            Bug ID: 934
           Summary: Evaluation of optimized placement for Yosys generated
                    SRAM
           Product: Libre-SOC's second ASIC
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: CONFIRMED
          Severity: enhancement
          Priority: ---
         Component: Milestones
          Assignee: lkcl at lkcl.net

   NLnet milestone: ---

A SRAM has intrinsically a matrix-like structure. Letting it placed by the
regular placer results in a medium loss of area, but more importantly, much 
longer wiring. This increase of wiring is likely to make the overall design
much more difficult to route. Not even mentioning timing issues.
