  4. High speed digital systems laboratory המעבדה למערכות ספרתיות מהירות Specification • Hardware • Pulser - creates short (0.5-1 nsec) and long (10-13 nsec) pulse signal with very low rise/fall time (200ps) . • Signal Splitter – launching a signal into a transmission line and converts differential signal to single ended while only one line can be alive at the same time • Analog Switches – transmit the measured voltage signal on input/output of selected transmission line to oscilloscope. • Transmission Lines – will contain 36 microstrip, single ended transmission lines with different terminations. • Controller – Based on Altera DE2 Board, controls all of the operation of the High Speed Transmission Line Board. • PCB Design • 8 layers, 25x30cm board dimensions. • High speed data lines, microstrip and stripline formats. • Rise time of signals range from 150ps to 300ps. • Pre and post layout simulations are required. • Multiple onboard power supplies – many local power planes. • Many identical hierarchical blocks on a schematics require efficient layout reuse. • Design is completed in OrCAD PCB Editor 4
