and power routing cell

kareem 6452f14de0 reimplement caravel with latest blocks updates and a buffer macro 2022-10-13 13:34:47 -07:00
kareem 9ccb0ff2ed reharden!: caravel
~ reimplement based on updated views of the macros
~ change interactive script to call label_macro_pins
~ extract all spef and sdf corners using timing-scripts repo

!important same work arounds as before

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 aba145e0e2 Made modifications in support of changing the hard-coded default
configuration of GPIO 3 (CSB) from a standard input to a weak
pull-up input.
