ModelSim: Warning: NUMERIC_STD."=": metavalue detected, returning FALSE

Hi, I'm having trouble with a testbench I wrote. When I include a particular 'if' statement, the design compiles/synths, then I run the functional simulation in modelsim, and get: Warning:...

Yes, this will likely be signals inside the design being uninitialised, and fairly normal. So normal and annoying, there is an option to turn warnings like these from numeric_std off.

Simulation -> runtime options -> "suppress warnings" from Synopsys Packages (from std_logic_unsigned/arith) From IEEE packages (numeric_std)

If you're running from a script, set these variables before the run command: 


set StdArithNoWarnings 1
set NumericStdNoWarnings 1
