The left side of this window shows the block diagram of the module. The right side includes the Configuration tab
where users can choose options to customize the RAM_DP such as (e.g. specify the address port sizes and data
widths).
Users can specify the address depth and data width for the Read Port and the Write Port in the text boxes pro-
vided. In this example we are generating a Pseudo Dual Port RAM of size 512 x 16. Users can also create the
RAMs of different port widths in case of Pseudo Dual Port and True Dual Port RAMs.
