The import "DPI" thing is how I'm supposed to tell my verilog
simulator what the C functions will look like.
This might be a problem with the verilog simulator (which is being a bear
to work with) but I just wanted to check if anyone recognized
the "'const' must be followed by 'ref'" message and saw something
stupid that I was missing?
Maybe their macro isn't tolerant of all legal C++ syntax. Try putting
the ampersand immediately after the 'const':
void Note( string const& msg);
HTH,
