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 285ef6b642 reharden!: caravel 
~ update the following views:
def
mag
verilog
spef(all corners)
+ add the ability to override the interactive script filename
+ add the ability to run openlane regression using regression.config
file
~ change GRT ADJUSTMENT values
~ change pointers to some files for workarounds

!important the interactive script still needs updates
!important this was done using old openlane v0.22 and its matching
pdk
!important known workarounds:
- a custom techlef is used where large metal spacing rules are the
only ones present to avoid violations by the router
- some odd behaviour happening when a macro has a lef view
with a non zero origin. so the power routing cell is (temporarily)
modified to have a zero origin and its placement has been shifted
which doesn't match the power routing mag.
- the old openlane doesn't generate multi spef corners. they
are generated using timing-scripts repo

Tim Edwards 2459b3583e Updated all views of chip_io and chip_io_alt based on the abstract 
view of constant_block which was recently merged into the repository.
The constant_block instance positions and connections were modified
slightly to avoid routing over obstruction areas.

Tim Edwards eceb71ee04 Added GDS, DEF, and LEF views of both chip_io and chip_io_alt. 2022-10-08 22:24:38 -04:00
Tim Edwards bd4f053ec1 Updated I/O layouts with constant_block instances from M. Hosni's 
fork of caravel (layout .mag file not copied into this commit).
The layouts of both chip_io and chip_io_alt are believed to be
complete, but need verification (with LVS).

Tim Edwards fd29bb3442 Generated new chip_io_alt layout to match the chip_io changes in 
the previous commit.  Fixed a few minor errors in the chip_io
layout.  Waiting on layout of constant_block to finish.
