You're welcome!
Thanks! Feel free to use any design ideas you like.
For your board, what are your plans for programming? Will you expect your users to use an external USB-Blaster?
An alternative would be to use an FTDI FT232H in MPSSE mode. If you've never heard of MPSSE it stands for Multi-purpose synchronous serial engine. You can use it to implement JTAG, I2C, SPI, etc. Unfortunately an MPSSE interface would not be supported by Quartus as a USB-Blaster, but at least your users would not be faced with the problem of buying a low-cost FPGA board, but then having to spend $50 to buy a Terasic USB-Blaster. The Arrow BeMicro uses an FT2232H as an "Arrow-USB-Blaster", however, the driver and implementation is intended only for use with the Arrow board.
You can also implement an on-board USB-Blaster, however, that requires an FTDI chip plus MAX II, or a Cypress EZ-USB FX2 USB microcontroller (or porting of the clone code to a newer microcontroller).
Cheers,
Dave

The board already got a USB Blaster clone. I like that more than FTDI because user can debug and use the Quartus Interface. The board also got a USB 1.1 tranceiver for the user be able to create interfaces with the computer out-of-the-box. Thank you for the recomendation.
Best regards,
