* New: In cumulus/plugins.chip.pads, add METAL5 jumpers on all wires
    going to/from the I/O pads on the East & West side. This is a
    quick hack as:
      1. We should put it also on North/South, but no violation
         happens here.
      2. We should put it on *ouput* wire only (for only those are
         connected to transistors gates).
* New: In cumulus/plugins.chip.macro, put jumpers on the East side
    connectors for the SRAM block. Also a quick hack, not robust for
    anything else than the SRAM.
