Build Framework

Once app_sub.ngc has been copied to current ISE project folder, we are ready to build the framework and generate a bit file for FPGA download.

Perform following operations :

1. Start Xilinx ISE
   
   
2. Open CRKit project located at d:\hw\cr_build\cr_r3_sim\cr_r3.ise . The opened project should look like as shown in Figure 1.

Figure 1 - ISE cr_r3 project

3. You have the option to re-synthesize the framework. Note the application module e.g. app_sub.ngc is not synthesized at this stage, this has been done within MATLAB/Simulink. To synthesize the framework, right-click on Synthesize - XST in processes window, and select run or re-run. This step can be skipped if you already have synthesized the framework at an earlier stage, hence save some build time.
   
   
4. Proceed with the place/route stage. Right-click on Implement Design in processes window, and select run or re-run. Once this step is completed succesfully, you should see All Signals Completely Routed and All Constraints Met under the project status as shown in Figure 2.

5. Generate bit file. Right-click on Generate Programming File in processes window, and select run or re-run. Once this step is done, the bit file is available at d:\hw\cr_build\cr_r3_sim\cr_top.bit .
   

6. Use Xilinx Impact tool to download the bit file onto the FPGA.
   

7. FPGA is ready to transmit/receive Ehernet packets to/from host. Use your own host software application to do so. However, we do have a Visual Studio based software available on CRKit svn.
