# gen_gpio_defaults.py ---
#
# Manipulate the magic database and GDS to create and apply defaults
# to the GPIO control blocks based on the user's specification in the
# user_defines.v file.
#
# The GPIO defaults block contains 13 bits that set the state of the
# GPIO on power-up. GPIOs 0 to 4 in the user project area are fixed
# and cannot be modified (to maintain access to the housekeeping SPI
# on startup). GPIOs 5 to 37 are by default set to be an input pad
# controlled by the user project. The file "user_defines.v" contains
# the state specified by the user for each GPIO pad, and is what is
# used in verilog simulation.
#
# This script parses the user_defines.v file to determine the state
# of each GPIO. Then it creates as many new layouts as needed to
# represent all unique states, modifies the caravel.mag layout
# to replace the default layouts with the new ones as needed, and
# generates GDS files for each of the layouts.
#
# gpio_defaults_block layout map:
# Positions marked (in microns) for value = 0. For value = 1, move
# the via 0.69um to the left. The given position is the lower left
# corner position of the via. The via itself is 0.17um x 0.17um.
# The values below are for the file gpio_defaults_block_1403.
# Positions marked "Y" for "Programmed One?" are already moved to
# the left, and so should be move 0.69um to the right if the bit
# should be zero.
