It is large, and simulation will be slow! Please read instructions in the writeup before using it. A tester for the full 640×480 resolution is available ( displaydriver_640x480_test.sv).Display parameters for VGA monitor: display640x480.vh.Verilog template and tester: vgadisplaydriver.sv and displaydriver_10x4_test.sv.Constraints files (for both types of boards): clock.xdc and vga.xdc.Simulation should look like this and this.NOTE: A sync polarity of “1” means a negative sync pulse (i.e., normally “1”, but goes down to “0” during the sync). Display parameters (type is “Verilog header” file): display10x4.vh.Verilog template and tester: vgatimer.sv and vgatimer_10x4_test.sv.

Powerpoint slides on VGA Displays, and a good reference for VGA display timing.Sequential Design: VGA Displays (Sep 9).Read the appropriate reference manual for your board: Nexys 4, Nexys 4 DDR, or Nexys A7.segdisplay.xdc (for Nexys 4) and segdisplay_DDR.xdc (for Nexys 4 DDR and A7).switches.xdc (for Nexys 4) and switches_DDR.xdc (for Nexys 4 DDR and A7).If different files are needed, the first one provided will work with Nexys 4 boards only (e.g., switches.xdc), and the second one with “DDR” in its name will work for both Nexys 4 DDR boards and Nexys A7 boards (e.g., switches_DDR.xdc).

Pin assignment (constraints) files: If only one version of a constraint file is provided (e.g., clock.xdc), it will work for all board versions.

Verilog files: dec7seg.sv and segdisplay_demo.sv.

Test fixtures: CounterMod4_test.sv, CounterMod7_test.sv, CounterMod7Enable_test.sv and xycounter_test.sv.

But the next lab will go back to the Wed-Wed cycle.

Due Date: Because of Labor Day and Well-Being Day on Sep 5th and 6th, the due date for this lab is moved from Wed to Fri Sep 9.
