Altera IP megawizard plug-in manager....

[Altera_Forum]

Hi  

  Anyone aware of these terms...   1. Descriptor RAM 2. True Dual Port SRAM based FIFO    those are primities from Xilinx coregenerator, I need to generate the same using Altera Megawizard plug-in manager. Is there any alteranative names for Altera?   Thanks!

1) Not aware of an Altera block describing itself as descriptor memory 

2) The megawizard will do this if you select "memory compiler" then FIFO; then on page 3 ensure you select "No, synchronize reading and writing to 'rdclk' and 'wrclk' respectively" and then tell it whether the clocks are related or not.  Alternatively, the old primitive dcfifo will do what you want.
