Gregory's ServerThe 386 was originally scheduled for 50 person-years of development time, but it fell behind schedule. The designers made a risky decision to use "automatic place and route", letting software do some layout. This worked and the chip was completed ahead of schedule. 2/17

@kenshirriff is this thread something that will be continuing at a later date? Or maybe a federation issue - I’m only seeing up to 3/17  @hugh The whole thread is there but sometimes people have trouble seeing all of my threads. @kenshirriff weird. Will see if I can get at it if I’m not logged in, or maybe just on the web. Thanks |
Early chips had every transistor drawn by hand. Federico Faggin, designer of the popular Z80 processor (1976), spent three weeks drawing transistors but the last few transistors wouldn't fit so he had to erase everything and start over. The result was dense and chaotic. 3/17
