In the video titled "chipIgnite update & AI designed ASIC competition" form efabless YouTube channel, it is stated that OpenRAM usage is not suggested, instead DFFRAM is suggested. (at 25:41) Is it still the case? We are planning to submit a tapeout for Chipignite (CI 2309), so do we have to use DFFRAM instead of OpenRAM? Or is there any other alternative? Thanks,
