Hi,

 

May I know what device you are using? What is the cs you are referring to?

 

Thanks.

Hi,

 

If you instantiate larger memories block, the blocks will be automatically concantenated to build the bigger memory. If your port width configuration (either the depth or the width) is more than the amount an internal memory block can support, additional memory blocks (of the same type) are used. For example, if you configure your M9K as 512 × 36, which exceeds the supported port width, two 512 × 18 M9Ks are used to implement your RAM. 

 

Thanks.

Best regards,

KhaiY
