It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The following describes embodiments of the present application in detail.
Referring to fig. 1, fig. 1 is a schematic flow chart of a simulation method provided in an embodiment of the present application, and is applied to a simulation device, where the simulation device is installed with a first simulation software, as shown in the figure, the simulation method includes:
s101, inputting a LAYOUT composition design drawing and a judgment standard;
the LAYOUT design drawing of the LAYOUT design can be the LAYOUT design drawing of the LAYOUT design in various formats, and can be called through an interface provided by the TCK/TK. The decision criterion includes R and L values that should be satisfied at 0 to 1GHz, and the format of the decision criterion may include a plurality of formats.
S102, converting the format of the LAYOUT composition design drawing into a preset format to obtain an identifiable drawing;
the LAYOUT file has more design software and different file formats output by various software, so that the module calls an interface of simulation software to convert an input LAYOUT composition design drawing and outputs an identifiable drawing.
In the specific implementation, the suffix name of the input LAYOUT composition design drawing is read first, for example, brd of' simulation. Then recognizing the read suffix name of the LAYOUT composition design drawing, and calling a corresponding module through tcl language, wherein the corresponding module is a module of the simulation software; for example, a call can convert a brd file into a recognizable SPD file, and the syntax mode is "transformxxx.brdxxx.spd"; or calling the SPD file which can convert the pcb file into a recognizable SPD file, wherein the syntax mode is 'transformxxx.brdxxx.spd'; or calling the recognizable SPD file capable of converting the odb file into the recognizable SPD file, wherein the syntax mode is 'transformxxx.brdxxx.spd'; and finally, storing the output recognizable drawing in a directory at the same position as the input LAYOUT composition design drawing.
S103, calling the first simulation software to simulate the recognizable drawing to obtain a simulation result, and outputting a first R value and a first L value, wherein the first R value is used for representing a resistance value of the recognizable drawing under a preset frequency band, and the first L value is used for representing an inductance value of the recognizable drawing under the preset frequency band;
the first simulation software is simulation software which can be supported by TCL/TK language, the design of the recognizable drawing output by the S102 is simulated by the first simulation software, and R and L values under 0-1 GHz are output.
S104, comparing the first R value and the first L value with a second R value and a second L value in the judgment standard to obtain a judgment result;
and when the R and L values at 0-1 GHz output in S103 are larger than the R and L values contained in the judgment standard, the LAYOUT composition design drawing does not meet the requirement.
And S105, generating a simulation report according to the judgment result, and outputting the simulation report.
The values of R and L at 0 to 1GHz output in S103 and the values of R and L included in the decision criteria are plotted as a curve and output, the curve is represented by frequency and abscissa, the amplitudes of R and L are ordinate, and the simulation report includes the curve.
The output mode includes, but is not limited to, directly outputting the simulation report, importing the simulation report into the cloud, and outputting the simulation result in the SNP format.
In the specific implementation, the problem that the capacity of a local workstation is limited and the data protection function is insufficient is solved. By calling a TCP/IP interface of the TCL, the result obtained by simulation is automatically compressed according to a naming mode of date-time-network name and then uploaded to the cloud server, so that data archiving and data protection are facilitated. In order to solve the problem that the simulation result needs to be post-processed, the simulation result is output in the form of an S parameter matrix, and the result can be called and processed by common simulation software or data processing software.
It can be seen that, in the embodiment of the application, the emulation device firstly inputs the LAYOUT drawing of the LAYOUT composition and the judgment standard; converting the format of the LAYOUT composition design drawing into a preset format to obtain an identifiable drawing; then calling first simulation software to simulate the recognizable drawing to obtain a simulation result, and outputting a first R value and a first L value, wherein the first R value is used for representing the resistance value of the recognizable drawing under the preset frequency band, and the first L value is used for representing the inductance value of the recognizable drawing under the preset frequency band; secondly, comparing the first R value and the first L value with a second R value and a second L value in a judgment standard to obtain a judgment result; and finally, generating a simulation report according to the judgment result and outputting the simulation report. Therefore, the LAYOUT composition design drawing and the judgment standard are input by the simulation equipment, the LAYOUT composition design drawing is converted and simulated, the LAYOUT composition design drawing is compared with the judgment standard, and the simulation report of the LAYOUT composition design drawing is output, so that the automatic simulation and error detection optimization of the LAYOUT composition design drawing are realized, the automatic simulation is performed on the simulation equipment to replace the manual experiment and simulation of an engineer, and a large amount of time and production cost are saved. And the lack of experience of engineers or the occurrence of wrong simulation is avoided, and the efficiency and the accuracy are improved.
In one possible example, after invoking the first simulation software to simulate the recognizable drawing to obtain a simulation result and outputting a first R value and a first L value, the method further includes: obtaining a first frequency domain curve of the simulation result through a preset circuit; after inputting the LAYOUT drawing of the LAYOUT and the decision criteria, the method further comprises: obtaining a second frequency domain curve of the judgment standard through the preset circuit; and comparing the first frequency domain curve with the second frequency domain curve to obtain and output a comparison result.
Because the comparison of the R, L, and C values is not intuitive, the R, L, and C values are substituted into the circuit of fig. 7, a frequency domain curve of the circuit is obtained through frequency domain simulation, the curve is used as a decision index, the abscissa of the curve is frequency, and the ordinate is impedance z. Substituting the RLC value of the LAYOUT composition design drawing into the circuit of the figure 7 to obtain a first frequency domain curve; the value of the RLC of the decision criterion is substituted into the circuit of fig. 7 to obtain a second frequency domain curve.
It can be seen that, in this example, the simulation equipment can obtain a first frequency domain curve and a second frequency domain curve based on a preset circuit, the RLC value of the LAYOUT composition design drawing and the RLC value of the judgment standard, compare the first frequency domain curve and the second frequency domain curve, and obtaining and outputting a comparison result, so that the difference between the RLC value of the LAYOUT composition design drawing and the RLC value of the judgment standard can be more visually and vividly displayed, and whether the RLC value of the LAYOUT composition design drawing meets the requirement or not is conveniently judged.
In one possible example, after the decision criterion is input, the method further comprises: acquiring a frequency band value of the judgment standard; and expanding the frequency band value to a preset frequency band value.
The input judgment standard may be a value at a certain frequency point or a certain frequency band, and the full-band expansion is performed on the input judgment standard by using Z = R +2 Π fL
It can be seen that, in this example, the emulation device is capable of extending the decision criteria based on their frequency band values, the method is favorable for comparing and judging the LAYOUT composition design drawing and the judgment standard under the same frequency band, and is favorable for optimizing the LAYOUT composition design drawing.
In one possible example, after inputting the LAYOUT drawing and the decision criterion, the method further includes: identifying a capacitance parameter in the LAYOUT composition design drawing; calling a first preset device model according to the capacitance parameter; importing the preset device library into preset simulation software for simulation calculation; judging whether the simulation calculation is converged; and when the simulation calculation is not converged, equivalently converting the first preset device model into a second preset device model.
The capacitance parameters comprise the bit number, the packaging and the capacitance value of the capacitor. The first pre-set device model may be, but is not limited to, an S2P file, and the second pre-set device model may be, but is not limited to, an RLC model.
In specific implementation, the simulation device identifies the bit number, package and capacitance value of the capacitor contained in the inputted LAYOUT drawing, and then calls a corresponding S2P file (the file is the model of the device). When the first simulation software is used for simulation calculation, the problem of non-convergence is easy to occur, and when the simulation calculation is not converged, the first simulation software outputs simulation non-convergence information, converts the S2P file into an equivalent RLC model, and then inputs the equivalent RLC model into the first simulation software for simulation calculation.
It can be seen that, in this example, the simulation apparatus is able to pattern a first preset device model of the capacitance in the design drawing based on LAYOUT, and equivalent conversion is carried out when the simulation is not converged, so that the correctness and the effectiveness of the simulation calculation are ensured.
In one possible example, after converting the format of the LAYOUT design drawing of the LAYOUT design into a preset format to obtain a recognizable drawing, the method further includes: identifying passive devices in the identifiable drawing; reading the category, the value and the package of the passive device; searching a preset model corresponding to the passive device in a prestored passive device library; and importing the passive device library into the preset simulation software for simulation calculation.
The output identifiable drawing comprises a plurality of passive devices, each passive device comprises a resistor, a capacitor and an inductor, and each passive device comprises a bit number, a value and a package. For example, for a resistor, the bit number of the resistor, such as R1; the resistance of the resistor, e.g., 1Kohm; encapsulation of resistors, such as 0201; the function of the module is to package and arrange the passive elements according to categories (resistance, capacitance, inductance, respectively beginning with R, C, L), bit numbers, values, and then output a list. Reading the passive devices in the output list, and firstly reading the types, such as capacitance, inductance or resistance; then read the value, e.g., 1Kohm; the package is then read, e.g., 0402. The model (SNP format) of the device is then looked up in the archived library in full contrast to the above three subclasses, and the library is then imported into the simulation calculation in TCL language through the interface reserved by the software.
Therefore, in the example, the simulation equipment can call the corresponding passive device library through the category and the numerical value of the passive device in the recognizable drawing and packaging, so that the simulation calculation is facilitated to call the passive device in the recognizable drawing corresponding to the passive device library, and the simulation process is faster and more accurate.
In one possible example, before invoking the first simulation software to simulate the recognizable drawing to obtain a simulation result and outputting the first R value and the first L value, the method further includes: inputting a schematic diagram; comparing the schematic diagram with the LAYOUT composition design drawing, and converting the format of the schematic diagram into a preset format to obtain an identifiable schematic diagram; or, inputting the lamination information; comparing the lamination information with the LAYOUT composition design drawing, and converting the format of the lamination information into a preset format to obtain identifiable lamination information; or, inputting a bill of materials; comparing the bill of materials with the LAYOUT composition design drawing, and converting the format of the bill of materials into a preset format to obtain an identifiable bill of materials; or, a list of input ports; and comparing the port list with the LAYOUT composition design drawing, and converting the format of the port list into a preset format to obtain an identifiable port list.
The schematic diagrams output by various design software are input, and are cross-compared with the input LAYOUT composition design drawing, and whether the LAYOUT composition design drawing is consistent with the schematic diagram version number is checked.
Inputting the information of the actually processed lamination, and cross-comparing the information with the inputted LAYOUT composition design drawing, wherein the module checks whether the metal thickness and the medium thickness of each layer in the lamination are consistent with the LAYOUT composition design drawing, and checks whether the LAYOUT composition design drawing adopts the final lamination design.
The statistical material information is input and is cross-compared with an input LAYOUT composition design drawing, the module is mainly used for checking whether devices such as a chip, a resistor, a capacitor, an inductor and the like in the LAYOUT composition design drawing are complete, and the module can be used for checking whether the LAYOUT composition design drawing is consistent with the material information of a schematic diagram.
Inputting a port list provided by a chip supplier, wherein the port is a pin number of a chip which the port should contain, a pin connected with a power supply is a positive terminal, a pin connected with a ground network is a negative terminal, and cross-comparing the pin with an input LAYOUT composition design drawing, mainly checking whether the positive terminal and the negative terminal in the port are consistent, and the module can check whether the ports of the LAYOUT composition design drawing are complete.
It can be seen that, in this example, the simulation device enters a schematic diagram, overlay information and port list, and the LAYOUT picture composition design drawing is compared with the LAYOUT picture composition design drawing, so that the correctness of the LAYOUT picture composition design drawing can be detected, and the error probability is reduced.
In one possible example, after inputting the overlay information, the method further comprises: calculating the parasitic capacitance of the lamination information; and obtaining a capacitance value in a preset frequency band, comparing the capacitance value with the capacitance value in the same frequency band in the judgment standard, judging whether the parasitic capacitance meets the requirement and outputting the capacitance.
Calculating parasitic capacitance of two power plane layers in the laminated information, acquiring capacitance values within 10 MHz-200 MHz, outputting and comparing with the value of the frequency in the judgment standard, and if the value of the parasitic capacitance is larger than the value of the input judgment standard, the requirement is met.
Therefore, in this example, the simulation device may determine whether the value of the parasitic capacitance in the stack information meets the requirement based on the capacitance values of the parasitic capacitances of the two power plane layers in the stack information, thereby improving the efficiency and accuracy of the simulation calculation.
In one possible example, after the bill of materials is input, the method further comprises: calculating a first impedance value of a capacitor in the bill of materials under a preset frequency band; and comparing the first impedance value with a second impedance value of the capacitor in the judgment standard, judging whether the capacitor in the bill of materials meets the requirement or not, and outputting the result.
The impedance of the capacitor contained in the bill of materials under a preset frequency band is calculated, wherein the preset frequency band can be a weight frequency band of 0-1 GHz and can also be any frequency band value. And reading the capacitance in the bill of materials, calculating the value of the partial capacitance under the frequency band of 0-1 GHz, comparing the value with the value of the capacitance in the input judgment standard, and if the value is larger than the capacitance of the standard, meeting the requirement.
Therefore, in this example, the simulation device may compare the impedance value in the preset frequency band of the capacitor in the bill of material with the impedance value of the capacitor in the decision criterion, and determine whether the capacitor in the bill of material meets the requirement, so as to improve the efficiency and accuracy of the simulation calculation.
In one possible example, after the input port list, the method further includes: and calculating and outputting the via holes required to be added by each pin in the port list.
In specific implementation, when the direct current resistance is met, calculating the via hole to be added to each pin in the terminal, dividing the direct current in the input judgment standard by 0.3 according to the current carrying capacity of 0.3A/hole to obtain the number of all the required via holes, and dividing the number of the via holes by the number of pins contained in the terminal list to obtain the via hole to be added to each pin.
Therefore, in this example, the simulation device may calculate the via hole that should be added to each pin in the port based on the port list, so as to improve the efficiency and accuracy of the simulation calculation.
