Which software is better for signal simulation?

Do you know what signal simulation software there is? How to choose? "All voltage and current anomalies caused by active devices and passive components, including noise and interference in amplitude, jitter and dislocation in timing, etc."

Why learn signal simulation?

Signal simulation is a preliminary verification and an avoidance of the risk of design failure in later projects. Nowadays, the functions of integrated ICs are becoming more and more powerful. Digital, analog and radio frequency functions are integrated into one SoC. As a result, the number of discrete components on the PCB is gradually reduced, but it also affects the production process of the PCB and the layout of the PCB components. , wiring requirements are more stringent. The copper foil on the PCB is no longer just a flat copper cable that implements related network interconnections between devices, but has evolved into a microwave transmission line network.

What software should I use to learn signal simulation?

There are a variety of simulation software on the market, and countless circuit designers and verifiers use various circuit simulation software tools every day. So what kind of simulation software should a novice choose? Now we have compiled several commonly used signal simulation software for you.
