Definitions
- a bypass capacitor inserted between the power supply terminal and the GND terminal of a digital IC compensates for the high-frequency fluctuation of the power supply voltage generated by the switching operation of the IC with the stored electric charges, and stabilizes the high-frequency component. It is widely known as the most basic and important item in the countermeasures for unnecessary radiation noise of circuit boards because it plays a role of confining high-frequency noise around the IC by returning it to the GND terminal of the A printed circuit board design device using many methods and tools related to lines has been proposed.
- the layout position and wiring route of the bypass capacitor, etc. are determined at random within the range of human power ⁇ ⁇ within the range that adheres to the design rules, so the EMC design quality depends on the pattern designer and varies with the design quality. There was a problem.
- the present invention provides a printed circuit board design without a design quality difference by a pattern designer. It is an object of the present invention to provide a possible printed circuit board design method, a printed circuit board design device, and a CAD system.
- FIG. 9 is a plan view showing an example of an optimum arrangement position display in the embodiment (arrangement angle 0 °).
- step S3 an arrangement / wiring area of the EMC countermeasure component is calculated based on the basic configuration and the basic pattern determined in step S1 and step S2. Specifically, the areas determined in Step Sl and Step S2, excluding the area where the large-scale IC, the medium-scale IC, the connectors (terminals), and the IC peripheral circuit components are closed, and the area where the wiring pattern is formed are excluded. , Placement of EMC countermeasure components ⁇ Calculated as the area where wiring is possible. [0017] Step S4.
- step S9 the EMC components are provisionally placed at the placement candidate points set in step S8 so that their centers coincide with the candidate points.
- the candidate points that fit are extracted (candidate points are narrowed down), and the EMC component is placed at one of the narrowed placement candidate points.
- step S10 the necessary wiring is performed on the EMC component arranged in step S9.
- the margin amount is a margin in design rules and mounting restrictions. For example, with regard to the arrangement distance of item 1 in Table 1, if the distance between the IC power supply terminal and the capacitor is 16 mm, the margin amount is 4 mm for the condition of 20 mm or less. In terms of the placement prohibited range, if the IC end force is also the distance from the EMC countermeasure component, if the force S is 15 mm, if the IC is placed within 10 mm, the margin for the !!, Kena! /, And! / The amount will be 5mm.
- step S15 and step S16 are further repeated.
- the difference between the design value and the pass / fail judgment value is determined by the marker. Gin value.
