3.5. Generate GTS EHIP Design Example
To generate a design example for your IP variant, follow these steps:
Figure 9. Procedure
- On the IP tab, specify the parameters for your IP core variation. For the specific IP parameter settings, refer to Selected IP Parameter Settings table in simulation, compilation, and validation sections.
- Specify the parameters in the Example Design tab as shown in the image.
Figure 10. Design Example TabBy default Enable fast simulation parameter is enabled for AN/LT design under Simulations Options tab. In your design example testbench, you can utilize the Fast Sim model to reduce the IP simulation time.
Table 15. Design Example Parameters Parameters Value Default Description Auto-Negotiation and Link Training Options Tab Enable auto-negotiation and link training - Enable
- Disable
Disable When selected, the IP includes additional soft logic to perform Auto-Negotiation and Link Training (AN/LT). Available Example Designs Select Design - Single Instance of IP Core
- None
Single Instance of IP Core
Selects the number of instance of IP core for example design. For Dynamically Reconfigurable mode, only the Single Instance IP Core is available.
Example Design Files - Simulation
- Synthesis
- Simulation
- Synthesis
Simulation option generates the testbench and compilation-only project. Synthesis option generates the hardware design example.
Generated HDL Format Tab Generated File Format - Verilog
- VHDL
Verilog
Select the HDL files format. If you select VHDL, you must simulate the testbench with a mixed-language simulator. Target Development Kit Tab Board None None
Target development kit option specifies the target development kit used to generate the project. Ensure the pin assignments in the .qsf file are appropriate. Select Device Initialization Clock - OSC_CLK_1_25MHZ
- OSC_CLK_1_100MHZ
- OSC_CLK_1_125MHZ
OSC_CLK_1_125MHZ Selects the Device Initialization Clock. Enable Signal Tap Option Disable Disable Enable this option to include debug signals into the Signal Tap file in the generated design example.
- Click the Generate Example Design button.
- Once the design example is generated, click the Launch Example Design in Quartus.
The software generates all design files in sub-directories. You require these files to run simulation and compilation. For information on simulation, compilation, and validation of each variant, refer to the desired chapter.
