VHDL settings tab
The VHDL tab includes these options:
Generics
The Add button opens a dialog box (shown below) that allows you to specify the value of generics within the current simulation; generics are then added to the Generics list. You can also select a generic on the listing to Delete or Edit.
From the Specify a Generic dialog box you can set the following options.
- Generic Name (-g <Name>=<Value>)
The name of the generic parameter. Type it in as it appears in the VHDL source (case is ignored).
- Value
Specifies a value for all generics in the design with the given name (above) that have not received explicit values in generic maps (such as top-level generics and generics that would otherwise receive their default value). The value must be appropriate for the declared data type of the generic parameter. No spaces are allowed in the specification (except within quotes) when specifying a string value.
- Override Instance - specific Values (-G <Name>=<Value>)
Select to override generics that received explicit values in generic maps. The name and value are specified as above. The use of this switch is indicated in the Override Instance column of the Generics list.
The OK button adds the generic to the Generics listing; Cancel dismisses the dialog box without changes.
VITAL
- Disable Timing Checks (+notimingchecks)
Disables timing checks generated by VITAL models.
- Use Vital 2.2b SDF Mapping (-vital2.2b)
Selects SDF mapping for VITAL 2.2b (default is Vital95).
- Disable Glitch Generation (-noglitch)
Disables VITAL glitch generation.
TEXTIO files
- STD_INPUT (-std_input <filename>)
Specifies the file to use for the VHDL textio STD_INPUT file. Use the Browse button to locate a file within your directories.
- STD_OUTPUT (-std_output <filename>)
Specifies the file to use for the VHDL textio STD_OUTPUT file. Use the Browse button to locate a file within your directories.
