Yes, this is a good idea. These attributes also show up using the report_property [get_nodes <node>]
Tcl command with attributes IS_GND
and IS_VCC
. I'm working on the 2019.1.0 RapidWright release now and I will update the device database files to include this information.
I see that Node.isTiedToGnd()
and Node.isTiedToVcc()
functions have been added in 2019.1 and are working for me. Thanks!
If you click on a VCC or GND node in Vivado, a "Tied value" item appears in the property pane thus:![Screenshot from 2019-05-29 16-35-27](https://user-images.githubusercontent.com/5521177/58570422-e0e9c000-822f-11e9-8494-f60c299f001b.png)
Would it be possible to add a function in RapidWright to get this (if there isn't one already that I've missed?) For now it seems like looking for "VCC_WIRE" or "GND_WIRE" in the node name should work, but this doesn't feel like the cleanest solution.
