PCB design rule checker writing skills
Writing your own PCB design rule checker has many advantages. Although the PCB design checker is not that simple, it is not unattainable, because any PCB designer who is familiar with existing programming or scripting languages is fully capable of PCB design checker. The benefits of work are immeasurable.
However, general-purpose tools sold in the market often do not have enough flexibility to meet specific PCB design needs. Therefore, the customer must reflect the new feature requirements to the DRC tool developer, and this usually requires a certain amount of money and time, especially when the requirements are constantly updated. Fortunately, most tool developers can provide customers with a convenient way to write their own DRC to meet specific needs. However, this powerful tool has not yet been widely recognized or used. This article provides a practical guide for using DRC tools to get the most benefit.
Since DRC must traverse the entire circuit diagram of the PCB design, including each symbol, each pin, each net, and each attribute, an unlimited number of "attached" files can be created if necessary. As described in section 4.0, DRC can indicate any minor deviations that violate PCB design rules. For example, one of the attached files may include all decoupling capacitors used in PCB design. If the number of capacitors is lower or higher than the expected value, a red mark will be marked where the power line dv/dt problem may occur. These ancillary files may be necessary, but not any commercial DRC tool can necessarily create these files.
Another advantage of DRC is that it is easy to update to meet the needs of new PCB design features (such as those that may affect PCB design rules). Moreover, once you have gained sufficient experience in this field, many other functions can be achieved.
The above is the introduction of PCB design rule checker writing skills, Ipcb also provides PCB manufacturers and PCB manufacturing technology.
