cosimulation with ISim/XSim/NCSim not available in VHLS for SystemC design

I am using Vivado_HLS 2012.4

 

when (HL)synthesizing from C there is a choice of simulators for cosimulation, including ISim, XSim and NCSim,

while in a systemC project only ModelSim, VCS and Riviera seem available.

 

is this "normal" for Vivado_HLS i.e. ISim is only available for cosimulation for C projects, or is it a result of my altering some setting or the project using unsupported systemC constructs/datatypes??

 

(systemC simulation of generated SystemC RTL works as well as "Setup Only" for ModelSim for systemC/Verilog/VHDL for the systemC project)

 

thanks in advance!

They are expected.

 

SystemC project has slightly different cosim flow than C/C++ project. Right now there are less simulators supported.

 

For the systemc rtl generated from C/C++ projects, actually they do not need any simulator for the simulation. The SystemC library supports that natively.
