update pdk magic version to v294 2022-04-25 11:31:16 -07:00
R. Timothy Edwards b2089fe9eb
Corrected the gpio_control_block so that the user_gpio_out signal (#89)
does not pass through an inverter, so that the input can remain
unconnected.  Rewired the existing implementation to use an
alternative gate that has an inverting input so that the
user_gpio_out signal can be left undriven when the GPIOs are in
the management enable state.  This is a simple logic refactoring
and does not change the logic function.  The manual rewiring has
been confirmed by LVS, but at least one GL simulation should be
run to confirm that the logic function remains the same as before.

Corrects four signal routes which were missing from the caravan top level (#88)
* Corrects four signals which were missing from the caravan top level
(management output and output enable to GPIO 0 and 1---these errors
would have prevented the houskeeping SPI from working on caravel).
Corrected RTL verilog (source of the error), GL verilog, and layout.

* Apply automatic changes to Manifest and README.rst

Fixes an error in the gen_gpio_defaults.py script (#79)
* Fixes an error in the gen_gpio_defaults.py script that is incompatible
with the use of indexed arrays for five of the gpio_defaults_block
instances.  Previously this was handled by manually changing the names
in the layout file.  This script avoids the need for manual modification
by directly handling the indexed notation.  Also, this extends the
modifications made to the layout to include the first five defaults
blocks;  otherwise, the first five defaults blocks are not changed and
the defaults will be wrong for the housekeeping SPI pins.

R. Timothy Edwards 99518acd15
Numerous bug fixes, ending in clean full LVS for both caravel and caravan. (#76)
* (1) Modified the .magicrc file to set a default for PDK if not set in the
environment.  (2) Fixed the user ID programming layout to not leave holes
behind when the script moves the vias around (similar to the handling of
the GPIO defaults block).  (3) Added substrate isolation to gpio_control_block
and fixed the path references to the standard cells.  (4) Fixed the four
missing routes on the Caravan top level.  (5) Reinstated the large rendered
labels for the pads on both caravel and caravan.  (6) Corrected the top
level gate-level netlist for caravan to add the missing pins to the
management core wrapper.  (7) Did the same for the caravan top level RTL.
(8) Created scripts to run full LVS including extracting the management
core wrapper and reading all gate-level verilog submodules.  (9) Moved all
of the LVS scripts to the scripts directory.

* Made the changes from pull request #73 as they did not get merged
successfully, and if merged now they will generate conflicts with
this pull request in scripts/set_user_id.py.  So it's easier to
just manually add them to this pull request.

Caravan top lvs (#67)
* - update caravan configuration
* change correct gpio_default blocks instance names
* implement powerrouting work around
* place spare logic blocks
* keep the history of runs and sym link last/final one

* - update caravan mag, def and gl views
- add fake power routing cell in the rtl as a placeholder for openlane
  to prevent routing on that cell
- fix some syntax errors in chip_io_alt
- match simple_por lef pins with mag by regenerating it

* Apply automatic changes to Manifest and README.rst

* add caravan power routing lef

* - update mag and def view of caravan
- add_macro_placement for fake cell

* Added back the power routing to Caravan, fixed DRC errors, ran LVS,
corrected placement of isolated substrate regions, and replaced the
signal routing for the analog lines.  Be aware that merging with
main may cause issues with the mgmt_protect.mag file and its
subcells mprj2_logic_high.mag and mprj_logic_high.mag.  It may be
worth cherry-picking the files to merge and exclude those layouts.

Tim Edwards 680353f7a7 This corrects a shorted net in the caravel top level layout.
Still evaluating why the layout does not pass LVS like it did
previously, although all current LVS errors appear to be related
to magic's extraction of the isolated substrates, and do not
imply functional issues.  Also, LVS has only been done on the
top level.

Tim Edwards 53abff5bbf This commit fixes the issue with the user ID programming block not
getting changed by "make ship" because the build is done in a place
where the path pointer to the user_id_programming GDS still points
back to the original caravel repository, not the user project
repository.  The user_id_programming GDS was removed (no longer used),
the user_id_programming.mag file was modified to remove the path
pointer to the GDS, and the set_user_id.py script was modified to
make changes directly to the user_id_programming.mag file instead of
the GDS.  An additional method was added to the set_user_id.py script
to modify the gate-level verilog/gl/user_id_programming.v to make
the user ID correct for gate-level testbench simulations.
