Revert the user_id_programming.mag file
 2023-11-04 18:18:52 -07:00
Tim Edwards b9a2e3ad7f Revert the user_id_programming.mag file back to the state it was 
in before my Sept. 25 commit, where it accidentally got
overwritten when magic decided it needed a timestamp update
for some reason, destroying my manual edits in the process.

Tim Edwards 15bd09f066 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".

Merge pull request #506 from efabless/main 
merge from main to cocotb
 2023-10-03 10:02:58 +03:00
Tim Edwards b3273ca5aa 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.
 2023-10-01 21:11:33 -04:00
Tim Edwards 495bf5fc5d 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.
 2023-09-27 15:07:58 -04:00
Tim Edwards 990f5dffc9 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
Tim Edwards 2251bad60f 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.

Tim Edwards 7bfab382d8 After updating from the PR that adds the gate level chip_io_openframe.v, 
modified it so that it matches the modified chip_io_openframe layout
in this PR (namely, the GPIO "_wrapped" pads are replaced with the
equivalent non-wrapped base cells).

Merge branch 'main' into fix_openframe_wrapper_interface 2023-09-25 19:41:30 -04:00
Tim Edwards 31c8f54f24 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.

Tim Edwards 9a48f4c998 Swapped the positions of gpio_dm0[38] and gpio_dm1[38], which 
were swapped in the openframe project wrapper layout, per
Mitch Bailey's observation in the #shuttle-development Slack
channel.
