Hello Does NCVHDL expect top level design as configuration? This could be related to IEEE compliance. I have two vhd files - a module and it's testbench. The module elaborates fine but does not simulate on Simvision unless at top level I use another vhd file with configuration for binding the module i.e., the design project becomes three files. Is it possible to simulate a module with it's testbench without configurations? I'm on 05.70-s005. Yaseen
