Definitions
- the present invention relates to the field of power integrity simulation technologies, and in particular, to an ODB++ file modification method, apparatus, and readable storage medium.
- ODB++ is an extensible ASCII format that preserves all engineering data necessary for PCB manufacturing and assembly in a single database.
- a single file can contain graphics, drill information, wiring, components, netlists, specifications, drawings, engineering process definitions, reporting functions, ECO and DFM results. Operators can improve and correct DFM to update their original CAD database and try to identify all cabling issues before the design reaches the assembly phase.
- ODB++ is a two-way format that allows data to be uplinked and downlinked.
- the ODB++ database is similar to the database for most CAD systems. Once the data arrives at the board shop in ASCII, the producer can perform value-added process operations such as etch compensation, panel imaging and output drilling, routing, and photography.
- Power Integrity is a stable and reliable power distribution system (PDS) for board-level systems.
- PDS power distribution system
- the power supply and ground noise are effectively controlled when the system is in operation, and the chip is provided with sufficient energy in a wide frequency band, and the voltage fluctuation, radiation and crosstalk caused by the chip operation are sufficiently suppressed.
- the ODB++ standard (which is a format favored by manufacturing) has emerged. Since this file is a standard public format, it can be used as a standard on the market. EDA software is an output interface standard. Different EDA software can be solved after the introduction of ODB++ with copper and via defects. However, since it is a standard for PCB processing documents, the electrical properties of the components (such as the model name of the capacitor and the capacitor package name) are transferred. Due to the differences in the design of different PCB design software and the irregularity of the design, there may be problems. In this case, if the ODB++ file is transferred to the electrical properties, the original PCB file is not modified or essential in the original EDA software. It is feasible.
- the corresponding PCB design file needs to be transferred.
- the capacitor The value or package of the resistor or inductor may not be adjusted or the format is incorrect (for example, the PCB design file provided by the customer is not standardized due to internal definition, etc.
- the default model may be the same name---encapsulation The name of the shape, but the actual component library model is different), or the model name of the component is unrecognizable, which requires manual processing later. The processing can be processed separately according to the actual simulation model of the capacitor or the corresponding value. It can be very time consuming and error prone.
- an object of the present invention is to provide a method for modifying an ODB++ file.
- the modified ODB++ file is applicable to all PCB PI simulation platforms, and is convenient to use and high in efficiency.
