The embodiment of the application provides a winding layout method, which is applied to an integrated circuit chip. The main executing body of the winding layout method may be the winding layout device provided in the embodiment of the present application, or an integrated circuit chip integrated with the winding layout device, where the winding layout device may be implemented in a hardware or software manner, and the integrated circuit chip may be present in a device with processing capability and configured with a processor, such as a smart phone, a tablet computer, a palmtop computer, a notebook computer, or a desktop computer. The integrated circuit chip is capable of running a wire-routing layout tool, such as EDA (Electronic Design Automation) software.
Referring to fig. 1, fig. 1 is a first flowchart illustrating a winding layout method according to an embodiment of the present disclosure. The winding layout method may be run by the integrated circuit chip provided by the embodiment of the present application, and the winding layout method provided by the embodiment of the present application may include the following steps:
110, when the winding layout is performed in the winding channel, a macro-unit generation instruction is received.
In three layout design forms (Channel-based, Channel-less and Narrow-Channel) included in the layout design of the top layer at the rear end of the chip, most of the windings are arranged in the Channel-based, the Channel-less means that two modules are adjacent to each other, a winding Channel is not arranged between the two modules, and the Narrow-Channel is used for arranging some windings which are more critical between the two modules.
In the layout design, the processor obtains an initial winding layout and displays the initial winding layout in a user interface. Next, the processor executes a cell and winding resource estimation procedure based on the cell and winding resources of the initial winding layout, thereby obtaining a cell density and a winding density of the initial layout.
However, in the Channel-based layout design, many windings often pass through the winding Channel (i.e. Channel), and although an engineer usually reserves enough winding channels for the tool to perform automatic winding layout, the algorithm of the tool itself is to make the windings as short as possible under the condition of ensuring the winding.
For example, referring to fig. 2, fig. 2 is a first schematic winding layout diagram provided in the present embodiment, which illustrates a winding layout automatically performed by a tool according to an algorithm. In the layout design, taking 3 modules in a Full chip (Full chip) as an example, after the positions of the module a, the module B and the module C are distributed, a winding channel is arranged from the module a to the module B, the tool performs winding layout according to an algorithm, and Buffer cells (Buffer cells) are arranged on each winding at preset intervals. The buffer unit can increase the driving force of the winding wire, so that the transmission of signals in the winding wire is more stable.
According to fig. 2, the algorithm is based on the fact that the windings are as short as possible when the windings are passed through, so that the windings are concentrated in a narrow winding channel (for example, the windings in the figure are close to the module a and far away from the module C), the windings in the channel are longer, and therefore the interference between the windings is serious, and even the windings are not passed through, and most of the channels reserved by engineers are wasted.
Based on the method, the macro unit with reasonable layout can be generated in the winding channel to solve the problem. The macro unit is a predefined logic function realizing unit composed of a trigger with higher abstraction level relative to the logic gate, an arithmetic logic unit, a hardware register, etc. The logic cells are disposed as a macro cell in its entirety on a silicon wafer. Engineers implement different functions at higher logic levels by building metal interconnects in macro cells.

The macro cell generation instruction may be issued by a user or may be automatically generated by the integrated circuit chip.
In one embodiment, when performing winding layout in the winding channel, the ic chip first uses a tool to perform simulation winding layout, and detects a distance between windings in the winding channel after the tool completes simulation winding layout, and when detecting that the distance between two windings in the winding channel is smaller than a preset distance, the ic chip automatically generates the macro-unit generation command.
In one embodiment, when performing winding layout in the winding channel, the integrated circuit chip firstly uses a tool to perform simulation winding layout, detects crosstalk between windings in the winding channel after the tool completes simulation winding layout, and automatically generates the macro-unit generation instruction when monitoring that the crosstalk between two windings in the winding channel is greater than a preset crosstalk threshold.

And 120, determining winding parameters of the winding channel according to the macro unit generation instruction.
In order to ensure that the windings in the macro-cells are not crowded, the layout of the windings in the macro-cells needs to be reasonably planned. In one embodiment, after receiving the macro-unit generation instruction, the winding parameters of the winding channel are determined according to the macro-unit generation instruction, and then the macro-unit is generated in the winding channel according to the winding parameters.

The processor performs a unit and winding resource estimation procedure according to the unit resource and the winding resource of the initial winding layout, and estimates the number of windings to be laid in the winding channel. The channel length is the actual length of the winding channel.
In one embodiment, the width of the reserved channel corresponding to the routing channel is the width of the macro-cell to be generated. The width of the reserved channel corresponding to the winding channel is determined by the number of windings in the winding channel and the distance between the windings, for example, the width of the reserved channel is determined so that the distance between every two windings in the winding channel is larger than or equal to the preset distance.
Wherein, in order to reduce the negative effect that the wire winding overall arrangement in the wire winding passageway caused the product function, predetermine the interval and need confirm according to the actual demand of product to make the wire winding according to this predetermine interval overall arrangement can not cause the influence to the product function. For example, in order to make the influence of crosstalk between the windings on the timing less than or equal to 1ps (10)-12And second), determining a preset interval, and determining the width of a reserved channel corresponding to the winding channel according to the number of windings and the preset interval.
In an embodiment, determining a width of a reserved channel corresponding to the winding channel according to the number of windings and the preset interval includes: and taking the product of the number of the winding wires and the preset interval as the width of a reserved channel corresponding to the winding channel.

And because the winding layout is determined, before the layout design is finished, if the winding layout is carried out in the winding channel again, the macro cell can be directly generated in the winding channel again according to the determined winding parameters.
