Method and System for Providing Printed Circuit Board Design Software and Tools Linked with Design Documents through a Design Database

Disclosed is a method and system for providing Printed Circuit Board (PCB) design software and tools linked with design documents through a design database. The method and system creates a special database to link a schematic and the design documents dynamically, thereby, enabling one or more of hardware designers, test engineers and layout engineers to read the schematic easily.

Fig. 1 illustrates a block diagram to show the linkage of the schematic and the design database.

Figure 1

As shown in fig. 1, the schematic includes, but is not limited to, design files in a schematic capture tool or schematic files, schematic sheets, block diagrams and multiple components. Here, the multiple components include, but are not limited to,

Application Specific Integrated Circuit (ASIC), clock Oscillator (OSC), DC- DC converter, ferrite beads, resistors and capacitors. The schematic also includes signal nets and topology of the signal nets. As shown in fig. 1, the design database is utilized to

either link files or store files directly. The design database stores design documents, such as, but not limited to, text files, pictures, waveforms, simulation files and information related to schematic capture and layout guides. The design database also stores a PCB board or a system level design specification, a components data sheet, a pin description and other requirements such as, but not limited to, clock frequency, jitter and bandwidth. Further, the design database includes design guides for both the schematic capture and layout. The schematic capture and layout is performed for one or more of an ASIC such as, but not limited to, a Central Processing Unit (CPU) and an Ethernet switch, a clock such as, but not limited to, OSC and buffers and power modules such as, but not limited to, AC-DC converter and DC-DC converter. In addition, the design database includes technique notes on a device pin or a signal net topology during the schematic capture or design review.

Fig. 2 illustrates a screen shot of a window for inserting files to the design database.

Whenever a new schematic is captured or the schematic is updated on a schematic capture window, then the design documents are attached to a component or a pin on an attributes window. This information is then...
