Hide warnings during Modelsim Simulation

The modelsim.ini file has a couple of parameters that allow warnings from the libraries to be suppressed, eg.,

<QUARTUS>/modelsim_ase/modelsim.ini

Make the file writeable, then edit:

; Turn off warnings from the std_logic_arith, std_logic_unsigned
; and std_logic_signed packages.
StdArithNoWarnings = 1
; Turn off warnings from the IEEE numeric_std and numeric_bit
; packages.
NumericStdNoWarnings = 1

There's a few other flags in there, but these two are all I've ever had to suppress.

Make modelsim.ini read-only again. This ensures the 'master' copy is clean (projects will create a local copy if they cannot write to the master copy).

There's also a +nowarn argument to vsim. I recall seeing that set in some of the SOPC .do files for verilog simulation. The argument can be used to suppress numbered warnings, eg., +nowarnTFMPC +nowarn3009.

Greetings. I checked the .ini file and both the options are marked 1 but I still get a barrage of warnings that show up on my transcript window in Modelsim.

Thank you

Afaik, if the warnings are not from std_logic_arith/usigned/signed or numeric_std, you cannot turn them off. There is usually a good reason that these warnings are firing - the only way to fix them is to fix the cause of the warnings (unless the coder who wrote the code was a numpty)

You cant even turn off the ones in the fixed point packages, which are basically the same as the ones in numeric_std.

A few examples of the warnings would help :)
