# foundry_install.py
#
# This file generates the local directory structure and populates the
# directories with foundry vendor data.
#
# Options:
# -link_from <type> Make symbolic links to vendor files from target
# Types are: "none", "source", or a PDK name.
# Default "none" (copy all files from source)
# -ef_names Use efabless naming (libs.ref/techLEF),
# otherwise use generic naming (libs.tech/lef)
#
# -source <path> Path to source data top level directory
# -target <path> Path to target top level directory
#
#
# All other options represent paths to vendor files. They may all be
# wildcarded with "*" to represent, e.g., version number directories,
# or names of supported libraries. Where wildcards exist, if there is
# more than one directory in the path, the value represented by "*"
# will first be checked against library names. If no library name is
# found, then the wildcard value will be assumed to be numeric and
# separated by either "." or "_" to represent major/minor/sub/...
# revision numbers (alphanumeric).
#
# Note only one of "-spice" or "-cdl" need be specified. Since the
# open source tools use ngspice, CDL files are converted to ngspice
# syntax when needed.
#
# -techlef <path> Path to technology LEF file
# -doc <path> Path to technology documentation
# -lef <path> Path to LEF file
# -lefanno <path> Path to LEF file (for annotation only)
# -spice <path> Path to SPICE netlists
# -cdl <path> Path to CDL netlists
# -models <path> Path to SPICE (primitive device) models
# -liberty <path> Path to Liberty timing files
# -gds <path> Path to GDS data
# -verilog <path> Path to verilog models
#
# -library <type> <name> [<target>] See below
#
# For the "-library" option, any number of libraries may be supported, and
# one "-library" option should be provided for each supported library.
# <type> is one of: "digital", "primitive", or "general". Analog and I/O
# libraries fall under the category "general", as they are all treated the
# same way. <name> is the vendor name of the library. [<target>] is the
# (optional) local name of the library. If omitted, then the vendor name
# is used for the target (there is no particular reason to specify a
# different local name for a library).
#
# All options "-lef", "-spice", etc., can take the additional arguments
# up <number>
#
# to indicate that the source hierarchy should be copied from <number>
# levels above the files. For example, if liberty files are kept in
# multiple directories according to voltage level, then
#
# -liberty x/y/z/PVT_*/*.lib
#
# would install all .lib files directly into libs.ref/lef/<libname>/*.lib
# while
#
# -liberty x/y/z/PVT_*/*.lib up 1
#
# would install all .lib files into libs.ref/lef/PVT_*/<libname>/*.lib
#
# Other library-specific arguments are:
#
# nospec : Remove timing specification before installing
# (used with verilog files; needs to be extended to
# liberty files)
# compile : Create a single library from all components. Used
# when a foundry library has inconveniently split
# an IP library (LEF, CDL, verilog, etc.) into
# individual files.
#
# NOTE: This script can be called once for all libraries if all file
# types (gds, cdl, lef, etc.) happen to all work with the same wildcards.
# However, it is more likely that it will be called several times for the
# same PDK, once to install I/O cells, once to install digital, and so
# forth, as made possible by the wild-carding.
