VGA Clock

simple project to show the time on a 640x480 VGA display.

FPGA Build instructions

It's setup to run on an icebreaker with VGA pmod plugged into pmod1a.

type

make prog

to build & upload to the icebreaker

FPGA utilisation

using logLUTs to record resource usage and max frequency over commits:

ASIC utilisation

using the Skywater/Google 130nm process and OpenLane

• copy contents of rtl directory to designs/vga_clock/src/
• copy asic/config.tcl to designs/vga_clock/
• run ./flow.tcl vga_clock -init_design_config
• run ./flow.tcl -design vga_clock

This results in a routed design that uses 180x180 microns.
