# Makefile for efabless design kits for SkyWater Sky130:
#
#  sky130A      =  5-metal backend stack with dual MiM
#
# Written by Tim Edwards March 2019
# efabless corporation
# updated October 2019
# updated December 2019 (divide installation sections for individual tools)
# updated March 2020 (refactored the install process)
# updated May 2020 (changed to new process name Sky130)
#
# Instructions:
#
# Modify values below as needed:
#
#	VENDOR_PATH: points to vendor sources
#	EF_STYLE: 1 for efabless style, 0 otherwise
#	LINK_TARGETS: link back to source or link to 1st PDK when possible
#	DIST_PATH: install location for distributed install
#	LOCAL_PATH: install location for local install or runtime location
#		    for distributed install
#
# Run "make" to stage the PDK for tool setup and vendor libraries

# If installing into the final destination (local install):
#
#   Run "make install-local" to install all staged files
#   ("make install" is equivalent to "make install-local")
#
# If installing into a repository to be distributed to the final destination:
#
#   Run "make install-dist" to install all staged files
#
# Run "make clean" to remove all staging files.
#
# Run "make veryclean" to remove all staging and install log files.
#
# For the sake of simplicity, the "standard" local install can be done
# with the usual
#
#   make
#   make install
#   make clean
#

# If EF_STYLE is set to 1, then efabless naming conventions are
# used, otherwise the generic naming conventions are used.
# Mainly, the hierarchy of library names and file types is reversed
# (e.g., sky130_fd_sc_hd/lef vs. lef/sky130_fd_sc_hd).

# If LINK_TARGETS is set to "none", then files are copied

# PDK (e.g, "sky130A"), then symbolic links are made to the
# same files in that PDK, where they exist, and are copied
# from source, where they don't.
