A powerful signal integrity analysis tool must be flexibility, easy to use and integrated into an existing EDA framework and design flow. In addition, it is important for the tool to be accurate enough. This report reviews a validation study for the Mentor Graphics HyperLynx 8.0 PI tool to establish confidence in using it for power integrity analysis.

For advanced signaling over high-loss channels, designs today are using equalization and several new measurement methods to evaluate the performance of the link. Both simulation and measurement tools support equalization and the new measurement methods, but correlation of results throughout the design flow is unclear. In this paper a high performance equalizing serial data link is measured and the performance is compared to that predicted by simulation. Then, the differences between simulation and measurements are discussed as well as methods to correlate the two.

en 1994 se llevó a cabo la primera compra en línea de la historia: una pizza de pepperoni con champiñones y extra de queso en Pizza Hut. un año más tarde, amazon vendió su primer libro, Fluid Concepts & Creative Analogies: Computer Models of the Fundamental Mechanisms of Thought, de douglas Hofstadter2. dos décadas después, se calcula que las ventas mundiales de los comercios electró-nicos ascienden a más de 1,2 billones de dólares. ¿Qué ha hecho posible un cambio tan espectacular en nuestros hábitos de compra? la confianza.

Désormais, acheter sur Internet est devenu une seconde nature pour la plupart d’entre nous. Mais à quel moment ce phénomène a-t-il débuté, et sous quelle im-pulsion a-t-il atteint le niveau que nous connaissons aujourd’hui ? Selon plusieurs sources1, il faut remonter à 1994, date du premier achat sur Internet d’une pizza aux peppéroni et champignons avec supplément fromage chez Pizza Hut. Lorsque cette pizza a été commandée et qu’un an plus tard, Amazon vendait son premier livre (« Concepts & Fluid Analogies Creative : Computer Models of the Fundamental Mechanisms of Thought » de Douglas Hofstadter2), nous assistions sans le savoir aux prémices d’une déferlante qui a submergé le réseau. Presque vingt ans plus tard, en 2013, les ventes mondiales sur Internet dépassaient 1,2 trillion de dollars3. Au centre de cette révolution dans nos habitudes de consommation : la confiance

Gli acquisti online fanno ormai parte della nostra quotidianità, ma come è cominciato tutto questo e cosa ha fatto sì che sia cresciuto fino ai livelli odierni? Secondo le cronache1 iniziò tutto nel 1994, quando venne effettuato il primo acquisto sul Web: una pizza con funghi, peperoni e aggiunta di formaggio nella catena Pizza Hut. Con quella prima pizza e con la vendita, un anno dopo, del primo libro da parte del gigante del commercio online Amazon (‘Fluid Concepts & Creative Analogies: Computer Models of the Fundamental Mechanisms of Thought’, di Douglas Hofstadter2), ebbe inizio un’attività inarrestabile. Vent’anni dopo, nel 2013, le vendite mondiali di e-commerce sono state stimate in oltre 1.200 miliardi di dollari3. Cosa ha reso possibile questo cambiamento epocale delle nostre abitudini di acquisto? La fiducia.La fiducia nei siti presso i quali acquistiamo, nonché la fiducia che le informazioni di acquisto da noi fornite siano al sicuro. Perché, come sempre, dove ci sono soldi
