Tim Edwards b0d3217280 Replaced the gpio_defaults_block_0000.mag layout with gpio_defaults_block.mag
so that it contains a valid layout after processing by Openlane (since the
verilog module is named gpio_defaults_block).  Corrected the orientation of
the defaults block layouts on the right side of Caravel and erased the
incorrect routing there.  Reinstated the copyright, user ID text, open source
logo, and Caravel logo.  Revised the gen_gpio_defaults.py script to handle
the first five GPIOs in the same way as the others, although as fixed entries
which cannot be modified by the user project designer.

Tim Edwards f18a219be4 Modified the set_user_id script so that if it happens to be run on
a repository where the user_id_programming GDS has been compressed,
it will handle it correctly.

Tim Edwards 4a27ea4c6b Finished first draft of the gen_gpio_defaults.py script, which now
makes backup copies of caravel and caravan layouts and replaces the
cell name of any gpio defaults block that is changed from the
contents of user_defines.v.  NOTE:  user_defines.v ultimately must
reside in the user project.  The Makefile should copy the user's
version into the caravel directory space before running the script,
or else the script should be rewritten to reference the user's
project area when reading user_defines.v.

Tim Edwards 6a93ea582d Added a script which parses the file "user_defines.v" in
verilog/rtl/, and creates all the layout files needed to represent
all unique combinations of defaults used in the file.  Not done:
Modifying the top level layout to use the correct defaults (because
the top level layout does not yet exist).

Tim Edwards a67cbcb01c Added back a couple more files related to the user ID programming block. 2021-10-26 10:40:55 -04:00
