[0044] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] Currently, with the rapid development of integrated circuits, more and more interfaces are adopted on chips, and the speed is also getting faster and faster. As a result, the signal integrity problems are becoming increasingly prominent. The pressure to ensure signal integrity requirements before chip tape-out is increasing. Therefore, after the interface signals are determined, it is possible to construct transmission lines based on the application scenarios of the interfaces to achieve the purpose of estimating the feasibility of signal integrity.

[0046] The prior art estimates whether the indicators of the driving load and the signal waveform meet the requirements according to the parasitic capacitance generated per unit area of the transmission line. Such a method is relatively rough and has low accuracy.

[0047] For this reason, the present application provides a transmission line model building solution, which can build an automatic transmission line model with higher signal transmission quality and shorter modeling time, and improve the design efficiency.

[0048] Refer to Figure 1 As shown, an embodiment of the present invention discloses a transmission line model building method, including:

[0049] Step S11: Configure parameter information of the isolation ground and the intermediate dielectric layer of the transmission line through a preset graphical interface to obtain corresponding transmission line parameter information; the isolation ground is a position area for isolating different transmission lines.

[0050] In this embodiment, as Figure 2 shown, configure parameter information of the isolation ground of the transmission line, the dielectric constants of the upper, middle and lower dielectric layers, the thickness and width of the dielectric layers, the dissipation factor and the number of differential pairs through a preset graphical interface. It can be understood that by configuring the relevant parameters of the transmission line model in a preset graphical interface, for example, the graphical interface of Matlab (Matrix Laboratory), and performing an assignment activity on the module with the module attributes configured, input the configuration information that needs to be concerned in the modeling through a dynamic text box, and the content in the dynamic text box can be automatically assigned to the variables defined in the script when creating the script to achieve the purpose of variable introduction. Among them, it should be noted that in the process of configuring parameter information in the present application, the configuration of the number of differential pairs is additionally added to further complete the configuration of the isolation ground and the intermediate dielectric layer.

[0051] Step S12: Based on the transmission line parameter information, perform position positioning on the corresponding layer structure to obtain the position positioning information of each layer structure, and determine the modeling positions of the isolated ground and the intermediate dielectric layer based on the position positioning information, so as to obtain a modeling script for creating a transmission line model.

[0052] In this embodiment, the preset position coordinates on the bottom metal layer are determined as the origin coordinates; based on multiple groups of differential pair information, the width information of the isolated ground, and the width information of the dielectric layer, the width information of the transmission line model is determined; based on the thickness information of the bottom metal layer, the position positioning coordinates of the lower dielectric layer are determined; based on the width information of the isolated ground and the number of differential pairs, the position positioning coordinates of the intermediate dielectric layer are determined. It can be understood that the coordinate information at the lower left corner of the bottom metal layer is positioned as the origin coordinates, and information positioning is performed layer by layer in this way. First, the bottom metal layer is positioned and the module script is generated. The thickness of this module is the layer thickness, and the width is the width occupied by multiple groups of differential pair signals, the isolated ground, and the dielectric layers on both sides, thus forming the width of the entire model. The calculation code for the entire width is as follows:

[0053] / / Calculation of the total model width

[0054] width_total←left_nu+w_line_nu*(3*line_number_nu+1)+s_line_nu*line_number_nu+ss_line_nu*2*line_number_nu+right_nu;

[0055] Among them, width_total represents the total model width, left_nu represents the width of the left dielectric layer, w_line_nu represents the width of the intermediate transmission line, s_line_nu represents the width between transmission lines, line_number_nu represents the width of the transmission line, ss_line_nu represents the width between differential pairs, and right_nu represents the width of the right dielectric layer.

[0056] In this embodiment, with reference to Figure 3As shown, after the information configuration of each module is completed, the positioning of the lower-layer medium only needs to position based on the thickness information of the bottom metal layer, and the width information follows the above total width value. At this time, the ordinate value of the coordinate information at its lower left corner is the value of the bottom metal thickness. Determining the position positioning coordinates of the intermediate dielectric layer based on the width information of the isolated ground and the number of differential pairs includes: determining the number of loop executions based on the number of differential pairs; looping and executing the step of determining the position positioning coordinates of the intermediate dielectric layer based on the number of loop executions and the width information of the isolated ground. The coordinate information of the intermediate dielectric layer needs to be calculated according to the isolated ground and the number of differential pairs, and the information of each intermediate dielectric layer changes with the number of differential pairs. The specific width calculation is as follows. Where i represents the current number of differential pairs, and the positioning of the intermediate dielectric layer requires looping the number of differential pairs.

[0057] / / Calculation of the starting horizontal coordinate of the dielectric layer on the left side of the differential pair

[0058] x_start_l←left_nu+w_line_nu*(3*i-2)+s_line_nu*(i-1)+ss_line_nu*(2*i-2);

[0059] / / Calculation of the starting horizontal coordinate of the intermediate dielectric layer of the differential pair

[0060] x_start_c←left_nu+w_line_nu*(3*i-1)+s_line_nu*(i-1)+ss_line_nu*(2*i-1);

[0061] / / Calculation of the starting horizontal coordinate of the dielectric layer on the right side of the differential pair

[0062] x_start_r←left_nu+w_line_nu*3*i+s_line_nu*i+ss_line_nu*(2*i-1);

[0063] / / Calculation of the starting horizontal coordinate of the rightmost dielectric of the intermediate dielectric layer

[0064] x_start_Die_r←left_nu+w_line_nu*(3*i+1)+s_line_nu*i+2*i*ss_line_nu;

[0065] In this embodiment, after calculating the positioning of the above layer structure, the positioning of the upper dielectric layer and the top metal layer will be carried out, mainly the longitudinal coordinate positioning, and the calculation information mainly comes from the thickness of each layer. The horizontal coordinate information is the width of the entire model.

[0066] It should be noted that when modeling the intermediate layer differential pair, isolation ground, and intermediate dielectric layer, it is all completed in a cyclic manner, and the number of cycles is the number of differential pairs. The following is the loop structure. The difference in modeling for the differential pair, isolation ground, and intermediate dielectric layer lies in the above coordinate calculation information.

[0070] end

[0071] In this embodiment, it can be understood that according to the information provided by the information configuration module, information matching of different layer structures and calculation of modeling position information are performed, so as to realize the multi-layer stacking and nesting of each model, without manually calculating the positioning information and the types of modules used during manual modeling.

[0072] Step S13: Generate a target modeling script that runs on finite element analysis software based on the modeling script, so as to use the target modeling script to build a model of the transmission line.

[0073] In this embodiment, modeling is performed based on the ANSYS software. A parameter configuration environment is constructed through MATLAB, and a Python script that can realize automatic modeling is created. Then the script is loaded into the HFSS (High Frequency Structure Simulator) software to automatically perform transmission line modeling.

[0074] It can be seen that this application discloses a method for building a transmission line model, including: configuring parameter information of the isolation ground and intermediate dielectric layer of the transmission line through a preset graphical interface to obtain corresponding transmission line parameter information; the isolation ground is a position area for isolating different transmission lines; based on the transmission line parameter information, position positioning of the corresponding layer structure is performed to obtain the position positioning information of each layer structure, and based on the position positioning information, the modeling positions of the isolation ground and the intermediate dielectric layer are determined to obtain a modeling script for creating a transmission line model; a target modeling script that runs on finite element analysis software is generated based on the modeling script, so as to use the target modeling script to build a model of the transmission line. Thus, it can be seen that this application designs a positioning method for the routing position of the routing layer of a strip transmission line model with an isolation zone by configuring parameter information such as the isolation ground, and realizes the rapid generation of the modeling script based on the configuration of relevant parameters through a preset graphical interface, shortening the modeling time, improving work efficiency and the integrity of the transmission line signal in the early estimated time, and improving design efficiency.

[0075] Referring to Figure 4 as shown, an embodiment of the present invention discloses a specific method for building a transmission line model. Compared with the previous embodiment, this embodiment further explains and optimizes the technical solution. Specifically:

[0076] Step S21: Configure parameter information for the isolation ground and the intermediate dielectric layer of the transmission line through a preset graphical interface to obtain corresponding transmission line parameter information; the isolation ground is a position area for isolating different transmission lines.

[0077] Step S22: Configure the environment of the finite element analysis software and create a new planar engineering project, and then configure the dielectric properties of the upper, middle, and lower dielectric layers based on the dielectric constants and dissipation factors of the upper, middle, and lower dielectric layers through the preset graphical interface.

[0078] In this embodiment, the environment is pre-configured on the ANSYS software, and then a design project is created. For example: create Q2DDesign, then save the input project name, and select the corresponding folder for saving to implement the initialization configuration of the ANSYS software. The code for the initialization configuration is as follows:

[0079] / / ANSYS information configuration

[0080] file_out←fopen(file_name,'wt');

[0081] output(file_out,'import ScriptEnv');

[0082] output(file_out,'ScriptEnv.Initialize("Ansoft.ElectronicsDesktop")');

[0083] output(file_out,'oDesktop.RestoreWindow()');

[0084] output(file_out,'oProject=oDesktop.NewProject()');

[0085] output(file_out,'oProject.InsertDesign("2D Extractor","2DExtractorDesign1","","")');

[0086] output(file_out, 'oDesign = oProject.SetActiveDesign("2DExtractorDesign1")');

[0087] output(file_out, 'oEditor = oDesign.SetActiveEditor("3D Modeler")');

[0088] output(file_out, 'oDefinitionManager = oProject.GetDefinitionManager()');

[0089] In this embodiment, referring to Figure 5 As shown, the dielectric constant and dissipation factor of the upper, middle, and lower dielectric layers are configured for the dielectric properties inside the software. It should be noted that this function will configure the properties of the dielectric material without calculating the position information of the dielectric layer.

[0090] Step S23: Based on the transmission line parameter information and the dielectric properties of each layer, perform position positioning on the corresponding layer structure to obtain the position positioning information of each layer structure, and based on the position positioning information, determine the modeling positions of the isolated ground and the intermediate dielectric layer to obtain a modeling script for creating a transmission line model.

[0091] In this embodiment, the position of each layer structure is positioned by configuring the transmission line parameter information of the graphical interface and the properties of the dielectric material in ANSYS software to obtain the positioning information of each layer structure. It can be understood that the position positioning information of the isolated ground is determined by the number of differential pairs, and the number of cycles of calculating the isolated ground is used for positioning. Further, the positioning information of the intermediate dielectric layer is calculated jointly by the isolated ground information and the number of differential pairs. It should be noted that in this application, by obtaining the number of differential pairs and the information of the isolated ground, a modeling script for a transmission line model with ground plane isolation between differential pairs can be generated. Based on the modeling script, the corresponding transmission line model is automatically generated to reflect the wiring situation of high-speed signals in the actual environment and realize the simulation of the routing environment of most interface signals.

[0092] Step S24: Configure the boundaries of the transmission line model to obtain boundary configuration information; add the boundary configuration information to the modeling script to obtain a target modeling script for running on the finite element analysis software.

[0093] In this embodiment, boundary configuration information of the entire transmission line model also needs to be added to the output script. The boundaries of the transmission line model will be set to isolate the transmission line model from the entire plane. The code for the boundary configuration information is as follows:

[0094] / / Boundary configuration information

[0095] output(file_out,'oModule=oDesign.GetModule("BoundarySetup")');

[0096] output(file_out,'oModule.AssignSingleReferenceGround(');

[0097] output(file_out,'[');

[0098] output(file_out,'"NAME:RectangleTop",');

[0099] output(file_out,['"Objects:=",[',rectangleshield,'],']);

[0100] output(file_out,'"SolveOption:=","SolveInside",');

[0101] output(file_out,'"Thickness:=","-1000mm"');

[0102] output(file_out,')');

[0103] In this embodiment, configuration information for simulation analysis is created, and the configuration information for simulation analysis and the boundary configuration information are added to the modeling script to obtain a target modeling script that can run on finite element analysis software. It can be understood that after the creation of the transmission line model is completed, configuration information for simulation analysis is automatically created. The simulation mainly focuses on two aspects: CG and RL. Among them, CG represents the calculation of capacitance and conductance for the plane, and RL is the calculation of resistance and inductance for the model. The code for the simulation analysis information is as follows:

[0104] / / Simulation analysis information

[0105] output(file_out,'oModule=oDesign.GetModule("AnalysisSetup")');

[0106] output(file_out,'oModule.InsertSetup("2DMatrix",');

[0108] output(file_out,'"NAME:Setup1",');

[0109] output(file_out,['"AdaptiveFreq:=","',solve_freq,'GHz",']);

[0110] output(file_out,'"SaveFields:=",True,');

[0111] output(file_out,'"Enabled:=",True,');

[0112] output(file_out,'[');

[0113] output(file_out,'"NAME:CGDataBlock",');

[0114] output(file_out,'"MaxPass:=",10,');

[0115] output(file_out,'"MinPass:=",1,');

[0116] output(file_out,'"MinConvPass:=",1,');

[0117] output(file_out,'"PerError:=",1,');

[0118] output(file_out,'"PerRefine:=",30,');

[0119] output(file_out,'"DataType:=","CG",');

[0120] output(file_out,'"Included:=",True,');

[0121] output(file_out, '"UseParamConv:=", False,');

[0122] output(file_out, '"UseLossyParamConv:=", False,');

[0123] output(file_out, '"PerErrorParamConv:=", 1,');

[0124] output(file_out, '"UseLossConv:=", False');

[0125] output(file_out, '],');

[0126] output(file_out, '[');

[0127] output(file_out, '"NAME:RLDataBlock",');

[0128] output(file_out, '"MaxPass:=", 10,');

[0129] output(file_out, '"MinPass:=", 1,');

[0130] output(file_out, '"MinConvPass:=", 1,');

[0131] output(file_out, '"PerError:=", 1,');

[0132] output(file_out, '"PerRefine:=", 30,');

[0133] output(file_out, '"DataType:=", "RL",');

[0134] output(file_out, '"Included:=", True,');

[0135] output(file_out, '"UseParamConv:=", False,');

[0136] output(file_out, '"UseLossyParamConv:=", False,');

[0137] output(file_out, '"PerErrorParamConv:=", 1,');

[0138] output(file_out, '"UseLossConv:=", False');

[0139] output(file_out, ']');

[0140] output(file_out, ')');

[0141] It can be seen that in this embodiment, after the graphical interface information is configured, a series of configurations of the medium material properties need to be performed in the ANSYS software, and during the configuration process, there is no need to calculate the position and location information. After positioning each layer and generating the modeling script of the transmission line model, it is also necessary to configure the boundary of the transmission line model to isolate the transmission line model from the entire plane. After that, it is also necessary to automatically create the configuration information for the simulation analysis to perform the simulation analysis, realizing the automatic generation of the simulation environment based on the graphical interface in MATLAB, and finally automatically generating the Python script based on the MATLAB.

[0142] Referring to Figure 6 As shown, the embodiment of the present invention also correspondingly discloses a transmission line model building device, including:

[0145] A model building module 13, configured to generate a target modeling script for running on a finite element analysis software based on the modeling script, so as to build a model of the transmission line by using the target modeling script.
