Tim Edwards 69d353f65c Corrected the verilog and the layout for the caravan version of the 
signal buffering (verilog was missing one of the buffers, and the
layout had some of the labels at the top accidentally erased).

Tim Edwards f7e2dc80a6 Made a minor correction to the layout to remove an extra unused 
buffer.  This does not affect ongoing top-level routing work, but
is needed for LVS.

Tim Edwards 41775aedfd Changed the LEF views to restrict the pins to the route endpoints 
using the (accidentally undocumented) "-pinonly" option.

Tim Edwards 48ae31205c Another change to the pin endpoint positions to make sure that they 
have at least 0.28um spacing to the next wire.  Not sure that this
is going to solve the router errors, though.

Tim Edwards c5e7c67d60 Once again. . . Rewrote the RTL verilog so that only signals 
being buffered pass through the buffer macros.  Removed the
straight-through signals from the layout, and renumbered the
vectors in the buffer cells, which no longer match the numbering
at the top level (unfortunately).

Tim Edwards 589f351dcb Additional modification to move pins up into an uncongested area 
above housekeeping, because the upper GPIO pins are in the wrong
place relative to the new GPIO signal routing below the SoC.
Added pins for the pass-through connections.  Unconnected/
unrouted OEB pins are still not present and probably should be
removed from the RTL.

Tim Edwards dcc3c56b83 Some additional corrections to the gpio_signal_buffering cells. 
Corrected one instance where a buffer had incorrectly been replaced
with a decap cell.  Moved the left-hand side in by 0.6um to clear
the chip_io connections on the left-hand side.  Corrected a small
DRC error in a route position at the bottom.

like avoid obstructions in the padframe and power routing, add
