YRabbit	e9b7da5a0f	GOWIN. Fix DP when READ_MODE=1 Dual Port has a defective output register. This only manifests itself at small data widths and only on -C chips. That is, Tangprimer20k (GW2A-18) works perfectly, while Tangnano20k (GW2A-18C) stutters. The same story with GW1N-9 and GW1N-9C. Fortunately, the fix has long been included in nextpnr for SDP memory, so all that remains is to call the same function for Dual Port.

YRabbit	111f085d64	GOWIN. Fix dual port CE-OCE. We are fixing a hardware error - in BYPASS mode, dual port bsram requires synchronization of CE and OCE signals for some data widths. We are also getting rid of port renaming in the loop, but not all of them yet. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>	2026-03-09 12:23:01 +01:00
