save_image with heatmap on layout

[gudeh]

Hi!

I would like to call the TCL command save_image and include the heatmap values on the layout.

I noticed that by manually clicking on the visibility of a heatmap (such as "Placement Density") the image provided by save_image will include the heatmap.

My question is how to do this programmatically? I have a TCL script where I save the data with gui::dump_heatmap and I would like to also save the image with heat values afterwards. How can I toggle the visibility of heatmaps with my TCL script?

See gui::set_display_controls in https://github.com/The-OpenROAD-Project/OpenROAD/tree/master/src/gui

Our nightly CI uses https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts/blob/master/flow/scripts/save_images.tcl which is a good reference.

Nice! I noticed the gui::set_display_controls, but couldn't find the name of the control.

This seemed to do the trick:
gui::set_display_controls "Heat Maps/Placement Density" visible true

The link you provided has another example, also.

The names match what you see in the 'Display Control' panel:
