6947 - Radiant: How can users reduce the high delay value on the output pad?
To reduce the delay on the output pad, users can use the FAST slew rate option on the Device Constraints Editor instead of the SLOW (default) or MED value.
The training logic sets the delay value of OUTDELAYA primitive during training. The Radiant Timing Engine cannot set the delay value, so users should not add set_output_delay constrain on the Output Port.
Description: In synthesis, the user may encounter this warning if the synthesis tool skips the IO pad insertion when a 'black_box_pad_pin' attribute is found on the port. Solution: Users may refer to the following from Radiant Help for ...
In Spreadsheet View, users can define the differential signal as LVDS I/O type, then assign the signal (i.e., the positive side) to a true pad. The software ispLEVER or Lattice Diamond or Lattice Radiant will automatically assign its negative side to ...
Description: We do not have a linter feature on Radiant. The RTL code is checked by the software when either updated or has been inserted in the project and then gives the appropriate message result (info/warning/error) on the output window. ...
Below is a step-by-step explanation on why the default operating temperature in TCL+ defaults to -1C and observe its effect on timing analysis: 1. When you open the PAR-generated UDB file using des_read_udb and run des_report_operating_condition, the ...
