In addition, all registers and register fields are available as variables, see Tcl API more information.
The info sys command displays how many ports are implemented in the router.

6.20. SVGA frame buffer
The SVGACTRL debug driver implements functions to report the available video clocks in the SVGA frame
buffer, and to display screen patters for testing. The info sys command will display the available video clocks.

The SVGACTRL core is accessed using the command svga, see command description in Appendix B, Command
syntax for more information.
The svga draw test_screen command will show a simple grid in the resolution specified via the format selection.
The color depth can be either 16 or 32 bits.
The svga draw
file
command will determine the resolution of the specified picture and select an appropriate
format (resolution and refresh rate) based on the video clocks available to the core. The required file format is
ASCII PPM which must have a suitable amount of pixels. For instance, to draw a screen with resolution 640x480,
a PPM file which is 640 pixels wide and 480 pixels high must be used. ASCII PPM files can be created with, for
instance, the GNU Image Manipulation Program (The GIMP).
The svga custom
period horizontal-active-video horizontal-front-porch horizon-
tal-sync horizontal-back-porch vertical-active-video vertical-front-porch
vertical-sync vertical-back-porch
command can be used to specify a custom format. The custom
format will have precedence when using the svga draw command.
