~ increase width for more spread decaps
+ add or cells to cell exclude
~ change placement density in accordance to area
~ change padding to allow for space for decaps
~ increase height for more spread decap insertion
+ add or cells to cell exclude
~ adjust pdn to have an offset half to pitch
~ change placement density in accordance to area
~ change padding to allow for space for decap insertion
~ enable synth buffering to fix fanout
~ add *buf_1* to no synth list
~ add attribute (* keep *) to the oscillator as dont
touch for yosys
!need to verify that the oscillator remains untouched
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).
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.
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.
based on feedback from tim in order to generate a lef view
with a zero origin and avoid any hacks
+ add caravel_power_routing lef
+ sync caravel_power_routing gds and mag
