kareem f4218ddde9 reharden!: gpio_control_block
- reimplement using a sparecell
- reimplement using newest open_pdks

!important using openlane pre odb with some local patches which
most if not all are merged in the current head of openlane however
still takes effort to update the interactive script to be latest
openlane compatible

!important override abstract lef generated by openlane. openlane
 generates lef and mag that contain def BLOCKAGE layers that cause
congestions during top level routing

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 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

issue-105: caravel & caravan.mag: relabel top-level v*_core power nets (label PLUS underlying met5); (#110)
tweak blackbox lvs scripts for very fast extract; update spi/lvs/*.spice.
The .spice (once propagated to caravel-lite AND caravel-lite embed in mpw_precheck docker)
will pass the consistency check.

R. Timothy Edwards 71600440bc
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.
