2.10.10 Cascading FIFO Blocks

FIFO blocks can be cascaded to create deeper FIFO functions. When building larger FIFO blocks, if the word width can be fractured in a multi-bit FIFO, the fractured word configuration is recommended over a cascaded configuration. For example, 256x36 can be configured as two blocks of 256x18. This should be taken into account when, building the FIFO blocks manually. However, when using SmartGen, the user only needs to specify the depth and width of the necessary FIFO blocks. SmartGen automatically configures these blocks to optimize performance.
