selects from several windows to configure the logic analyzer, the serial analyzer, and the listing tools. Once configured the user executes the serial analysis procedure.
