3.3.3 Compiling the generated code along with top level VHDL entity:

Add this ﬁle and all the *.vhd ﬁles produced by the SOPC Builder to your Quartus II project.

Also, add the necessary pin assignments on the DE2 board to your project. Pin assignments are

made by importing the assignments given in the ﬁle called DE2_pin_assignments.csv in the

directory DE2_tutorials\design_ﬁles, which is included on the CD-ROM that accompanies the

DE2 board and can also be found on Altera’s DE2 web pages. Having made the necessary

settings compile the code. On compiling this code a SRAM object file(.sof) is generated which is

used to program and configure the board.

3.4 Programming and Conﬁguration:

Programming and conﬁguring the Cyclone II FPGA in the JTAG programming mode is done as

follows:

1. Connect the DE2 board to the host computer by means of a USB cable plugged into the

USB-Blaster port. Turn on the power to the DE2 board. Ensure that the RUN/PROG switch is in

the RUN position.

2. Select Tools > Programmer

3. If not already chosen by default, select JTAG in the Mode box. Also, if the USB-Blaster is not

chosen by default, press the Hardware Setup... button and select the USB-Blaster in the window

that pops up.
