SUMMARY OF THE INVENTION The present invention provides a method for capturing signal status, extracting the transition edge states of different signals, and arranging them in chronological order so as to be able to automatically search for a specific state combination. The present invention proposes a method of extracting signal status. First, the first signal and the second signal are received, where the first signal and the second signal respectively comprise a plurality of transition times. Next, the different types of transition states of these transition times are coded differently to obtain multiple status numbers. Then, according to the transition time of the first signal and the second signal, the corresponding state number is combined to obtain the first timing matrix and the second timing matrix respectively. The first timing matrix and the second timing matrix are combined into a combined timing matrix according to the order of the transition times. Finally, the state numbers are retrieved from the merged timing matrix to obtain a merged state matrix. In one embodiment of the present invention, the step of combining the first timing matrix and the second timing matrix into a combined timing matrix in the order of the above-described transition times includes the first timing matrix and the second timing matrix, After combining the merged timing matrices, the merged timing matrices are reordered according to the order of these transition times. In an embodiment of the present invention, after receiving the first signal and the second signal, the method further includes obtaining a transition time according to the first signal and the edge of the second signal of the ltwfdoc/ρ 200925986 state. In the embodiment of the present invention, the above state number is a decimal number. And according to the transition time of the first signal and the second signal respectively, and the step of combining the corresponding state numbers, including marking each transition state before the corresponding decimal number. In an embodiment of the present invention, the state codes are sequentially fetched by the merge timing matrix to obtain a merged state matrix, and further, the self-merging state matrix is searched for a specific state combination. After that, when the specific state combination is found in the ^ and state = array, it is not on the wave. In addition, when a specific combination of states cannot be found, the first signal and the second signal are re-received. In an embodiment of the present invention, the method for capturing a signal state, wherein before the step of receiving the first signal and the first signal, the method further includes establishing status number information to provide different encodings for different transition edges. The step of establishing the status number information includes providing the first, second, third, and fourth status numbers corresponding to the rising edge of the first signal, the β-edge, and the rising edge and the falling edge of the second signal. . The invention is based on the transition edge of different signals as rising or falling edge $, is a different state number, and according to the transition time sequence, the two numbers are combined into a merged state matrix to be in the merged state matrix. Automatically search for specific status combinations. This facilitates the operator to obtain the specific signal segments required more quickly and accurately, which is quite convenient. In order to make the above features and advantages of the present invention more comprehensible, the following is a detailed description of the preferred embodiments of the present invention. [Embodiment] Generally, it is very time-consuming and laborious to use humans to observe and search for a specific state combination in the amount of the signal. Therefore, in order to speed up the search for a specific state combination in the magic signal quantity, the present invention proposes a method of operating the signal state to automatically search for a specific state combination in the obtained merged state matrix, thereby saving human resources.

In addition, in the following embodiments, for example, the clock signal and the data signal are extracted through the oscilloscope, and the voltage matrix data of the two signals is transmitted through the General Purpose Interface Bus (GPIB) and the universal serial bus ( The Universal Serial Bus (USB) or the wireless local area network (LAN) transmission interface is transmitted to the computer system to facilitate the system to perform the signal acquisition state. However, the description is not intended to limit the scope of the invention. In order to make the content of the present invention clearer, the following specific embodiments are illustrative of the embodiments of the present invention. 2 is a block diagram of a captured signal state system in accordance with an embodiment of the invention. Referring to Figure 2, the system includes an oscilloscope 21 and a signal status program 220. The operation status program 22 includes a signal receiving module 221, a status encoding module 223, a merge module 225, a state 8 ltwf.doc/p 200925986 capture module 227, and a search module 229. The signal receiving module 221 is configured to receive a plurality of signals captured by the oscilloscope 210. The status encoding module 223 encodes different transition edges of the respective signals into different status numbers based on the status number information. The merging module 225 is used to combine the transition time and the status number of each signal, and obtain the timing matrix of each signal separately, and then combine these timing matrices into a combined timing matrix according to the order of the transition time. The state capture module 227 extracts the state number based on the merged timing matrix to obtain a chronological merged state matrix. The search module 229 is used to search for a specific state combination in the self-merging state matrix. When searching for a specific state combination, the segment of the transition time corresponding to the specific state combination is displayed to the center of the oscilloscope 21〇. When the specific state combination cannot be found, the oscilloscope 21 is driven to retake the signal. The following is a detailed description of the green steps of the capture signal (4) of the present invention in conjunction with the above-described capture signal status system. w 3 is a flow chart of a method of operating a state in accordance with an embodiment of the present invention. Please refer to Figure 2 and Figure 3. First, in step S31, the signal receiving module 221 receives the clock signal and the data signal (ie, the first signal and the second signal) from the oscilloscope 21G. The 'clock signal and the data signal respectively have multiple transition times' and each transition edge time corresponds to one transition time, and the transition edge is changed from the first state (level) of the signal to the second The state (predicted, that is, two H, the third state or from the second state to the first-shaped missing = less than two states (level). In detail, the subtraction receiving module 221 receives the clock After the signal and data signal, 200925986 ltwf.doc/p will automatically locate the transition time of the clock signal and the data signal according to the preset specification to obtain the transition edge corresponding to each transition time. Then 'in step S320 The state encoding module 223 separately encodes different transition edges corresponding to the transition times according to the state encoding information to obtain a plurality of state numbers. Further, before the encoding or receiving the signal, the signal is captured. The status program 220 can establish status code information in advance, and the status code information can be defined by the user in advance, or preset for the system. Since the transition states of the two state switches include The edge and the falling edge, therefore, when the state coded information is established, four state numbers can be provided to correspond to the rising edge and the falling edge of the clock signal and the data signal respectively. If there are more than three states, then In the embodiment, the state number is, for example, a decimal number. For example, in the state coded information, the user (or the system preset) will be in the clock. The rising edge of the signal is set to 0.2, and the falling edge is set to 〇·4. In addition, the rising edge of the data signal is set to (U, the falling edge is set to 〇3. Therefore, the state encoding module 223 can be encoded according to the state. In the setting of the information, the clock signal and the respective transition edges of the data signal are encoded one by one. After the transition edge is encoded, as shown in step S33, the merge module 225 converts according to the data signal and the clock signal respectively. The state time is combined with its corresponding state number to obtain the respective clock timing matrix (first timing matrix) of the clock signal and the data signal respectively. Data clock matrix (U-secondary matrix). When the status number is a decimal number, the merge module 225 can mark each transition time before the corresponding decimal number, so that the clock is made.

After the state encoding module 223 encodes the transition edge of the transition time 655 to 0.2 ′, the merge module 225 marks the transition time 655 before its corresponding decimal number 0.2 to obtain 655.2. The rest can be used to obtain the clock timing matrix of the clock signal (655.2, 669.4, 682.2, 696.4, 709.2, 723.4, 736.2, 750.4). On the other hand, in Fig. 4B, the transition time of the data signal includes 660, 674, 687, 701, 714, 728, 755, 782. In the case of the transition time ❹ 660, the transition edge is the falling edge. The state encoding module 223 encodes the transition edge of the transition time 660 to 0.3, after which the merge module 225 marks the transition time 660 before its corresponding decimal number of 0.3 to obtain 660.3.

Further, the merge module 225 1 first combines the clock timing moment p and the data timing matrix, and combines the merged sequence matrices to reorder the reads in the merged timing matrix according to the order of the transition time. 4A and FIG. 4B, the merging module 225 combines the modulating timing _ and the timing matrix into a combined timing matrix, and rearranges the elements in the merging matrix in order according to the transition time represented by the integer. For example, FIG. 5 is a schematic diagram of a combined timing matrix in accordance with an embodiment of the invention. Referring to Figure 5, the 'integer is the transition time' in the elements of the merged timing matrix is used to distinguish the order.

Referring to FIG. 7A to FIG. 7C, FIG. 7A shows the state of the signal to be searched by the operator, and the state code information can be used to convert 12200925986 twfdoc/p FIG. 7A into FIG. 7B' to obtain a specific state combination (4, 1 2 3 4). 1 2). Then, the search module 229 automatically merges the state matrix (see FIG. 6) to see if there is a specific state combination. When the search module 229 searches for a specific combination of states, the region & 710 (shown in FIG. 7C) of the transition time corresponding to the specific state combination is positioned to the center of the oscilloscope 21〇 for the operator to analyze. . Conversely, if the search module 229 cannot find a specific state combination, the search module 229 can send a notification message to the oscilloscope 210, so that the oscilloscope 210 can retrieve the clock signal and the data signal to repeat the above steps. S310~S350. It should be noted that the number of signals received in the above embodiment is not limited to two, and the number of the number that can be output by the oscilloscope 21 can be determined by the user and the number of signals received by the oscilloscope 21 to determine the received signal state program 22 The number of signals. The number and type of signals received are not limited here. In the above embodiment, after the state of the transition edge is edited to be the state number, the chronological merge is obtained by sorting the number according to the transition time of each transition edge. State matrix. Therefore, ^ can automatically search for the specific combination of L required by the operator (4) to reduce the errors caused by human operation, not only fast but also accurate, and can be monitored for a long time, which is quite convenient. However, the present invention has been disclosed in the above preferred embodiments, but it is not intended to be used in the present invention. Any of the prior art has a general knowledge, and may be modified and retouched without departing from the spirit and scope of the invention. , * The invention of the Weiwei Dangxiang Gaya towel please define the full-time enclosure 13 twf.doc/p 200925986.
