value

formats

You can use the following format specifiers to specify the formats:

• %c: character
• %s: string
• %b: binary
• %d: unsigned decimal
  

  Use the -signed option to print the value as a signed decimal value.

• %o: octal
• %x: hexadecimal
• %h: same as %x
• %f: floating-point number
• %e: real number in mantissa-exponent form
• %g: use %e or %f, whichever is shorter
• %t: decimal time scaled from the timescale of the object's module to the simulation's timescale
• %v: strength value—wires only

To revert to the default format, use %.

If no format is specified, the default format depends on the object type. The following are the default formats:

• %d: time

• %d: integer

• %g: real

• $vlog_format87: reg
• $vlog_format: wire

The $vlog_format is a predefined Tcl variable that defaults to %h. You can set this variable to %b, %o, or %d.

For VHDL, values are returned in a format that resembles the appropriate VHDL syntax for the object type. If one of the radix format specifiers (%b, %o, %d, or %x) is given, the format affects the format of integer values and of bit and std_logic values. The value is shown without any added VHDL syntax, such as double or single quotes. Otherwise, the format specifier is ignored for VHDL values. The VHDL literal format (%v) is the default format. For example:

xcelium> value :vector
"101010111100"
xcelium> value %b :vector
101010111100
xcelium> value %h :vector
ABC
xcelium> value :enum
'1'
xcelium> value %d :enum
1
xcelium> value %b :enum
1

The value of a digital net that is associated with a mixed signal depends on whether the enclosing module is an ordinary module or a connect module. The value of a digital net within an ordinary module is the resolved value of the connect module drivers that drive the net. The value of a digital net within a connect module is the resolved value of the ordinary module drivers that drive the net. See "Driver-Receiver Segregation".

You can also use the pound sign (#) as a shortcut to the value command. When used on an analog branch, the # shortcut accesses the potential across the branch, not the flow.

You can use wildcard characters in the argument to a value command. 

• The asterisk ( * ) matches any number of characters.

• The question mark ( ? ) matches any one character.

You cannot use wildcard characters inside escaped names

-potential

Returns the potential of analog branches that are specified on the command line immediately following the -potential option. This option is ignored for any other kind of object.
