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.
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.
includes RTL change inside the padframe definition to remove one
previously unnoticed hard-wired connection between VDDIO and a
3.3V domain digital input pin.
