Design and Constraints Impact on Compile Time - 2025.1 English - UG904

Compile time is impacted by the following factors:

• Netlist complexity and utilization
• Timing constraints and optimization

You can use the following Vivado tools features to reduce compile time:

Multi-threading

On multiprocessor systems, the Vivado tools use multi-threading to speed up certain processes, including DRC reporting, static timing analysis, placement, and routing. For more information, see Multithreading with the Vivado Tools.

Generate Parallel Reports

Allows you to generate certain reports in parallel to reduce compile time. For more information, see the generate_parallel_reports command in the Vivado Design Suite Tcl Command Reference Guide (UG835).

Quick Directive

Sets the absolute, fastest compile time for place and route. This directive applies to both place_design and route_design, is non-timing-driven, and performs the minimum compilation needed to place and route a design.

In addition, the performance of the compute host server is important in achieving efficient compile times, and optimizing the BIOS and CPU settings is essential for maximizing this performance. The following table outlines recommended settings for CPUs and servers, providing guidance on how to configure your system for optimal operation.
