- I’ve been studying the standard cell circuitry in the Intel 386 processor recently. The 386, introduced in 1985, was Intel’s most complex processor at the time, containing 285,000 transistors. Intel’s existing design techniques couldn’t handle this complexity and the chip began to fall behind schedule. To meet the schedule, the 386 team started using a technique called standard cell logic. Instead of laying out each transistor manually, the layout process was performed by a computer.
