Embodiment
A kind of method of setting up library file of the present invention, specifically refer to a kind of be used for printed circuit board software set up fast schematic diagram component symbol and PCB device package pin electrically between the method for corresponding relation library file.
The present invention sets up the process flow diagram of schematic diagram component symbol and the electrical corresponding relation library file of PCB device package pin fast as shown in Figure 3.
At first, in step S11, from the relevant database of company or according to the search file of an indexco.txt by name of associated documents output, contain schematic diagram component symbol information, electronic component physical package information and electron component characteristic information by computing machine in this file.Wherein, schematic diagram component symbol information comprises symbol coding, symbol schematic diagram title, and electronic component physical package information comprises symbol encapsulation title, and electron component characteristic information comprises information such as electric capacity, the capacitance etc. of other electronic components.It is pointed out that the information of this derivation comprises the title of certain symbol, and when this schematic diagram symbol file did not exist, for this kind situation, the present invention did not handle to it.
In step S12, need computing machine to generate the empty parts null file that is used to reflect corresponding information between symbol and cell pin, also can use existing library file, be used for the corresponding relation of follow-up foundation is write this parts file.
In step S13, will all be kept at the query directory of a computing machine from all schematic symbol symbol files (or being called schematic diagram component symbol file) that all departments collect, so that searching of symbol file conveniently realizes standardization.Usually, file name need be corresponding with the schematic symbol name information that database is derived, so that follow-up searching.
It should be noted that step S11, S12, S13 sequencing can have suitable variation, that is, S12 can finish before S11, also can finish after S13; Equally, S13 also can realize before S11.
