This is the sixth video in a sub-series on building a VGA interface for the HackCPU computer using Logisim Evolution. I build the Screen component described on page 90 of The Elements of Computing Systems, in preparation to put the VGA interface under Hack computer control. I demonstrate a test circuit that progressively fills the screen by writing values to RAM running on a Digilent CMOD A7.

You will need the develop branch from Logisim Evolution in order to pick up the board design for the CMOD A7, as well as obtain the clock synthesis feature I added to Logisim, until such time as my changes make it into a Logisim release.
You will need the Vivado product from Xilinx to synthesize the design for the Digilent board. It's huge, but free (if you give your information). Sorry. I did not write it.
