How did they test and debug this stuff in the 70s
- phire 2y agoFor the 8086 they had a gate level simulator called LOCIS. The problem is that intel historically designed everything at the transistor level, so the 8086 didn't map onto a gate level simulation very well. The "Coping with the Complexity of Microprocessor Design at Intel – A CAD History" paper [1] goes into details of what they used in the 80s and onwards, but it does briefly mention what they were doing before that.
