Effectively reverted the change to add spare logic blocks near each (#157)
* Effectively reverted the change to add spare logic blocks near each
of the GPIO control blocks by changing the definition of
NUM_SPARE_BLOCKS to 4 (the original number of spare logic blocks)
for both caravel and caravan top level RTL verilog modules.

* Apply automatic changes to Manifest and README.rst

Tim Edwards f5a9d4677e Revert "Implemented fix from early issue #16. Finally decided to pull the"
This reverts commit 577cc12fe0.

Reverting the change from issue #16.  After some discussion, it has
been decided that it is up to the user to implement the pull-up and
pull-down modes correctly by setting the output enable and driving
the output to the appropriate value.  Note that this should be well
documented, if by nothing else than a validation testbench that
excercises a user pull-up and pull-down input mode.

Modified the set_user_id.py script so that mode "-report" returns a valid value. (#93)
* Modified the set_user_id.py script so that mode "-report" returns
a valid value, instead of throwing an error, because the "info.yaml"
file was removed without due consideration of the side effects.

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.

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.
