8.4. Early I/O Timing Estimation

Early I/O timing analysis allows you to run I/O timing analysis without first compiling your design. You can use early I/O timing analysis to quickly evaluate whether adequate timing margin exists on the I/O interface between the FPGA and external memory device.

Early I/O timing analysis performs the following analyses:

  • Read analysis
  • Write analysis
  • Address and command analysis
  • DQS gating analysis
  • Write leveling analysis

Early I/O timing analysis takes into consideration the following factors:

  • The timing parameters of the memory device
  • The speed and topology of the memory interface
  • The board timing and ISI characteristics
  • The timing of the selected FPGA device
