General Procedure for VB Testing 1. Connect the VLSI platform (ST102A) with power supply and JTAG cable.

2. Connect the JTAG cable to PC 3. Turn on the Power Supply

4. Now follow the procedure as shown in the figures below: Go to Start Menu/ All Programs / Xilinx ISE / Accessories / Impact

Figure 3

Then the following window shown below will appear on the screen.

Figure 4

Select Create a new project (.ipf) and then press “OK”. As shown below.

Next Window appearing on the screen is as shown below.

Figure 6

Select “Configure devices using Slave Serial mode” and then press “Finish”.

Figure 7

Now the following window shown below will appear on screen. Here impact will ask to “Add Device”. This is the position were the “.bit file” for the particular “VLSI Board “has to be assigned.

Figure 8

Now go to the VLSI Solution Folder, and then select the VLSI platform (ST102A) on which you have to program.

Figure 11

Then open the VB folder which you are testing (For example here I have chosen VB7 RTC). The following window will appear. (this window consist of the “.bit” file which you have to assign.)

Figure 12

Now click on the “Open” button of the window. The next window appearing on the screen will be as shown below:

Figure 13

Now verify the device and the .bit file in the window shown above according to the VLSI platform you are using and the VB you are testing. (For example as in this case VLSI platform used is ST102A, therefore device is xc2s50 and VB is VB7 RTC therefore bit file is rtc. bit as shown in above figure). Again check the power supply connected to the board and is in “ON” Position and check the JTAG cable connected to the PC. Now right click on the device and then click “Program”.

Figure 14

After the device is programmed an indication in BLUE will appear on the screen denoting “Program Succeeded”. Now test the specific VB by connecting it to the VLSI platform and the specific testing procedure mentioned in the VB manual.

Theory

Led Flasher is a design that comprises of sixteen LED outputs with five change modes for LED flashing and with selectable frequencies of flashing. The system clock governs the whole process and act as the main clock for the design. A reset switch to initialize the system is provided and a push button switch to change the mode is also included. The five different modes of LED Flasher are:

• Mode 1- Left to right motion (Default)

• Mode 2- Right to left motion

• Mode 3- Odd Even type.

• Mode 4- Top Bottom row wise.

• Mode 5- Top-bottom individual (First of top row then first of second row) Other Specific features of the design are that it uses the DIP switches for frequency control and power on reset will display mode 1. Also mode can be selected any time.

Testing Procedure for VB 8 (LED Flasher) with ST102A Step 1: Program the device as mentioned in the “General Procedure for VB testing” with bit file of VB8 named “led_flasher.bit” located in the “VLSI Solution”.

Step 2: Connect VB8 to J5 40 pin connector and display will be on. Test Supply voltage on TP1 (VCC) with reference to TP2 (GND) approx. 5V.

Step 3: Press the “Master Reset” switch (SW 2) on the board to initialize the flasher to Mode 1 of display Flasher remains in a mode for few seconds (10 seconds approx.)

Step 4: In order to change mode press “Flash Mode Change” (SW 3) switch on the board.

Step 5: Use the “Frequency Select” (SW 1) switch to change the frequency of flashing.

Step 6: The Five modes of flashing can be seen on the board.

• MODE 1 - LEFT to RIGHT

• MODE 2 – RIGHT to LEFT

• MODE 3 – ODD EVEN Type

• MODE 4 – TOP BOTTOM row wise

• MODE 5 – TOP BOTTOM individual (First of Top row then first of second row)
