Meathead, ASIC design is viewed as purely digital by many designers. One does not need even a college engineering degree to do ASIC design. I have known several ASIC designers who were truly ignorant of electrical design and had no degree in engineering. They did however have a capacity for working 60 and 80 hour weeks. SUN had a small separate engineering group that used TLC, Greenfield, SPICE, etc to establish engineering design rules for PCB design of its workstation and server products. These were by and large MSEEs from Stanford. Their boards had a traces through them to measure the batch to batch variations in the boards. They had very few problems with their PCBs. I believe that INTEL designs their own PCBs in order to avoid taking the hit for other manufacturer's poor quality mother board designs. I believe this is one of the reasons they went to the slot 1 cartridge. Early on the Taiwanese manufacturers did not have electrical and board level simulation capability and this resulted in yield problems during high volume manufacturing. Companies like CHPS had a board design group which designed boards around their latest chips and then gave the design packages awy to manufacturers so they could quickly create an OEM market for their chips. CHPS design methodology did not include any electrical or board level simulation. This caused them big time trouble as the clock speeds went up on chips. Just a little history.... Jim Kelley
