To address the different needs in simulation scope, abstraction, and purpose, AMD provides dedicated flows for the various components of an AMD Versal™ device design, including the AI Engine, PS, and PL. In addition, AMD also provides the ability to co-simulate a complete system comprised of PL, PS and optionally AI Engine components. Individual design teams must validate functionality at the function level prior to integrating in a subset of the system application or the complete system.
The following table shows the simulation models available for each Versal device block.
| Block | Cycle Accurate | Performance |
|---|---|---|
| PS | QEMU (functional only) | QEMU (functional only) CIPS Verification IP (VIP) |
| NoC | Behavioral SystemVerilog (cycle approximate) | SystemC |
| DDRMC | Behavioral SystemVerilog | SystemC |
| HBM controller | Behavioral SystemVerilog | Behavioral SystemVerilog |
| PL-based soft memory controller | Behavioral SystemVerilog | Behavioral SystemVerilog |
| CPM | Behavioral SecureIP | Behavioral SecureIP |
| GT | Behavioral SecureIP | File I/O (for Vitis software platform users only) |
| GT-based IP | Behavioral SecureIP | AXI verification IP File I/O (for Vitis software platform users only) |
| HLS-based IP | RTL | RTL |
| Other IP | Varies by IP | Varies by IP |
| PL | Behavioral Verilog VHDL SystemVerilog |
Behavioral Verilog VHDL SystemVerilog |
| AI Engine | SystemC (cycle approximate) | SystemC |
The following sections provide details on the scope and purpose of each of the simulation flows.
