FIFO Generator - Built-In FIFO is not supported in Spartan architectures, only in Virtex architectures

Description

When using Spartan-6 architectures, it is not possible to use Built-In FIFO implementation in the FIFO Generator GUI.

The feature is grayed out.

This option is available for all Virtex families but not for Spartan-6, why is this the case?

Solution

This is because Spartan-6 does not have a built-in FIFO primitive.

It is only available on Virtex-4, Virtex-5 and Virtex-6.

This information is contained in the Datasheet for the core.
