Optionally, the electronic device performs comprehensive analysis and calculation on the routing length of each line segment to be analyzed in the line distance analysis table, performs total length verification on the hard disk wiring design, and compares the calculated result with the total length limit of the hard disk wiring design to obtain a total length verification result.
The electronic equipment comprehensively analyzes and calculates the wiring length of each line segment to be analyzed in the line distance analysis table, performs differential pair length verification on the hard disk wiring design, and compares the calculated result with the differential pair alignment requirement of the hard disk wiring design to obtain a differential pair length verification result.
The electronic equipment comprehensively analyzes and calculates the wiring length of each line segment to be analyzed in the line distance analysis table, performs binding group isometric verification on the hard disk wiring design, and compares the calculated result with the binding group alignment requirement of the hard disk wiring design to obtain a binding group isometric verification result.
In the embodiment of the invention, the hard disk wiring design is subjected to overall length verification, differential pair equal length verification and binding group equal length verification through the line distance analysis table, so that the hard disk wiring design is determined to be in accordance with the wiring specification, automatic checking of whether the hard disk wiring design is in accordance with the wiring specification can be realized, the checking time of checking personnel is reduced, and the checking efficiency is improved.
In some embodiments, the performing total length verification on the hard disk wiring design based on the routing length of each line segment to be analyzed in the line distance analysis table to obtain a total length verification result includes:
calculating the sum of the line lengths of the line segments to be analyzed to obtain a first length based on the line length of each line segment to be analyzed in the line distance analysis table;
and determining whether the first length meets the total length limit of the hard disk wiring design or not, and obtaining a total length verification result.
Optionally, the electronic device obtains the first length by performing summation operation on the routing lengths of the line segments to be analyzed in the line distance analysis table. The first length corresponds to the LT column in FIG. 3, and the respective numerical data in this column are obtained by summing the numerical data in the Dogbone column, the Breakout column, the Main _ sl _ or _ us1+ Main _ us 2 column, the Main _ us _3+ Main _us _ _4column, and the Breakin column for each high speed signal in the line distance analysis table. For example, the formula of the value corresponding to the LT column of the 20 th row is = SUM (C20: G20).
And the electronic equipment compares the first length with the total length limit of the hard disk wiring design, and determines whether the first length meets the total length limit of the hard disk wiring design or not to obtain a total length verification result.
The overall length constraint requirements for hard disk wiring design are determined by database, customer design requirements, or empirically. For example, the total length limit of a hard disk wiring design is required to be less than 8000 mils. If the first length is less than 8000mil, the display result of the target subcolumn under the Differential matching column in the line distance analysis table is PASS, which represents that the total length verification result is qualified, otherwise, the total length verification result is regarded as unqualified.
In the embodiment of the invention, the specific judgment mode of the hard disk wiring design meeting the total length verification in the wiring specification is determined, and whether the hard disk wiring design meets the total length requirement in the wiring specification can be intuitively judged through the target subcolumn under Differential routing in the wire spacing analysis table, so that the inspection efficiency is improved.
In some embodiments, the differential equal-length verification of the hard disk wiring design based on the routing length of each line segment to be analyzed in the line distance analysis table to obtain a differential equal-length verification result includes:
calculating the absolute value of the difference of the lengths of the differential pairs based on the routing length of each line segment to be analyzed in the line distance analysis table;
and determining whether the absolute value of the difference of the lengths of the differential pairs meets the alignment requirement of the differential pairs of the hard disk wiring design, and obtaining the verification result of the lengths of the differential pairs.
Optionally, serial signal buses such as SATA use differential signals, and due to the existence of factors such as pin distribution, via holes, and routing space, lengths of differential lines are not matched, timing sequences may shift, common mode interference may be introduced, and signal quality may be reduced. Correspondingly, the differential pair is compensated for the mismatch, so that the line lengths are matched, the length difference is usually controlled within 5mil, and the compensation principle is that where the length difference occurs, the compensation is performed; in order to ensure the signal quality of the differential signals, the wiring of the differential signal pairs generally requires equal length and impedance matching control according to the requirements of the bus specification.
And the electronic equipment performs absolute value operation on the difference of the lengths of the differential pairs on the wiring length of each line segment to be analyzed in the line distance analysis table to obtain an operation result of the absolute value operation on the difference of the lengths of the differential pairs. The Differential matching column in figure 3 includes a Tolerance sub-column and a target sub-column, each numerical data in Tolerance subcolumn is obtained by performing an absolute value operation of a difference between lengths of each Differential pair on numerical data in Dogbone column, brekout column, main _ sl _ or _ us1+ Main _ us _2 column, main _ us _3+ Main _us _ _4column, and breokin column in the line distance analysis table. For example, the Tolerance subcolumn value data in the Difference matching column at row 20 in FIG. 3 corresponds to the formula = IF (OR (ABS (H20-H21) > $ N $20, ABS (C20-C21) > $ N $20, ABS (D20 + E20-D21-E21) > $ N $20, ABS (F20-F21) > $ N $20, ABS (G20-G21) > $ N $ 20), "Notmatch", "OK"), where the value in $ N $20 is 2000.
The electronic equipment compares the operation result of the absolute value operation of the difference of the lengths of the differential pairs with the alignment requirement of the differential pairs of the hard disk wiring design, determines whether the operation result of the absolute value operation of the difference of the lengths of the differential pairs meets the alignment requirement of the differential pairs of the hard disk wiring design, and obtains a differential pair length verification result.
For example, the differential pair alignment requirement for hard disk wiring designs is greater than 2000 mils. If the operation result of the absolute value operation of the difference of the lengths of the differential pairs meets the requirement of being larger than 2000mil, the display result of the Tolerance subcolumn is OK, which represents that the equal length verification result of the differential pairs is qualified, otherwise, the display result of the Tolerance subcolumn is not matching, which represents that the equal length verification result of the differential pairs is unqualified.
In the embodiment of the invention, a specific judgment mode about the verification of the length of the difference pair in the hard disk wiring design meeting the wiring specification is defined, whether the hard disk wiring design meets the requirement of the difference pair alignment in the wiring specification can be intuitively judged through the display result of the Tolerance subcolumn under the Differential matching in the line spacing analysis table, and the inspection efficiency is improved.
In some embodiments, the performing, based on the routing length of each line segment to be analyzed in the line distance analysis table, a binding group isometric verification on the hard disk wiring design to obtain a binding group isometric verification result includes:
calculating the absolute value of the length difference of each binding group based on the routing length of each line segment to be analyzed in the line distance analysis table;
and determining whether the absolute value of the difference of the lengths of the binding groups meets the binding group alignment requirement of the hard disk wiring design or not, and obtaining the equal-length verification result of the binding groups.
Optionally, the electronic device performs an absolute value operation on the difference between the lengths of the binding groups on the trace length of each line segment to be analyzed in the line distance analysis table to obtain an operation result of the absolute value operation on the difference between the lengths of the binding groups. As shown in figure 3 where the Bundle matching column includes the Total distance sub-column and the Total distance sub-column, the numerical data in the Tolerance subcolumn are obtained by performing an absolute value operation on the difference between the lengths of the binding groups on the numerical data in the Dogbone column, the Breakout column, the Main _ sl _ or _ us1+ Main _ us _2 column, the Main _ us _3+ Main _us _ _4column and the Breakin column in the line distance analysis table. For example, the Tolerance subcolumn under the Bundle matching column corresponding to row 20 in FIG. 3 corresponds to the formula = ABS (H20-MIN (H $ 20. The Total clearance subcolumn under the Bundle matching column corresponding to row 20 in FIG. 3 corresponds to the formula = IF (OR (ABS (H20-H21) > $ N $20, ABS (C20-C21) > $ N $20, ABS (D20 + E20-D21-E21) > $ N $20, ABS (F20-F21) > $ N $20, ABS (G20-G21) > $ N $ 20), "Notmatch", "OK"), where the value in $ N $20 is 2000.
The electronic equipment compares the operation result of the absolute value operation of the difference of the lengths of the binding groups with the binding group alignment requirement of the hard disk wiring design, determines whether the operation result of the absolute value operation of the difference of the lengths of the binding groups meets the binding group alignment requirement of the hard disk wiring design, and obtains the equal-length verification result of the operation result of the absolute value operation of the difference of the lengths of the binding groups.
For example, the binding group alignment requirement for hard disk wiring designs is less than 200mils. The operation result of the absolute value operation of the length difference of each binding group corresponds to the numerical data in the Tolerance subcolumn under the Bundle matching column.
If the operation result of the absolute value operation of the difference of the lengths of the differential pairs meets less than 200mils, the verification result of the equal length of the differential pairs is qualified, otherwise, the verification result is not qualified.
In the embodiment of the invention, the specific judgment mode of the binding group equal-length verification in the condition that the hard disk wiring design meets the wiring specification is determined, whether the hard disk wiring design meets the binding group alignment requirement in the wiring specification or not can be intuitively judged through the display result of the Tolerance subcolumn under the Bundle matching in the line distance analysis table, and the inspection efficiency is improved.
