NoC Emulation - 2021.2 English

NoC emulation support is provided with behavioral models in either SystemVerilog or SystemC. The simulation time with the SystemC model is much faster but is cycle approximate and less accurate compared to the SystemVerilog model.

Note: You can select your preferred simulation model using the IP Project Settings. Use the rtl setting for SystemVerilog and the tlm setting for SystemC. These settings apply to the entire project.

Although you can use both the SystemC and SystemVerilog models to verify functionality, the SystemVerilog model is recommended for performance analysis. Performance analysis using the SystemVerilog model is within ±5% of hardware.

You can emulate the NoC using simulators in the Vivado tools or using the hardware emulation flow provided by the Vitis environment.

Important: For more information the NoC simulation settings and performance tuning, see this link and this link in the Versal ACAP Programmable Network on Chip and Integrated Memory Controller LogiCORE IP Product Guide (PG313).
