D. Mitch Bailey 092ff66da0 Correct user_id bit order in gl verilog and layout. 2023-12-05 16:05:25 -08:00
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 e6169aaf8c Copied files from the original pull request into a new one. Includes 
a few layout updates since the original pull request.  The openframe
design matches the user example in caravel_openframe_project.

Passant d5e24e49b8 - remove old spef mapping script 2023-04-26 09:19:51 -07:00
Tim Edwards 5c59ae6eba Updated the verify_defaults_blocks.py script to also check the 
modified caravel_core.mag layout to ensure that all the defaults
blocks got the correct substitutions.  Previously, only the
individual defaults blocks layouts were checked and verified.

Tim Edwards cca54a2a74 Final LVS run reports for caravel and caravan top levels, showing LVS 
clean.  Provides the netgen report, JSON file, and run-time log of
each.  Modified the scripts to tee into the run-time log file and to
add the SPICE netlist of the simple_por.  Corrected the simple_por
netlist to make the xhigh resistors non-width-specific, since the
width-specific ID mask is not a GDS layer and cannot be reconstructed
from GDS (at least not with the current tech file in magic).

Tim Edwards 94461a3125 Added LVS results for caravel and scripts for running caravel and 
caravan LVS using the new PDK to update the chip GDS.  Moved files
to their proper places.  Still waiting on caravan LVS result file.
