* added views for each step of generating final caravel.gds
* generated the right caravel and caravel-eco gds
* renamed caravel_signoff and removed caravel-non-eco

* reharden: caravel
~ shift caravel_clocking due to change in size
~ change the pr boundary of caravel_power_routing mag file
~ regenarate lef of caravel_power_routing
* update pdn for `caravel_clocking` & `digital_pll`
* added script to update and generate the power routing views
* ~ run update_power_routing_views from the caravel root with prboundary
* fix output message
* added power routing lef, mag and gds
* fix update_power_routing_views saving wrong cell name
* reharden: caravel
~ incorperate pdn changes
~ re-extract spefs
* fix caravel_power_routing views
* fix abs path in maglef views
* fix abs path in mag views
add substcut layers in gpio_control_block and mgmt_protect

~ 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
the RTL, but cleaned up for macro definitions; this can be used
for LVS. The decap cells were hand-edited in because there is
no way to devine them from the RTL source.
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).
