[Bug 460241] [NEW] ghdl diagnostics might be improved

[Sinisa Segvic]

Public bug reported:

Binary package hint: ghdl

In order to test a vhdl design in our environment with ghdl, one should
say:

ghdl --elab-run --std=00 --ieee=synopsys MyComponentTB

This works nicely, however, my students often make a mistake 
by specifying the *component file* instead of component name:

ghdl --elab-run --std=00 --ieee=synopsys MyComponentTB.vhdl

ghdl then aswers with:

/usr/lib/ghdl/bin/ghdl:*command-line*: bad character in identifier

And that's game over for my students, they then start 
to complain about ghdl in general, and propose 
doing their work only in Xilinx' software.

My suggestion would be to print an additional help message,
such as "did you specify a file name instead of the component identifier?",
before the correct complaint about a bad character '.'.

Cheers,

Sinisa
