Re: "I am confused:) How hardware VALIDATION can include SIMULATION data? So, is this still a "theory", or real hardware? Looks like again a sort of vaporware... I guess Elmer has good overtime pay these days :)" Ali, your confusion doesn't matter to the big picture. You don't need to understand for it to happen. Just keep your eyes open for a little while longer and you will see... EP

Hi Ali Chen; My interpretation of that HardOCP info is at #reply-11568974 Essentially, launch voltage refers to the voltage of the data bus (at the pin of the driving RDRAM), at the moment the chip starts to drive a low voltage (logic one). Because of the way the bus is terminated, each output has to drive through its own reflections. It's kind of a nasty spec, you can explore the links to the above post if interested. My expectation is that this technology isn't going to be very rugged in the field. I would guess predict that the box maker's test engineers are really pounding hard on these chips. I know nothing about the AGP4X specification. Could you provide a link or a little more illumination on that 100ps specification they've got? Seems pretty tight. Timing that critical is usually hard to meet, but there are a few exceptions. (For example, two equivalent outputs from the same chip with the same waveform, and driving identical loads, and located close to each other...) -- Carl
