• Radiant: Does Radiant perform static timing analysis (STA) on reset pins/signals?

  Radiant performs static timing analysis (STA) on reset pin/signals that are using Local Set/Reset (LSR). To use LSR, user need to make sure that the GSR-related strategy settings are False/OFF (Force GSR on Synthesis and Infer GSR on MAP). User also ...

• Lattice Radiant: Why does the constraint coverage did not improve after using set_false_path constraint?

  By Default, set_false_paths does not improve constraint coverage, however For Radiant 2023.1 or later, the user can use the Timing Command Line Option "-false_covers" to add in the false paths to the timing coverage. This can be applied on the ...

• Radiant version 2023.1 or newer: Are there priority rules when multiple timing exception constraints are applied on a specific timing path?

  Kindly refer below to the exception priority: 1. set_false_path 2. set_max_delay or set_min_delay 3. set_multicycle_path A couple of notes: 1. set_max_skew applies to the timing path together with exception constraint that takes priority. 2. ...

• Lattice Radiant: How do i constraint a path with false path at Pre-Synthesis?

  It is not recommended to constraint from pin to pin in pre-synthesis path thus set_false_path may not be applicable. Instead, use post-synthesis path to do the set_false_path constraint. (use PDC)
