inffering RAM64X8SW and RAMB18E2 (ADDRENA, ADDRENB ) ultrascale Vivado 2016.4

I want to inferred new ultrascale primitives RAM64X8SW and RAMB18E2 (with support for ADDRENA and ADDRENB ports) in Vivado 2016.4. Is that possible?

 

In attached file there is a behavioral model of RAM64X8SW and RAMB18E2 (supposed to inffer to RAMB18E2 with ADDRENA/ADDRENB ports). The simulation of single_port_RAM64X8SW module and simulation of RAM64X8SW module from unisim library for the same stimuli vector (same tb) are identical.

 

Has Vivado support for inferring this primitives with proper settings?

Attached corrected files with RAMB18E2 (instance and inference) with the identical simulation results for the same stimuli vector (non-conflicting adresses).

Why in RAMB18E2 (inference) after synthesis there is no support for addrena/addrenb ports?
