Ref-<You already said that AMD did not copy the Intel 486 chip design and layout. But unless the hardware is absolutely identical, the Intel microcode would not work on the AMD design>

The chip layout and circuit design were different, but the logic design was the same. If the logic design was a little different, the microcode would have to be significantly different. Apparently AMD was not comfortable with significant changes to the microcode, and elected to minimize the design risk by substantially copying Intel.

Regarding the IDIV I am not familiar with with the details.The court ruled that AMD copied the Intel microcode.
