5916 - [iCE40 UltraPlus]: Can we generate IBIS models using Diamond, Radiant, and iCEcube2 Software?
Definition:Yes, Radiant and Diamond Software gives you the ability to generate IBIS model based on the user's design. Simply check "IBIS Model" in the Export options. After Export, the IBIS model can be found in the implementation folder. Unfortunately, IBIS models cannot be generated using iCEcube2. However, general IBIS models for all iCE40 devices can be found on our website.
