--- Comment #16 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
Staf: we still need that cell library (aka liberty file) with just the one
item in it: SPBlock_512W64B8W

as none of us in libresoc know how to create liberty files the project is held
up until this is available.

question: if we were to take the IO pad library, which if i remember correctly
you said only has one cell in it, and replace its files with the model in
comment #8 would that work?

as we do not know how liberty files are made we need a *simple* template to
start from and the IO pad library would be as good a starting point as any.

if that is the case, is there anything that we need to know to make that cell
library containing one item?

once we have one example like this it should be possible to create the PLL and
the SRAM-DFF version, but until we have the one example everything is held up.
