1. Technical Field
Embodiments of the present disclosure relates to circuit simulating systems and methods, and more particularly, to a computing device and a method for checking signal transmission lines of a circuit board.
2. Description of Related Art
A circuit board may be arranged with thousands of signal transmission lines. To ensure integrity of signals transmitted by the signal transmission lines, designs of the signal transmission lines should satisfy design standards. For example, a length of each line segment of a signal transmission line should satisfy a predetermined standard, so that each line segment of the signal transmission line has an appropriate impedance to ensure signal integrity. Spaces between neighboring signal transmission lines should also satisfy predetermined standards, to reduce crosstalk of the neighboring signal transmission lines. Therefore, it is necessary to incorporate design simulations and checks during the design and layout process of the circuit board. However, presently, obtaining information from a circuit board layout are often acquired manually. With the large quantity of signal transmission lines distributed on the circuit board, manual operation is not only time-consuming, but also error-prone.
