CAN Protocol Controller

I am building a CAN controller project on an actel Proasic 3 chip using this core, but the developping software Libero cannot recongnize the module "actel_ram_64x8_sync, actel_ram_64x4_sync, actel_ram_64x1_sync" and I cannot find any information about this three module on actel website, either. Is this core can only be applied on certain FPGA of ACTEL, or the three module should be created by myself? What is the exact reason of this problem?

You have to generate your own Makros for these entities using the IP Core Generator inside your Libero Tool. I should be located on the rightern side of your Libero project window.
