Abstract

PURPOSE:To process in real time a wiring job of a large-scale/multi-layer substrate having high density by dividing a substrate into areas and forming a wiring section over these divided areas in 1/N (N>=1) of an allowable wiring grating. CONSTITUTION:A wiring job is carried out between two points connected to each other in a wiring design mode by setting a wiring grating for wiring processing on a substrate. In this case, the substrate is divided into an optional number of areas by an area dividing means 4. An inter-area wiring means 5 uses only the wiring grating of 1/N (N>=1) allowable wiring grating to perform a wiring job for section among those divided areas. An intra-area wiring means 6 performs wiring jobs in wiring sections in each area by means of the allowable wiring grating. In such a constitution, the handling data quantity is never limited and the wiring processing can be attained in real time with a large-scale/multi- layer substrate having high density despite increase of the number of wiring sections and wiring gratings.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a wiring processing method in wiring design for printed wiring boards, ceramic wiring boards, and the like.

[Conventional technology]

Conventionally, in this type of wiring processing method, a wiring grid for wiring processing is set on a board, and wiring processing between two points to be connected (hereinafter referred to as a wiring section) is performed on the entire board.

[Problem that the invention seeks to solve]

The conventional wiring processing method mentioned above has become more dense in recent years.

In the case of wiring processing for highly multi-layered and large-scale boards, due to the increase in the number of wiring sections and wiring grids, wiring processing cannot be performed due to scale constraints on the amount of data that can be handled, or wiring processing cannot be completed in real time. There were some drawbacks.

[Means for solving problems]

The wiring processing method of the present invention divides the board into regions, and divides the wiring section spanning K between the regions to 1/N (however, N
≧1).

[Effect]

The present invention can perform wiring processing for high-density, high-multilayer, and large-scale boards in real time.

〔Example〕

The figure is a block diagram showing an embodiment of the wiring processing method according to the present invention. In the figure, 1 and 2 are wiring section data and fault data such as wiring section, board size, number of layers, various wiring prohibitions, minimum wiring grid, etc. that are input for wiring processing, and 3 is control data when performing split wiring processing. division instruction data, 4 is a region dividing means for dividing the board into an arbitrary number of regions, and 5 is only a wiring grid of 1/N (however, N≧1) of the wiring grid that allows wiring in the wiring section spanning between each region. 6 is an intra-region wiring means for wiring the wiring sections in each region in units of each region using an allowable wiring grid; T is the output of the wiring process; , is wiring data indicating a wiring axis path for each wiring section.

Next, the operation of the wiring processing method with the above configuration will be explained. First, the region dividing means 4 classifies the wiring section data 1 and the fault data 2 into divided regions according to the division instruction data 3 which is control data. At this time, the wiring section data that spans between areas is classified into one category, and the wiring grid used when wiring the wiring section that spans between these areas is set to 1/N of the allowable wiring grid (however, N≧1). Divide the wiring grid conversion instruction data to
For this reason, failure data related to the wiring grid used in inter-area wiring processing is also classified into one category. Next, the inter-area wiring means 5 targets only the inter-area wiring sections and the corresponding failure data from the data classified by the area dividing means 4, using only the wiring grid indicated by the wiring grid conversion instruction data. , performs wiring processing for wiring sections spanning between regions. The wiring peak road data for this wiring section is the wiring data T
Output to. The obtained distribution route data is then classified into divided areas, and new failure data is added to the failure data classified into each area. next,
The intra-area wiring means 6 targets the remaining data classified by the area dividing means 4, that is, each intra-area wiring section and the corresponding failure data, and performs wiring processing on the intra-area wiring sections for each area, and determines the permissible wiring. Do this using a grid. Then, by outputting the wiring route data for the wiring section as the wiring data T), wiring processing can be performed in real time.

〔Effect of the invention〕

As explained in detail above, according to the wiring processing method according to the present invention, the board is divided into regions, and the wiring section spanning K between the regions is performed at 1/N (however, N≧1) of the allowable wiring grid. Large scale, high multilayer.

This has the effect of making it possible to process wiring on high-density boards in real time.
