We will be converting the VGA design from last week into a module that we can reuse in other designs. The new module will make use of generics and a library that will contain settings for various VGA modes.

For those of you with a Nexys3, Basys2, or Atlys, you will be able to connect a VGA cable directly. For those using a Mojo or some other board without a VGA connection, please E-Mail [email protected] stating that you need a VGA breakout cable! There are several breakout cables from last class, but we need to make sure there are enough on hand.

The slides for the upcoming and previous classes can be found here. The slides are generally made during the three days before a class. An E-Mail will be sent to those attending the class via Google Hangouts with instructions for getting an SRAM chip.

Agenda:
1. Explanation of VHDL libraries
2. Overview of VHDL generics
3. Find out what parts of the VGA design are variable between modes
4. Using records in VHDL
5. Create a library that contains a single record for 640×480 @60Hz
6. Create and run a new design that uses the generic VGA module

If you would like to join the class, then please E-Mail [email protected]. The class is now to a point where you need to know VHDL prior to joining. We also stream the class on Google Hangouts. Please send an E-Mail to [email protected] if you would like to join the Google Hangout.

IMPORTANT You MUST have ISE (not Vivado!) installed prior to the start of class!!! ISE can take upwards of 30 minutes to an hour to install. We will not have time to wait for ISE to be installed. Please go to here and download the ISE Design Suite package for your operating system. If you have licensing or installation issues, please contact [email protected]

Required Items:
1. FPGA development board with Spartan 3 or Spartan 6
2. USB cable for programming
3. JTAG programmer if your board does not have USB
4. Laptop with ISE installed and either wired or wireless network connectivity
5. VGA breakout (red, green, blue, horizontal sync, vertical sync, and ground) if you do not have a VGA connector on your dev board.

Provided Items:
1. VGA breakout if you let the instructor know

We have been given ‘academic’ status from Digilent Inc (http://www.digilentinc.com). This means that the instructor can (sometimes) purchase boards from Digilent at the academic price. This discount will only apply to people who are attending the class regularly and is on a case-by-case basis from Digilent.

Since Unallocated Space runs off of donations, we would like to mention that the recommended donation for this class is $5. It is by no means a requirement! Attendance to the space, and this class, is 100% free to all!
