Designer 15 printed circuit board and electronic system level design software comes with novel Pin Pairs feature to enable accurate length and phase tuning across termination components; and enable length, phase and delay tuning traversing an entire signal path. Is said to eliminate need to have external software to maintain complex lists of signals and nets, but instead allows planning and routing groups of high-speed nets with greater efficiency and accuracy. Supports IPC-2581 and Gerber X2.
