Great work thus far! Notes:

• Make sure all discussions of RTL hierarchy are consistent with specs. Notably, describing the module they must make as having a clock port is kind of deceptive because the HSOSC module provides the clock at the top level.
• Spoiler the example testbench and make sure the module name is lab1_led_controller_tb (and the module is lab1_led_controller). Arguably testbench design could be moved into a tutorial, though it would require new writing (main points: test benches must cover all functionality of module, combinational benches exercise every input combination, sequential testbenches nominally need to exercise every state transition but that can be a lot for counters, top testbenches only test stuff not covered by module tests)
• In pin assignment - modify the appropriate sentence to read "not being used for other purposes by checking the schematic" and link the schematic.
• List some part numbers in the 7 segment section. Referring to the "side" of the 7 segment will be weird for folks who wind up with a single display rather than a dual display.
