~ 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
~ 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
* REVERT ME: temporarily match simple_por pin in verilog with lef
* - update configs
- add patch file for power routing def
* - update the following caravel toplevel views
- gl
- mag
- def
- add caravel power routing def
* Apply automatic changes to Manifest and README.rst
* update gl mag and def for caravel
* Revert "REVERT ME: temporarily match simple_por pin in verilog with lef"
This reverts commit b70c27c69f.
* update caravel gds
* Apply automatic changes to Manifest and README.rst
* Added text and logo cells back into the caravel top level. Put an
isolated ground marker layer on the xres_buf layout. Corrected
the power supply pin names on the gate level verilog netlist of
simple_por in caravel.v. Updated the copyright block text.
Corrected DRC errors in the top level routing.
