Timing: The I/O Timing Report is a used to analyze the the IO timing in your design (Tsu, Th, Tco). The IO Timing Report sweeps across all the speed grades to determine the worst case.
Lattice ispLEVER: Timing Analysis: The I/O Timing Report (.ior) is a used to report the IO timing analysis of your design. Input Setup and Hold times (Tsu, Th) and Clock-to-Output times (Tco) are reported. The IO Timing Report sweeps across all the ...
For I/O timing analysis, the "Clock Port" column/field could refer to the following depending on the destination clock: 1. Internal oscillator clock: If the destination clock is directly from the internal oscillator, or if the destination clock is ...
The result from .PAR and from .TWR is expected to be different. For Radiant 2023.2, multi-corner timing analysis is implemented, the idea is for: A. 2023.2 1) PAR Timing Analysis (.PAR) - The Timing model used is the model with "WORST" case at ...
When user change the PLL phase to improve the Tco, user caan program the PLL phase delay by more than 180 degree, e.g. 315 degree. Its equivalent effect is to advance 45 degree if one clock cycle latency is acceptable. But the Lattice software will ...
The M or Minimum Speed grade device appears to be faster than the fastest speed grade in the I/O timing report and the term "Minimum Speed grade" can be a bit confusing. For starters, it does NOT mean the slowest silicon device. The term refers to ...
