Synthesizable Version of the HERO Project Accelerator

[ajgaspar]

When trying to run the setup for RTL simulation of the HERO Project's accelerator through synthesis, two modules are not synthesizable, namely axi_sim_mem and apb_stdout. Are there preexisting versions of these two modules that will pass synthesis, or would I just have to try and make them synthesizable while trying to maintain the default functionality as much as possible? TIA
