Abstract
The invention provides a method and system for quickly drawing wiring prohibition areas around differential-signal via holes, and belongs to the electronic field. The method comprises the following steps that a program of the wiring prohibition areas around the differential-signal via holes is written; the program of the wiring prohibition areas around the differential-signal via holes is executed, and offset values are input so that positioning of the wiring prohibition areas around the differential-signal via holes can be completed. According to implementation of the technical scheme, addition of the wiring prohibition areas can be achieved as long as one command is operated and can be completed through only one key. Through the written SKILL program, the method for adding the wiring prohibition areas easily, conveniently and quickly is achieved, the amount of computation of wiring areas and coordinates for wiring designers is reduced, and the work efficiency of the wiring designers is greatly improved.
Description
Technical field
The present invention relates to electronic applications, relate in particular to a kind of method and system that differential signal via hole is prohibited cloth region around that draw fast.
Background technology
At present, the CADENCE ALLEGRO wiring design software of using for us, with respect to other wiring design software, very powerful of function, but along with increasing of signal rate, signal integrity is even more important, and in order to reduce the stray inductance effect of high speed signal via hole, we require in differential signal via hole certain limit, to be set to prohibit cloth region; With CADENCE ALLEGRO traditional method, be according to crossing hole site and size, and wiring need to be away from the distance of via hole, calculate size and the position of prohibiting cloth region, under the trend of Project design cycle shortening, need to reduce as much as possible wires design person's working time.
But while doing some larger pcb boards, in the more situation of high speed signal, use traditional method for designing, PCB designer need to expend the long period and prohibits the size in cloth region and position calculation and easily make a fault, and the design cycle also will be elongated.
Summary of the invention
The invention provides a kind of method and system that differential signal via hole is prohibited cloth region around that draw fast, to address the above problem.
The invention provides a kind of method that differential signal via hole is prohibited cloth region around that draws fast.Said method comprises the following steps:
Write differential signal via hole and prohibit cloth region program around;
Carry out described differential signal via hole and prohibit cloth region program around, input offset numerical quantity, completes the location that differential signal via hole is prohibited cloth region around.
The present invention also provides a kind of system that differential signal via hole is prohibited cloth region around that draws fast, comprising: write module, locating module; The described module of writing is directly connected with described locating module;
The described module of writing, prohibits cloth region program around for writing differential signal via hole;
Described locating module, prohibits cloth region program around for carrying out described differential signal via hole, and input offset numerical quantity, completes the location that differential signal via hole is prohibited cloth region around.
By implementing technical scheme of the present invention, only need to operate an instruction and just can realize the interpolation of prohibiting cloth region, a key just can complete; By the SKILL program of writing, realized the method that cloth region is prohibited in simple, fast interpolation, reduced the calculating of wires design personnel for wiring region and coordinate, greatly improved wires design personnel's work efficiency.
