Make sure Quartus II and Nios II are installed on your PC.
Connect the USB Blaster cable to the TR4 board and host PC. Install the USB Blaster driver
if necessary.
Power on the TR4 board.
Execute the demo batch file “Breathing_LEDs.bat” under the batch file folder,
TR4_Breathing_LEDs\Demo_batch.
Press
BUTTON0
of the TR4 board to reset.
The LEDs will pulse according to the set frequency.

The External Clock Generator provides designers with 3 programmable clock generators via Texas
Instruments chips (CDCM61001RHBT x 2, CDCM61004RHBT) with the ability to specify the
clock frequency individually, as well as addressing the input reference clock for the Stratix IV GX
transceivers. The programmable clock is controlled by a control bus connected to the MAX II
EPM2210 device. This can reduce the Stratix IV GX I/O usage while enabling greater functionality
on the FPGA device. The MAX II EPM2210 device is capable of storing the last entered clock
settings at which in the event the board restarts, the last known clock settings are fully restored. In
this demonstration, we illustrate how to utilize the clock generators IP to define the clock output
using the serial bus. The programmable clock outputs generate clock signals HSMA_REFCLK_p/n
(CDCM61001/01),
PGM_GXBCLK_p1/n1
(CDCM61004),
and
HSME_REFCLK_p/n
(CDCM61001/02) with adjustable output clock frequencies of 62.5, 75, 100, 125, 150, 156.25,
187.5, 200, 250, 312.5, and 625MHz. The I/O standard for the clock frequencies is set to LVDS
which is not configurable.
