PCB Design: How to Reduce Errors and Improve Efficiency

Circuit board design is a critical and time-consuming task, and any issues that arise require engineers to inspect the entire design network by network and component by component. It can be said that the level of attention required for circuit board design is no less than that of chip design.

The typical circuit board design process consists of the following steps:

The first three steps take the most time because schematic inspection is a manual process. Imagine a SoC circuit board with 1000 or even more connections. Manually checking every connection is a tedious and tedious task. In fact, checking every connection is almost impossible, which can lead to problems with the final circuit board, such as incorrect connections, floating nodes, etc.

The schematic capture phase generally faces the following types of problems:

● Incorrect underline: such as APLLVDD and APLL_VDD

● Case issues: such as VDDE and vdde

● Spelling errors

● Signal short circuit problem

●... There are many more

To avoid these errors, there should be a way to check the entire schematic in a few seconds. This method can be implemented through schematic simulation, which is rarely seen in the current circuit board design process. Through schematic simulation, the final output result can be observed at the required nodes, so it can automatically check all connection issues.
