FPGA Logic Performance Characteristics

This section provides the performance characteristics of some common functions and designs implemented in the Artix UltraScale+ FPGAs. These values are subject to the same guidelines as the AC Switching Characteristics section.

In each of the following LVDS performance tables, the I/O bank type is either high performance (HP) or high density (HD).

In LVDS component mode:

For the input/output registers in HP I/O banks, the Vivado tools limit clock frequencies to 312.9 MHz for all speed grades.
For IDDR in HP I/O banks, Vivado tools limit clock frequencies to 625.0 MHz for all speed grades.
For ODDR in HP I/O banks, Vivado tools limit clock frequencies to 625.0 MHz for all speed grades.

LVDS receivers are typically bounded with certain applications to achieve maximum performance. Package skews are not included and should be removed through PCB routing.

Native mode is supported through the High-Speed SelectIO Interface Wizard available with the Vivado Design Suite. The performance values assume a source-synchronous interface. PLL settings can restrict the minimum allowable data rate. For example, when using the PLL with CLKOUTPHY_MODE = VCO_HALF the minimum frequency is PLL_F_VCOMIN/2. In the UBVA368 and SBVB484 packages, the maximum data rate is 1260 Mb/s for DDR interfaces and 630 Mb/s for SDR interfaces. LVDS receivers are typically bounded with certain applications to achieve maximum performance. Package skews are not included and should be removed through PCB routing. Asynchronous receiver performance is limited to 1300 Mb/s for -2 speed grades and to 1250 Mb/s for -1 speed grades.

1000BASE-X support is based on the IEEE Standard for CSMA/CD Access Method and Physical Layer Specifications (IEEE Std 802.3-2008).

The following table provides the maximum data rates for applicable memory standards using the Artix UltraScale+ FPGA memory PHY. Refer to Memory Interfaces for the complete list of memory interface standards supported and detailed specifications. The final performance of the memory interface is determined through a complete design implemented in the Vivado Design Suite, following guidelines in the UltraScale Architecture PCB Design User Guide (UG583), electrical analysis, and characterization of the system.
