How to initialise Port B in dual port ROM?

In Vivado 2017.3 I am able to initialise port A by editing memory. But for port B there is no option to do that, in the other options tab. I tried doubling the length or width of memory, but it gave validation error. If I cant initialise Port B memory then there is no use of a dual port ROM. I will have to make do with 2 single port ROMs.

Hi @TechWell 

Are you using the block memory generator ?

PORT A and PORT B shared the common memory so you only need to initialize memory using .coe file.

Please elaborate on how you are implementing the dual port ROM and how PORT A is initialized
