Running Implementation - 2023.1 English

The Vitis HLS tool is limited in terms of the estimations it can provide about the RTL design that it generates. It can project resource utilization and timing of the end result, but these are just projections. To get a better view of the RTL design, you can actually run Vivado synthesis and place and route on the generated RTL design, and review actual results of timing and resource utilization. Select the Run Implementation command from the Flow Navigator to open the dialog box as shown below.

Figure 1. Run Implementation

The dialog presents the choice of running RTL Synthesis or RTL Synthesis, Place & Route. The dialog box is largely unchanged in either selection, with the exception of the Place & Route Options that appear at the bottom.

RTL

Generate RTL in Verilog or VHDL form.

Clock Period

Specify the clock period, which is defined by the active solution by default.

Generate DCP

Check box to generate a DCP file for the synthesized or implemented design.

IP Location

Specify the location to write the generated IP file.

IP OOC XDC File

Specifies an XDC file to be used for the RTL IP for out-of-context (OOC) synthesis.

IP XDC File

Lets you specify an XDC file for use during Vivado place and route.

Report Level

Defines the report-level generated during synthesis or implementation.

Max Timing Paths

Specify the number of timing paths to extract from the Timing Summary report. The worst case paths are returned as defined by the specified value.

RTL Synthesis Strategy

Specify the strategy to employ in the synthesis run.

Synth Design Arguments

Specify options for the synth_design command.

Run Physical Optimizations

Specify the physical optimization to run. Choices include: none, place, route, and all

Implementation Strategy

Specify the strategy to employ in the implementation run.
