Hi,

I am not able to find information related to this error and could not duplicate the error as well.

Could you help to share the project that could duplicate this error? A simplified project will do.

Hi Richard, Please see attached a simplified version. Since then I found that “true_dual_port_ram_single_clock” does infer, but still it looks as the RAM doesn’t work. I have replaced for synchronous and a- synchronous version q_b <= ram(addr_reg_b); with q_b<= x"AA"; and does read out, so seems that the MUX and signals to read out works. Thanks, Regards, Stel
