• All Nexus / Radiant 2023.1 and older: How can the user calculate the Clock-To-Out (min and max) values and Input setup/hold values of the I/O Timing Analysis report?

  The Clock-to-Out max value is the setup analysis' arrival time of data with the output port's external timing path. The Clock-To-Out min value is the hold analysis' arrival time of data with the output port's external timing path. By default, timing ...

• All Nexus / Radiant 2023.1 or earlier: How are the clock-to-out max and clock-to-out min values on the I/O Timing Analysis report calculated?<div><br></div>

  Clock-to-out max corresponds to the arrival time of the data of the external timing path when setup time is analyzed. Clock-to-out min corresponds to the arrival time of the data of the external timing path when hold time is analyzed. If there are ...

  It is not recommended to change the default speed grade settings for both the Place & Route (PAR) Design and Place & Route Timing Analysis. DEFAULT VALUES: The default values (especially for HOLD) are for worst case timing calculations. For PAR ...

  For a multicycle constraint, -start and -end indicate to which clock (launch or capture clock) the constraint is referenced. Below is an example: Setting up the Example: Let's say we have a path from register coutr1_reg[5] to register coutr2_0io[4]. ...
