Description
You can allocate TriMatrix memory blocks two ways. The Quartus II software checks each functional memory instantiation in the design. If it is using the
ALTSYNCRAM
function, the "RAM_BLOCK_TYPE"
parameter will be checked.
- If the parameter is set to "AUTO," the default setting, the Quartus II software will automatically select what type of TriMatrix memory block to use.
- If the parameter is set to "M512", "M4K", or "M-RAM", the Quartus II software will implement the function using the stated resource.
For more information on this, please reference the Using TriMatrix Embedded Memory Blocks in Stratix & Stratix GX Devices chapter of the Stratix Device Handbook.
