src ipbus_transport_axi_if.vhd

src ipbus_transport_ram_if.vhd ipbus_transport_ram_if_simtb.vhd
src ipbus_transport_multibuffer_if.vhd
src ipbus_transport_multibuffer_cdc.vhd
src ipbus_transport_multibuffer_rx_dpram.vhd ipbus_transport_multibuffer_tx_dpram.vhd

src ipbus_axi_decl.vhd

?toolset=="Vivado"? src ../cgn/axi_bram_ctrl_0.xci

include -c components/ipbus_core 

... to ...

src ipbus_transport_ram_if_simtb.vhd
include ipbus_transport_axi.dep
