Occasional ContributorQuartus II 12.1 (64-bit). FIFO IP can only set the memory block type to Auto or M9K. When we choose Auto, it will still use M9K. How to constrain Cyclone 4 FIFO to use MLAB only? Thanks!
Super ContributorIf the IP does not allow you to select MLAB, which means the IP does not support it. It might be due to
1) performance issue using the fifo on Mlab.
2) the device itself does not have Mlab.
However, check on the latest version of Quartus to see if they are any changes.
Occasional ContributorHi Kenny
can I use qsf to constrain it ? such as "set_parameter -name ram_block_type MLAB -to <entity>" or "set_global_assignment -name BLOCK_RAM_TO_MLAB_CELL_CONVERSION <value>". Can I use Logic Cell to realize FIFOs?
Super ContributorThose usually was use for normal coding but not megawizards. You can try it but I doubt it can work.
