VHDL compiler options page
• Use 1993 language syntax
Specifies the use of VHDL93 during compilation. The 1987 standard is the
default. Same as the -93 switch for the vcom command
(CR-106). Edit the
VHDL93
(A-260) in the modelsim.ini to set a permanent default.
• Don’t put debugging info in library
Models compiled with this option do not use any of the ModelSim debugging
features. Consequently, your user will not be able to see into the model. This
also means that you cannot set breakpoints or single step within this code. Don’t
compile with this option until you’re done debugging. Same as the -nodebug
switch for the vcom command
(CR-106). See "Source code security and -
nodebug"
(C-292) for more details. Edit the NoDebug (A-261) in the modelsim.ini
to set a permanent default.
• Use explicit declarations only
Used to ignore an error in packages supplied by some other EDA vendors;
directs the compiler to resolve ambiguous function overloading in favor of the
