PhysicalNetlistToDcp converting .phys(only placements) to DCP

[zhilix]

I tried to use PhysicalNetlistToDcp to convert my placments in IF to DCP, and I commented off the xdc input requirement.

It seems that Rapidwright can't read physical netlist that only has placments field.

Here are the .netlist and .phys files that I used: netlist_phys.zip .

I was able to reproduce the issue. Please try again with #495, however, I think there is information still missing that is not being populated. I have changed RapidWright to be more forgiving, however, the file is missing the SiteInst information, those fields are empty.

Also, when I attempted to load the design into Vivado, it crashed, so there is something else that is missing. Unfortunately, I don't know what that might be but if you could start with an equivalent file in Vivado of what you think you should expect, then convert that back to Interchange, that should give you a hint of information you might be missing.

Thanks a lot, I think I'll start adding other fields as well, it seems other fields are also necessary for Vivado to load the design successfully.

Did #495 fix this? If so, we can close.

[zhilix]

Yes, this is fixed, please close it.
