Technical Field

The invention relates to the technical field of semiconductor integrated circuit design, in particular to a pixel unit classification recombination method in physical verification of a special-shaped flat panel display layout in the semiconductor integrated circuit design.

Background

Flat Panel Display (FPD) device, including cell-phone screen, computer Display, wrist-watch screen etc. wherein special-shaped Flat Panel Display device includes: the display unit comprises a mobile phone bang screen, a watch screen and the like, wherein a main body area of the mobile phone bang screen, the watch screen and the like is a display Pixel matrix (Pixel Array) positioned in the center of equipment and formed by arranging a large number of repeated circuit units (cells) in rows and columns, and a control circuit is usually arranged around the main body area.

In order to ensure the successful manufacture of the special-shaped flat panel display device, the special-shaped flat panel display circuit is also subjected to physical verification. Similar to the physical verification of the integrated circuit layout, the physical verification of the special-shaped flat panel display circuit layout includes Design Rule Check (DRC), Electrical appliance Rule Check (ERC), Netlist Extraction (NE), and the like. The coverage conditions of pixel units in different areas (such as edges and interiors) in the special-shaped layout are different, when layout Design Rule Checking (DRC) is carried out, various coverage graphs are applied to all the pixel units due to the fact that the pixel units of a pixel matrix are in an overlapping relation with an upper graph or the intervals between pixel unit examples are smaller than a certain value, some layout data are possibly promoted to an upper unit for calculation, a large number of repeated errors are caused, in order to guarantee efficient execution of physical verification of the special-shaped flat panel display circuit layout and avoid the problem that the error reporting result in the pixel units is promoted to the upper unit to cause a large number of repeated errors, the coverage graphs above all reference examples (instances) of the pixel units must be reasonably processed, the pixel units are classified and recombined according to the difference of the coverage graphs, and only one error reporting result of each category of pixel units is guaranteed, the designer can conveniently check and position the error position.

The existing physical layout verification tool does not reasonably process the covering graph above each pixel unit example of the FPD layout pixel array aiming at the layout characteristics of the special-shaped flat panel display circuit before verification and check. Then, the efficiency of execution of the verification check and the degree of duplication of the verification result are greatly affected. Optimally, the upper part of the pixel unit is not covered at all, the verification operation is carried out in the unit, the inspection result is also generated in the unit, and only one result of the full-page image is generated; in the worst case, if the reference instance of the pixel unit is covered by the reference instances of other units, the verification operation of the pixel unit can only be performed in the parent unit (usually, the top unit), and as many pixels as possible, the verification operation is performed as many times as possible, and the checking efficiency is extremely low. In an actual special-shaped panel display layout, metal wiring is mostly overlapped above a pixel matrix, and the number of results is expanded by thousands of times due to error reporting improvement, so that the verification efficiency is greatly influenced.

One prior art method is to check and remove repeated error reporting aiming at the design rule of a flat panel display layout, project the error reporting result in a projection unit from top to bottom to a pixel unit, cut an array into 9 parts, fix the number of the array cutting to 9 parts, remove repeated error reporting only aiming at the regular layout but not at the special-shaped layout, and have limitation; in another prior art, the layout is divided into a plurality of sub-regions by means of geometric isomorphism, an outer frame region is generated by isomorphism results, the checking results need to be counted and combined after the design rule checking is performed, the process is complicated, the layout is an mxn rule layout, and the method is not suitable for error repeat-removing and report of the abnormal-shaped board diagram design rule checking.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Fig. 1 is a flowchart of a physical verification method for an irregular flat panel display layout according to the present invention, and the following describes the physical verification method for the irregular flat panel display layout in detail with reference to fig. 1.

First, in step 101, a layout data file is input.

In step 102, the pixel units are classified and reorganized. In the step, the classification and recombination of the pixel units are realized before the pretreatment, the flow of the design rule check is not interfered, and the secondary calculation of the check result is not needed.

Preferably, the pixel units are classified, renaming each class of pixel units. In this step, renaming ensures that the overlap area of each type of pixel element does not contribute to the other types.

In this embodiment, the overlay graphics overlaid on all the instances of the input layout pixel unit are detected, the pixel units are classified, and the layers, the number, the shapes and the relative positions of the overlay graphics are specified to be completely the same as one another and to be in the same category.

In this embodiment, according to the classification result of the pixel units, each type of pixel unit is renamed according to the renaming rule: original pixel cell name + $ + number (1, 2, 3 …); the pixel cell names without graphic overlay remain unchanged as pixels, and the pixel cells with graphic overlay are named pixel $1, pixel $2 … in order according to the graphic category.

Preferably, all pixel cell matrices in the layout are broken up into 1 × 1 instances.

Preferably, the scattered pixel examples of each type are subjected to matrix recombination by using a pattern recognition algorithm, and a pixel unit matrix or example is output. In the step, the matrix recombination ensures the efficient execution of the subsequent layout preprocessing and design rule checking process, and has no influence on the algorithm flow.

In this embodiment, for a certain type of pixel instance, the specific recombination step includes:

a) and sorting all the examples according to the sequence of X and then Y, specifically sorting all the examples according to the coordinates of the lower left corner, and combining the sorting results into pixel column vectors.

b) The column vectors with identical contents and equal differences in the X direction are combined into a column matrix. All the column vectors with completely same contents record the equal difference value in the X direction as delta X, if the equal difference value in the X direction is met, the column vectors are accumulated and merged into a column matrix, and if the equal difference value in the X direction is not met, one matrix is restarted.

c) Decomposing the matrix into a plurality of pixel matrixes inside each column matrix according to the equal difference condition in the Y direction, and decomposing the combined result obtained in the step b), wherein the specific decomposition mode is as follows: and (3) identifying from the first example of the first row at the lower left corner by using a row unit, recording the Y-direction equal difference value as delta Y, decomposing row vectors which accord with the Y-direction equal difference value in the column matrix, restarting the matrix if the row vectors do not accord with the Y-direction equal difference value, and finally obtaining a plurality of pixel matrixes after the decomposition.

d) A collection of scattered instances was performed.

e) The resulting matrices or instances of the outputs.

In step 103, the layout file is preprocessed to perform layout level adjustment.

In step 104, in order to perform design rule checking according to a general hierarchical processing method, error reporting results of each type of pixel unit (including pixel units with or without graphic coverage) are calculated and counted. In the step, the subsequent layout preprocessing and design rule checking process is carried out according to the original level processing method, and the error reporting result does not need to be additionally processed.

In step 105, a design rule check result file is output.

In the embodiment, a large amount of repeated errors caused by overlapping graphs above the pixel unit example are eliminated in a mode of classifying and renaming the pixel units; if verification and inspection are directly carried out in scattered pixel units, the efficiency is low due to large workload, and the significance of realizing pixel instance recombination by applying the repetitive pattern recognition algorithm is that only one error report result is provided for each type of pixel unit when design rule inspection is carried out, so that the layout preprocessing and design rule inspection processes are accelerated, and the layout verification efficiency is greatly improved.

The method for physically verifying the special-shaped flat panel display layout is further described below with reference to a specific embodiment.

Fig. 2 is a flowchart of a pixel unit classification and reorganization method in a flat panel display layout physical verification according to an embodiment of the present invention.

First, in step 201, pixel units are classified, specifically implemented as: detecting overlapped graphs above examples of all pixel units in the layout, classifying the data of the whole layout, defining a reference matrix of the same subunit, considering the data as different categories if the unit rotation direction is different or the horizontal/vertical direction spacing and the number of the matrix are different, and determining the classification result according to the layout data and classifying the classification result into a plurality of categories.

In step 202, renaming each category of pixel units (including pixel units with or without graphic coverage) according to the detection result of step 201, wherein the renaming rule is as follows: original pixel cell name + $ + number (1, 2, 3 …); wherein the pixel cells not covered by the graphics are sub pixels, and the pixel cells with the graphics covering are renamed to pixel $1 and pixel $2 … in sequence according to the graphics category.

In step 203, all pixel unit matrixes in the layout are scattered, wherein the scattering is a 1 × 1 example.

Steps 204 to 209 show the process of performing repeated pattern recognition on all 1 × 1 instances in the layout, which includes the following steps: sorting by X and Y, calculating a Hash value, combining equal difference column vectors into a column matrix, decomposing the column matrix into a plurality of pixel matrixes, collecting scattered examples, and outputting a pixel unit matrix or an example:

in step 204, the scattered 1 × 1 instances are sorted by X and then Y according to the coordinates of the lower left corner of the graph, the instances are sorted according to the coordinates of the lower left corner, and the sorting results are combined into a pixel column vector.

Steps 206 to 208 show the whole process of pixel instance reorganization of the decomposed isobarical column segments, which includes the following steps: merging the equal-difference column vectors into a column matrix, decomposing the column matrix into a plurality of pixel matrices, and collecting scattered examples.

First, at step 206, the arithmetic column matrix is merged to merge all the column vectors that are identical in content and arithmetic in the X direction. Wherein reference matrixes of the same subunit are defined, and if the rotation directions of the units are different or the horizontal/vertical direction intervals and the number of the matrixes are different, the matrixes are considered to be in different categories. All the column vectors with completely same contents record the equal difference value in the X direction as delta X, if the equal difference value in the X direction is met, the column vectors are accumulated and merged into a column matrix, and if the equal difference value in the X direction is not met, one matrix is restarted.

Step 207, decomposing the column matrix into a plurality of pixel unit matrices, decomposing the column matrix into a plurality of pixel matrices according to the equal difference condition in the Y direction inside each column matrix, and decomposing according to the merging result obtained in step 206, wherein the specific decomposition mode is as follows: and (3) identifying from the first example of the first row at the lower left corner by using a row unit, recording the Y-direction equal difference value as delta Y, decomposing row vectors which accord with the Y-direction equal difference value in the column matrix, restarting the matrix if the row vectors do not accord with the Y-direction equal difference value, and finally obtaining a plurality of pixel matrixes after the decomposition.

In step 208, if a stray instance exists, a collection of stray instances is performed.

Step 209 outputs the pixel cell matrix or instance and the repetitive pattern recognition ends.

Through a series of steps of the method, the classification pixel unit renames each type of pixel unit, and only one verification operation result of each type of pixel unit is ensured after the pixel unit matrix is scattered, so that the number of repeated error reporting is greatly reduced; the method is completed before the preprocessing process, the subsequent design rule checking process is not influenced, the checking result can be directly output without additional calculation, and the physical verification efficiency is improved.
