Circuit board design is a key and time consuming task, any questions are need to check the whole design engineer one by one network element.Can say careful degree as chip design of PCB design requirements.

The typical circuit board design process is composed of the following steps:

pcb design 01

Spend most time in front of the three steps, because the check is a manual process schematic diagram.Imagine a SoC circuit board with 1000 or more connections.Artificial check every connection is a tedious task.Check every connection, in fact, it is almost impossible, and thus leads to the final PCB problems, such as the wrong attachment, suspension node, etc. PCB design

Schematic capture phase generally faced with the following questions:

The underline error： such as APLLVDD and APLL_VDD
Case problem: such as VDDE and vdde
Spelling mistakes
Signal is short circuit problem
and so on
In order to avoid these mistakes, should have a method can in a few seconds to check the whole schematic diagram.This method can be used to simulation, schematic diagram and schematic diagram of simulation in the current circuit board is rarely seen in the design process.By schematic simulation outputs can be viewed on the requirements of the node as a result, it can automatically check all connection problem. PCB design

In complex circuit board design, connection number may reach thousands, but very small amounts of change is likely to waste a lot of time to check.

chematic simulation can not only save design time, and can improve the quality of circuit board, and improve the efficiency of the entire process. PCB design

Equipment under test after some preset adjustment will have all kinds of signals, and there are a variety of modules, such as stabilizer, op-amp, used in signal adjustment.Consider a power signal is obtained by voltage stabilizer examples:

pcb design

In the process of test platform to create, to have incentives to signal to the necessary input, and then the output signal of interest point observation.

Can connect the probe to achieve the above process to be seen nodes.The principle diagram of the node voltage and waveform can indicate if there is any mistake.All signal connections will be automatically check.

with the help of simulation, we can directly observe the results, make sure the principle diagram of the circuit board is correct.In addition, by carefully adjusting excitation signal or component values can also implement a design change.Therefore schematic simulation can save the PCB design and inspection personnel of a lot of time, and increase the chance of the correctness of design.
