kareem 6d1d618974 reharden!: gpio_control_block
- rtl updated
~ add one column to the right to pass placement congestion
~ density adjusted (probably has no effect)
+ manually add isosubstrate layer in mag and gds from older iterations

!important still need to run dynamic simulations
!important depends on some updates to openlane
!important need to be able to recreate using newer openlane versions

kareem aaa3b863e5 reharden!: gpio_control_clock
- add met5 obs to avoid drc with the top level pdn

!important: still need to use the latest openlane to replicate

kareem 85f7f86c4e reharden!: gpio_control_block
- high level changes:
* add larger buffers on output ports
* add buffers on input ports
* adjust sdc file increasing output load and setting a high transition

- detailed changes:
* add interactive script for openlane where the order of events is a bit shuffled
	- to add obstruction before pdn
	- to manually insert buffers on some ports
	- to manually remove buffers inserted by synthesis on for example serial_clock_out
* change openlane config adding extra row and columns to increase the space and fit the
added buffers
* change config to enable buffering
* increase density for better placement?
* change the cell exclude list. some excluded cells didn't make sense
* ef decap cells break dynamic sims?
* add custom pdn script for to duplicate the old pdn

- misc changes:
* fix openlane makefile to properly detect interactive script

kareem c1e0d5ba06 openlane!: reharden gpio_control_block
update gpio_control_block config for new openlane versions:
- disable `SYNTH_BUFFERING` and `SYNTH_SIZING` to limit the design size
and fit the floorplan
- change `SYNTH_STRATEGY` to `AREA 0` to minimize design cells
- disable `PL_RESIZER_TIMING_OPTIMIZATIONS` and
enable `GLB_RESIZER_TIMING_OPTIMIZATIONS`
- remove `FP_IO_*` and replace them with `FP_DEF_TEMPLATE` for io placement
- set `DECAP_CELL` to not use ef decaps.. i think that was for simulations?
- enable some turned off `QUIT_*` variables
- replace deprecated variables such as `GLB_RT_*`
- customize `pdn.tcl` to force pdn straps to follow the old pattern
- replace `$script_dir` with `$::env(DESIGN_DIR)`

!IMPORTANT - still need to run dynamic simulations

Caravan top lvs (#67)
* - update caravan configuration
* change correct gpio_default blocks instance names
* implement powerrouting work around
* place spare logic blocks
* keep the history of runs and sym link last/final one

* - update caravan mag, def and gl views
- add fake power routing cell in the rtl as a placeholder for openlane
  to prevent routing on that cell
- fix some syntax errors in chip_io_alt
- match simple_por lef pins with mag by regenerating it

* Apply automatic changes to Manifest and README.rst

* add caravan power routing lef

* - update mag and def view of caravan
- add_macro_placement for fake cell

* Added back the power routing to Caravan, fixed DRC errors, ran LVS,
corrected placement of isolated substrate regions, and replaced the
signal routing for the analog lines.  Be aware that merging with
main may cause issues with the mgmt_protect.mag file and its
subcells mprj2_logic_high.mag and mprj_logic_high.mag.  It may be
worth cherry-picking the files to merge and exclude those layouts.
