This board is replaced by new version of VHDL training board version 3, which enables more easy prototyping by FPGA

What is it?

VHDL (or verilog-HDL) learning board for beginner. It consists of CPLD and FTDI, which enables direct implementation upload. In addition, it has minimum and sufficient interfaces (tact switch, LEDs, and 7-seg LED and (optional, not populated) piezo-element speaker)

Additional information about REV.2 board is presented at my hackaday project page. please refer before ordering

Several sample .svf files are prepared at GitHub. Please use for your test.

Why did you make it?

We can find lots of commercial FPGA board but I still feel they are too powerful and too complicated for "real beginner". Here I made an alternative board having 7-segment LED and switches, piezo and on-board oscillator. Good point of this board is that, we can have "making from root by soldering" and nothing useless (because it is really simplified). Also, the cost will be very competitive. The CPLD on this board is very classical but it can still work for educational purposes since VHDL knowledge is common for both up-to-date FPGA and this CPLD. As same as my another project, the .svf file generated by Xilinx ISE can be uploaded through USB interface. You may think "obsolete" just to see CPLD but when we think the essence of learning hardware description language, CPLD or FPGA does not matter.

What makes it special?

• REV.1 (previous version) We can make this board from its root! (Semi-kit. lead-axial resistor, LEDs, transistors, 7-seg LED, piezo, switch, connectors should be soldered for completion)

• REV.2 Everything is soldered on board and ready to use.

• Very good price (just $15 (REV.2:$)20)

• REV.2: On board very slow (8 Hz, not 8 kHz, just 32768/4096=8 Hz) clock oscillator

• REV.1: All of required parts are packed in (including very special 8-DIP 32.768 kHz oscillator), all you will need is Windows machine and USB cable

• REV.2: All of parts are soldered. All you will need is Xilinx XSE installed Windows machine and USB cable,

• How to set up the VHDL Development environment is explained in the relevant hackaday project
