experimentation with gnu make for Xilinx Vivado compilation. dependencies can be complicated.

Introduction

This project demonstrates the use of gnu make to build FPGA designs using Vivado.

files

The build scripts are:

    ./build2/Makefile    - the makefile that compiles the whole design
    ./build2/xci2dcp.tcl - compiles .xci logic core files into .dcp design checkpoint files.
    ./build2/bd2dcp.tcl  - compiles an IPI block diagram description into a .dcp file.
    ./build2/hdl2dcp.tcl - uses out_of_context synthesis to convert sub-designs into .dcp files.
    ./build2/synth_top.tcl - converts the top level design into a synthesized .dcp file.
    ./build2/dcp2bit.tcl - does place, route and bitstream generation on the top level design.
    ./build2/bit2mcs.tcl - creates the .mcs programming file from the bit file.

dependency hierarchy

The build hierarchy of the example design is shown below.

top.mcs
    top.bit
        top.v
        top.xdc
	    system.dcp
	        system.tcl (an IPI block diagram)
        sig_gen.dcp
            sig_gen.v
            sig_gen.xdc
            ddc_compiler_0.dcp
                ddc_compiler_0.xci
            c_counter_binary_0.dcp
                c_counter_binary_0.xci
        clk_wiz_0.dcp
            clk_wiz_0.xci

compile instructions

1. Install the Xilinx Vivado tools.
2. Add Vivado to path with something like this source /opt/Xilinx/Vivado/2017.2/settings64.sh
3. Change to the build folder.
4. run "make --jobs=4". You can test the dependencies by using the "touch" linux command on any of the source files.

Enjoy!
