Quartus® Prime Pro Edition: Version 25.1.1 Software and Device Support Release Notes
1.2. Changes to Software Behavior
The fast simulation models, initially introduced in Quartus® Prime Pro Edition software version 24.3.1, are now the default simulation models for IP example designs targeting Agilex™ FPGA portfolio devices, except for the following IP:
- Intel® R-Tile for Compute Express Link Solution
- AXI Multichannel DMA IP for PCI Express
- DisplayPort IP
The fast simulation models are currently supported only for Agilex™ FPGA portfolio IP on Siemens EDA QuestaSim* and Synopsys VCS* . For more information, refer to How do I use the fast simulation models to improve the simulation time in the Quartus® Prime Pro Edition software version 24.3.1 onwards?
- If there are critical warnings about pins missing Location or I/O Standard assignments, the Quartus® Prime Pro Edition software no longer generates programming files.
For details about pins that are missing these assignments, refer to the I/O Assignment Warnings report in the Fitter Plan stage.
For pins that are missing Location or I/O Standard assignments, add the appropriate assignments, and recompile the design.
