Abstract

The invention discloses a wiring method of straight-line equal-width connection between two sets of ports in a layout. The wiring method is between circuit ports in the field of FPD design and EDA tools. The wiring method of the straight-line equal-width connection mode means connection between two ports through equal-width straight lines. Under the conditions that the space is wide and the resistance requirement for the wiring result is not strict, the direct wiring method between two sets of ports is a very practical method. The wiring method of straight-line equal-width connection can be adopted between two sets of parallel ports, between two sets of perpendicular ports as well as between two sets of ports at any angle only when each connection line meets the requirement of the minimum width and the interval between every two connection lines meets the minimum interval.

Description

The wiring method that in a kind of domain, between two groups of ports, the width such as straight line connects

Technical field

The wiring method directly connected between parallel port in domain is the wiring method between the circuit port in eda tool field.The invention belongs to flat-panel monitor design and EDA design tool field.

Background technology

Flat pannel display industry, referred to as FPD industry, is the emerging strategic industries of China.Flat pannel display industry is the foundation stone of the industry such as panel computer, TV, smart mobile phone flourish now, produces product and mainly contains liquid crystal panel, plasma panel and oled panel etc.From the angle of user, panel is exactly so-called display screen.

Region main in panel is pixel region, is also so-called viewing area.Still there are some non-display areas between four weeks of the viewing area glass edges to display screen place, can frame region be referred to as.Frame region carries a large amount of peripheral driver, control chip, and protection circuit etc.No matter being driving, control chip or protection circuit etc., is all the corresponding ports being connected to viewing area by the port of self.Therefore frame region also exists a large amount of wirings.Meanwhile, between chip port, also need wiring.

In general, port occurs all in groups, and such as viewing area port is arranged in order, and has certain intervals between every two ports.IC port also can occur in groups, is also have certain intervals between every two ports.So-called wiring refers to for two groups of ports according to Signal Matching rule, and match to two groups of ports one by one, the port having identical signal needs to link together with line figure.For design tool, need to carry out coupling wiring to hundreds of port, as shown in the figure simultaneously.

In general, often organize chip port and be all arranged in a linear, from the angle of coordinate, can be described as is roughly same level line or vertical curve arrangement.For convenience of description, the port claiming IC chip or viewing area is one group of port, as shown in the figure.If connected up between two groups of parallel ports, the wiring between two groups of parallel ports can be referred to as, as shown in the figure.Wiring between two groups of mutually perpendicular port set, can be referred to as the wiring between two groups of vertical ports, as shown in the figure.

Cloth line targets different during wiring can produce a very large impact the shape of wiring and result.Apart from each other at two row's ports, or during the resistance such as requirement, need to carry out resistance such as grades and connect up.Not far from one another at two row's ports, space is relatively loose, or time less demanding to routing resistance result, can carry out the wiring directly connected.

Summary of the invention

The present invention proposes to connect the method for carrying out connecting up by direct between a kind of two groups of parallel ports, comprises two groups of direct connecting wiring methods of parallel port direct connecting wiring method port vertical with two groups.

Two groups of direct connecting wirings of parallel port, as shown in Figure 1, match in order from two groups of ports, first port straight line of one group is connected to first port of other a group, second port straight line of one group is connected to second port of other a group, pairing like this, until connected all ports that can connect.A cardinal principle of sequence and pairing to produce crossing line, as shown in Figure 1.

Two groups of direct connecting wirings of vertical port, as shown in Figure 3, match in order from two groups of ports, first port straight line of one group is connected to first port of other a group, second port straight line of one group is connected to second port of other a group, pairing like this, until connected all ports that can connect.A cardinal principle of sequence and pairing to produce crossing line, as shown in Figure 3.

Minimum widith and minimum spacing rule must be met in wiring process.The minimum widith that so-called minimum widith rule refers to every root line can not be less than the width value of specifying.The minimum spacing rule spacing referred between adjacent two lines can not be less than the width value of specifying.

Concrete implementation step:

The method of direct wiring between parallel port is described in conjunction with a concrete example, and operating process step is as follows:

1) in AetherFPD instrument, start ERR order, in dialog box, input the parameter such as minimum feature and minimum spacing, and select straight line connection mode;

2) the both port of origination group of selective interconnection;

3) the terminating port group of selective interconnection;

4) hit OK button, completes wiring, and effect is shown in Fig. 1 or Fig. 3.
