Requesting for an Actel Library

Hi,

I am a student,I am new in VHDL and want to implement a project. I am working on VHDL with Actel Libero. In my previous implementation, I have used the "RAMB4_S1_S1"(4K-Bit Data Dual Port Block RAM) and "RAMB4_S1"(4K-Bit Data Single Port Block RAM) which are implemented in the "UNISIM" in Xilinx. Could you please provide me with the information of an equivalent library that implement these RAMs in Actel Libero ?

Thanks in advance

Best regards
