2.2.1. Programmable Output Slew Rate Control
For GPIO pins implementation, Intel® Agilex™ devices support only the fast slew rate setting for voltage-referenced I/O standards. For 1.2 V LVCMOS I/O standard, you can select between fast, medium, and slow slew rate settings.
For external memory interface pins implementation, Intel® Agilex™ devices support fast, medium, and slow slew rate settings when you instantiate the EMIF Intel FPGA IP in your design.
A faster slew rate provides high-speed transitions for high-performance systems while a slower slew rate reduces system noise and crosstalk but adds a nominal delay to the rising and falling edges.
