virtual expand

The virtual expand command produces a list of all the non-virtual objects

contained in the virtual signal(s). This can be used to create a list of arguments for

a command that does not accept or understand virtual signals.

Syntax

virtual expand

[-base] [<path>|<wildcard>]+

Arguments

-base

Causes the root signal parent to be output in place of a subelement. Optional. So

for:

power add [virtual expand -base myVirtualSignal]

the resulting command after substitution would be:

power add signala signalb signalc

Examples

power add [virtual expand myVirtualSignal]

Adds the elements of a virtual signal to the power reporting tool.

In the Tcl language, the square brackets specify that the enclosed command should

be executed first ("virtual expand ..."), then the result substituted into the

surrounding command. So if myVirtualSignal is a contatenation of signala,

signalb.rec1 and signalc(5 downto 3), the resulting command after substitution

would be:

power add signala signalb.rec1 {signalc(5 downto 3)}

The slice of signalc is quoted in curly braces automatically because it contains

spaces.
