virtual log

The virtual log command causes the sim-mode dependent signals of the specified virtual signals to be logged by the kernel. If wildcard patterns are used, it will also log any normal signals found, unless the -only option is used. You unlog the signals using the virtual nolog command.

Syntax

virtual log

[-kind <kind>]|[-region <path>] [-recursive] [-only] [-in] [-out] [-inout] [-internal] [-ports] [<signalName>|<pattern>]

Arguments

-kind <kind>

Specifies a subset of virtuals to look at. Optional. <kind> can be any of the following: signals, functions, designs, implicits, and explicits. Unique abbreviations are accepted.

-region <path>

Used in place of -kind to specify a region of design space in which to look for signals to log. Optional.

-recursive

Specifies that the scope of the search is to descend recursively into subregions. Optional. If omitted, the search is limited to the selected region.

-only

Can be used with a wildcard to specify that only virtual signals (as opposed to all signals) found by the wildcard should be logged. Optional.

-in

Specifies that the kernal log data for ports of mode IN whose names match the specification. Optional.

-out

Specifies that the kernal log data for ports of mode OUT whose names match the specification. Optional.

-inout

Specifies that the kernal log data for ports of mode INOUT whose names match the specification. Optional.

-internal

Specifies that the kernal log data for internal items whose names match the specification. Optional.

-ports

Specifies that the kernal log data for all ports. Optional.

<signalName>|<pattern>

Indicates which signal names or wildcard patterns should be used in finding the signals to log. Required. Any number of names or wildcard patterns may be used.
