Description Luke Kenneth Casson Leighton 2022-07-12 13:18:15 BST 
coriolis2 layout of eth_mac is needed, and a preliminary investigation into
features in coriolis2 needed to support it.

for full report on evaluation of SRAM, see bug #934.
Comment 1 Luke Kenneth Casson Leighton 2022-07-12 13:21:28 BST 
to keep this layout simple the SRAM should not be included. as it is not
going to fab the size of the GDSII is not relevant.

    Correct spacing between the devices so they do not overlap (cosmetic).

    Added a SPRAM only design to experiment on matrix placement rebuild.

    * See comments in sramplacer2.py plugin in Coriolis for the results.
