Justin Zaun	9288889e20	gowin: add hardware latch support (DL/DLN/DLC/DLP variants) ... Add simulation models, techmap, and dfflegalize rules for Gowin DL-series latch primitives. Latches use the same physical BEL as DFFs with REGMODE set to LATCH. All 12 variants are supported: DL, DLE, DLN, DLNE, DLC, DLCE, DLNC, DLNCE, DLP, DLPE, DLNP, DLNPE.	2026-03-05 16:04:23 +01:00
