Reverted "chip_io_gpio_connects.mag".
...
Backed out an error in which the layout "chip_io_gpio_connects.mag",
which was used on caravel and caravan, was modified for openframe,
making it incompatible with caravel and caravan. Renamed it to
"chip_io_gpio_connects_vert.mag" which makes it unique to openframe
and also matches the nomenclature of "chip_io_gpio_connects_horiz".

Added the set of missing pins on the 2nd of the two vccd1/vssd1 power
...
pads to the user project wrapper layout, which were missing, as pointed
out by Marwan. Regenerated the wrapper DEF file from the updated
layout.

Stretched all metal3 pins 0.02um toward the center of the chip, so that
...
the length of pin inside the wrapper boundary is 0.3um, which is the
minimum metal3 layer width, and is required by the routing tool.

Found one additional minor adjustment was needed to the resetb_h
...
pin, which was neither 0.28um wide nor completely covered by
metal2.
2023-09-26 17:58:05 -04:00

Additional tidying up. All pins on the openframe wrapper are now
...
consistent (all metal2 pins the same width and length and all
metal3 pins the same width and length). The PR boundary was
moved back to where it was, 0.28um from the pin ends; that
causes overlap with the padframe but should not be an issue since
the openframe wrapper is manually placed. All pins reach from
0.28um inside the boundary to the bottom of the comment layer
(which is 2um wide). Some remaining pins which were not on a
10nm grid were corrected.

Modified the openframe padframe so that the GPIO "wrapped"
...
cells are replaced with the base cells. Routing to pins
is instead done in the "gpio_connects" cells while
improving on the original routing (fewer cross-overs,
multiple vias per contact, wider buses for the analog
signals). Made small adjustments to many of the openframe
wrapper pins to keep them all on a 10nm grid. Moved the
connections previously from the "wrapped" GPIO cell back
from the openframe project border, so that the border can
be clear of all blockages. Added the DEF file of the
wrapper (previously only in the openframe example repo)
to the def/ directory. Note: The modified LVS scripts
depend on the gate-level netlists of the frame, which
have been committed in a prior pull request. This pull
request does not conflict with those files.

Fixed the index of the port for "vssa1" in the caravel_openframe
