Radiant 2023.2 and below: How to create a design-specific BSDL for Nexus devices?
You can create an application-specific BSDL file using Radiant Deployment Tool. However, the tool only supports specific BSDL files that target non-volatile memory (using *.jed file), which is inapplicable for Nexus devices that target SRAM (*.bit).

Lattice Nexus devices using Reveal: no output from LVDS IP
Description: While debugging your Radiant design using Reveal, users may observe that there is no output from their LVDS IP. Solution: When Reveal is inserted in Nexus devices, on certain designs, the GSR net gets assigned to a reset signal that may ...
Radiant 2023.1: Why is the 'create_clock' constraint excluded from FDC?
Description: After evaluating the fix in Radiant 2022.1 for DNG-15807, the create_clock constraint in *.fdc still persists, and upon checking, the design has an unmatched constrained object in *.ldc and *.vm in which the mismatch happens before ...
Radiant: When to use a create_clock or create_generated_clock constraint? What are the consequences if a create_clock constraint is used instead of a create_generated_clock constraint?
Use create_clock constraints when the clock is coming from an input port. Use create_generated_clock constraints when the clock is generated from a module or circuit inside the FPGA design through multiplication or division of a base clock. The ...
<div>All Nexus / Radiant version 2023.1 or earlier: Is it correct to think that STA is performed under worst-case conditions for both setup/hold for Nexus Devices?<br></div>
Radiant timing analysis is performed under worst-case conditions for both setup/hold. As an example, consider the Nexus devices. By default, hold analysis is performed using the ‘m’ speed grade which represents the highest performance grade using the ...
