Beschreibung
Zusammenfassung:	A transmission line width adjusting system for printed circuit boards comprises a layout acquisition module, a current loading module, a voltage drop measurement module, and a width calculation module. The layout acquisition module acquires the layout of a circuit board, and a transmission line is arranged on the layout. The current loading module loads an analog current to the transmission line. The voltage drop measurement module calculates the voltage drop on the transmission line according to the current loaded to the transmission line and the parameters of the transmission line. The width calculation module compares the voltage drop on the transmission line with an allowable maximum voltage drop, and calculates the appropriate width of the transmission line according to the voltage drop on the transmission line, the allowable maximum voltage drop and the width of the transmission line. The invention further discloses a transmission line width adjusting method for printed circuit boards.
