Lattice renamed some IO primitives when moving from Diamond to Radiant. This is, naturally, sparsely documented but I found a reference in Table 41 of 1. One letter in the name of each primitives is changed, as well as one of the inputs (
i_SCLK->i_CK). This requires a different IO Buffer specialisation for Nexus (Radiant) compared to MachXO2 and ECP5 which this PR adds.I don't quite know which name Oxide would expect, but a quick grep among the fuzzing scripts finds the updated name (same as Radiant) and not the previous one. So I assume this change is applicable to Oxide also.
Support for Nexus was recently added in #1342
