Incorrect descriptions for sky_fd_pr_rf libraries #2

Closed mithro closed 4 years ago

mithro commented 4 years ago

https://github.com/RTimothyEdwards/open_pdks/blob/7ec769750bff68becb2305893821a7bbd8df8118/sky130/README#L175-L176

The following descriptions are wrong;

 sky130_fd_pr_rf/       RF primitive devices w/fixed layout 
 sky130_fd_pr_rf2/      Additional RF primitive devices w/fixed layout

It should be something like the following;

 sky130_fd_pr_rf/       Older library of RF primitive devices w/fixed layout for compatibility (don't use in new designs).
 sky130_fd_pr_rf2/      Current library of RF primitive devices w/fixed layout (use in new designs).

@mithro : Last I saw from the interim skywater-random repository, pr_rf contained all the primitive devices for transistors, and pr_rf2 contained a few cells possibly overlapping with pr_rf plus a lot of cells of unknown origin and unknown usability. For example, if you consider pr_rf to be somehow deprecated, then you will not have any bipolar transistors in the process.

This should have all been resolved since the sky130_fd_pr repository was released, so I'm closing this now.
