Merge pull request #260 from efabless/fix_top_buffers_again 
More changes to the GPIO buffer cell
 2022-10-17 03:35:25 +02:00
Tim Edwards 9f54b2ecec Added a gate-level version of gpio_signal_buffering derived from 
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.

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
