2.2.1. Design Constraint File No Longer Generated
For a new Triple-Speed Ethernet Intel® FPGA IP created using the Quartus® Prime software version 13.0 or later, the software no longer generate the <variation_name>_constraints.tcl file that contains the necessary constraints for the compilation of your IP variation.
The following table lists the recommended Quartus® Prime pin assignments that you can set in your design.
Pin Assignment | Assignment Value | Description | Design Pin |
---|---|---|---|
FAST_INPUT_REGISTER | ON | To optimize I/O timing for MII, GMII and TBI interface. | MII, GMII, RGMII, TBI input pins. |
FAST_OUTPUT_REGISTER | ON | To optimize I/O timing for MII, GMII and TBI interface. | MII, GMII, RGMII, TBI output pins. |
IO_STANDARD | 1.4-V PCML or 1.5-V PCML | I/O standard for GXB serial input and output pins. | GXB transceiver serial input and output pins. |
IO_STANDARD | LVDS | I/O standard for LVDS/IO serial input and output pins. | LVDS/IO transceiver serial input and output pins. |
GLOBAL_SIGNAL | Global clock | To assign clock signals to use the global clock network. Use this setting to guide the Quartus® Prime software in the fitter process for better timing closure. |
|
GLOBAL_SIGNAL | Regional clock | To assign clock signals to use the regional clock network. Use this setting to guide the Quartus® Prime software in the fitter process for better timing closure. |
|
GLOBAL_SIGNAL | OFF | To prevent a signal to be used as a global signal. | Signals for Arria® V devices:
