step S10: acquiring coordinate information of a to-be-processed device displayed in a preset graph drawing window, wherein the coordinate information comprises pin coordinates of the to-be-processed device and diagonal coordinates of a display frame of the to-be-processed device;

it should be noted that the execution main body of the method of this embodiment may be a central processing unit having the functions of obtaining pin coordinates and connecting endpoints, or may be a microcontroller, which is not limited in this embodiment.

It should be understood that the preset graphic drawing window refers to a window for drawing graphics and simulating devices in Cadence Virtuoso software, and the Cadence Virtuoso drawing window is a design which must develop optimal performance at a transistor level based on Cadence Virtuoso unified customization/simulation process support, and comprises a simulation and Radio Frequency (RF) circuit, a high-performance digital module and a graphic drawing window used as a standard cell library for constructing digital Integrated Circuits (ICs).

In a specific implementation, a designer may select a device to be processed, and the device is used as a device to be processed in this embodiment, and may be selected through a mouse or a keyboard, which is not specifically limited in this embodiment.

It should be understood that the position information refers to positions of all pins of the to-be-processed device, and the display frame of the to-be-processed device refers to a frame surrounding all the pins, and the display frame can be obtained by connecting all the pins.

According to the embodiment, the device with the graph drawing window in the selected state is used as the to-be-processed device, the position information of all pins on the to-be-processed device is obtained, the display frame of the to-be-processed device is drawn according to the position information, the to-be-processed device can be searched more accurately, the display frame is determined according to the positions of all the pins, the display frame can be determined more accurately, and therefore the lead corresponding to the pins can be generated accurately and automatically.

Further, referring to fig. 3, fig. 3 is a schematic diagram illustrating a frame of a device to be processed according to an embodiment of the lead generation method of the present invention.

As shown in fig. 3, the central portion of fig. 3 is a device to be processed, each small quadrangle represents a lead of the device to be processed, and the leads are all connected to obtain a display frame of the device to be processed, that is, a peripheral quadrangle.

Step S20: determining a frame coordinate equation of the device to be processed according to the diagonal coordinates;

it should be noted that the frame coordinate equation refers to an equation corresponding to each side of the display frame of the device to be processed, and in fig. 3, the frame coordinate equation refers to an equation of four sides of the frame connecting all the pins, for example: the frame coordinate equation is: x is 1, x is 3, y is 1, and y is 3, and other values are also possible, which is not particularly limited in this embodiment.

Step S30: determining the lead endpoint coordinates corresponding to the pins of the device to be processed according to the pin coordinates and the frame coordinate equation;

it should be noted that the lead end point coordinates refer to two end point coordinates corresponding to leads that need to be generated, where one end point coordinate is a pin coordinate, and each pin needs to generate a corresponding lead to be more conveniently connected to other devices that need to be connected.

Step S40: and connecting the lead endpoint coordinates with the pin coordinates to obtain a lead corresponding to the pin of the device to be processed.

It can be understood that each pin needs to generate a corresponding lead, so that the starting endpoint coordinate of the lead is the pin coordinate, and the lead corresponding to the pin of the device to be processed can be obtained by connecting the lead endpoint coordinate with the pin coordinate.

Further, after the step S40, the method further includes: and marking the pin name corresponding to the pin on the lead in the graph drawing window so as to obtain the pin name corresponding to the lead.

Further, referring to fig. 4, fig. 4 is a schematic diagram of a lead and a lead name according to an embodiment of the lead generation method of the present invention.

As shown in fig. 4, outside the display frame of the device to be processed in fig. 4, there is a lead generated corresponding to each pin, and each lead has a pin name corresponding to each pin, for example: 0_25, 0_24, TIP _ X2_ I0_4, etc. are names of pins corresponding to pins of the device to be processed, and this embodiment will not be described in detail.

In a specific implementation, leads around the same name as the pin of the device to be processed can be connected according to the pin name to implement the control logic required by the designer.

The method includes the steps that coordinate information of a to-be-processed device displayed in a preset graph drawing window is obtained, wherein the coordinate information comprises pin coordinates of the to-be-processed device and diagonal coordinates of a display frame of the to-be-processed device; determining a frame coordinate equation of the device to be processed according to the diagonal coordinates; determining the lead endpoint coordinates corresponding to the pins of the device to be processed according to the pin coordinates and the frame coordinate equation; and connecting the lead endpoint coordinates with the pin coordinates to obtain a lead corresponding to the pin of the device to be processed. In the embodiment, the lead is generated by acquiring the coordinate information of the device to be processed, determining the coordinate equation of the frame according to the coordinate information and determining the endpoint coordinates of the lead, and compared with the prior art in which the lead needs to be manually marked according to the pin name of the circuit symbol, the lead corresponding to the lead can be accurately and automatically generated by the above method, so that the working efficiency is improved.

Referring to fig. 5, fig. 5 is a schematic flow chart of a lead generation method according to a second embodiment of the present invention.

Based on the first embodiment described above, in the present embodiment, the step S30 includes:

step S301: selecting a target coordinate equation from the frame coordinate equations according to the abscissa and the ordinate in the pin coordinates;

it can be understood that when either the abscissa or the ordinate in the pin coordinate is the same as any one of the frame coordinate equations, the equation is the target coordinate equation, for example: the lead coordinate is (3,4), that is, the abscissa x is 3, the ordinate y is 4, the frame coordinate equation is x is 1, x is 3, y is 1, and y is 3, so that the target coordinate equation is x is 3.

Step S302: determining the pin direction of the pin of the device to be processed on the device to be processed according to the target coordinate equation;

it should be noted that the pin direction is a direction relative to the device to be processed, for example: up, down, left, right, when the target coordinate equation is x equals to 3, the lead direction can be found to be right.

Step S303: and determining the lead endpoint coordinate corresponding to the pin of the device to be processed according to the pin direction and the preset lead length.

It should be noted that the preset lead length is a lead length preset by a designer, and can be set according to actual conditions and a position relationship with surrounding devices, for example: 3. 4, 5, etc., which the present embodiment does not specifically limit.

It should be understood that the lead generation direction may be determined from the pin direction, for example: when the lead direction is upward, the generation direction of the lead should also be upward, and not toward the direction of the device to be processed. After the generation direction of the lead is obtained, the lead endpoint coordinates may be determined according to the length of the preset lead.

In the embodiment, a target coordinate equation is selected from the frame coordinate equations according to the abscissa and the ordinate in the pin coordinates; determining the pin direction of the pin of the device to be processed on the device to be processed according to the target coordinate equation; and determining the lead endpoint coordinate corresponding to the pin of the device to be processed according to the pin direction and the preset lead length. The pin direction is determined through the target coordinate equation, the direction of each pin in the to-be-processed device can be accurately determined, and then the terminal point coordinates of the lead are determined according to the pin direction and the preset lead length.

Referring to fig. 6, fig. 6 is a schematic flow chart of a lead generation method according to a third embodiment of the present invention.

Based on the foregoing embodiments, in this embodiment, the step S303 includes:

step S3031: obtaining a lead coordinate calculation equation corresponding to the pin direction;

it should be noted that the lead coordinate calculation equation is an equation required for calculating the coordinates of the lead end points, and the coordinates of the lead end points can be accurately obtained through the lead coordinate calculation equation.

It can be understood that different pin directions correspond to different lead coordinate calculation equations, and if the lead endpoint coordinates corresponding to different pins need to be obtained when the pin directions are different, the lead coordinate calculation equation corresponding to each pin direction needs to be obtained first.

Step S3032: and determining the lead endpoint coordinate corresponding to the pin of the device to be processed through the lead coordinate calculation equation according to the pin coordinate and the preset lead length.

Further, the step S3032 includes: reading a first diagonal coordinate and a second diagonal coordinate in the diagonal coordinates; and determining the lead endpoint coordinate corresponding to the pin of the device to be processed through the lead coordinate calculation equation based on the pin coordinate, the first diagonal coordinate, the second diagonal coordinate and the preset lead length.

It should be noted that the first diagonal coordinate and the second diagonal coordinate are diagonal coordinates of a display frame of the device to be processed, for example: when the first diagonal coordinate is the lower left corner coordinate of the display frame, the second diagonal coordinate must be the upper right corner coordinate of the display frame; when the first diagonal coordinate is the upper left corner coordinate of the display frame, the second diagonal coordinate must be the lower right corner coordinate of the display frame, and the frame coordinate equation can be obtained only if the diagonal coordinate of the display frame is known.

It can be understood that, in this embodiment, preferably, the first diagonal coordinate is a lower left corner coordinate of the display frame of the device to be processed, and the second diagonal coordinate is an upper right corner coordinate of the display frame of the device to be processed, at this time, the lead coordinate calculation equation is:

wherein xa is an abscissa in the pin coordinate, ya is an ordinate in the pin coordinate, wire is a preset lead length, x1 is an abscissa in the lower left corner coordinate, y1 is an ordinate in the lower left corner coordinate, x2 is an abscissa in the upper right corner coordinate, and y2 is an abscissa in the upper right corner coordinate.

In a specific implementation, when the abscissa of a lead is the same as the abscissa in the lower left corner coordinate, it indicates that the lead is located on the left side of the device to be processed, and the coordinates of the lead end point are (x1, ya), (x1-wire, ya), and since the generated lead needs to be on the left side of the lead, one end point of the lead is also located on the left side of the lead, the abscissa needs to subtract the preset lead length; when the abscissa of the pin is the same as the abscissa in the upper right-corner coordinate, the pin is positioned on the right side of the device to be processed, and the coordinates of the end points of the lead are (x2, ya), (x2+ wire, ya), and since the generated lead needs to be positioned on the right side of the pin, one end point of the lead is also positioned on the right side of the pin, the preset lead length needs to be added to the abscissa; when the ordinate of the pin is the same as the ordinate in the lower left-hand corner coordinate, it indicates that the pin is located below the device to be processed, and the terminal point coordinates of the lead are (xa, y1), (xa, y1-wire), and since the generated lead needs to be located below the pin, one terminal point of the lead is also located below the pin, so the ordinate needs to subtract the preset lead length; when the ordinate of the pin is the same as the ordinate in the upper right-hand coordinate, it indicates that the pin is located on the upper side of the device to be processed, and the coordinates of the lead end point are (xa, y1), (xa, y2+ wire), because the generated lead needs to be located on the upper side of the pin, one end point of the lead is also located on the upper side of the pin, and therefore the ordinate needs to be added with the preset lead length.

In the embodiment, an equation is calculated by obtaining lead coordinates corresponding to the pin direction; and determining the lead endpoint coordinate corresponding to the pin of the device to be processed through the lead coordinate calculation equation according to the pin coordinate and the preset lead length. In the embodiment, the lead endpoint coordinates corresponding to each pin are obtained through the lead coordinate calculation equation corresponding to each pin direction, the lead endpoint coordinates in each direction can be generated according to actual conditions, the accuracy of the lead endpoint coordinates is ensured, and therefore the lead corresponding to the pin can be accurately and automatically generated.

Furthermore, an embodiment of the present invention further provides a storage medium, where the storage medium stores a lead generation program, and the lead generation program, when executed by a processor, implements the steps of the lead generation method as described above.
