Design.updateDesignWithCheckpointPlaceAndRoute does not seem to work for DCPs created with Vivado 2022.2

[jakobwenzel]

Design.updateDesignWithCheckpointPlaceAndRoute is supposed to behave identically to Design.readCheckpoint, only with a user-supplied pre-parsed netlist.

For DCPs created with Vivado 2022.2, this is not the case. In a Design loaded with Design.updateDesignWithCheckpointPlaceAndRoute, the list of SiteInsts is always empty. (Probably more field are not loaded correctly. I did not investigate further)

Code to reproduce (collapsed)

The main function takes DCP and matching EDIF as arguments.

public class CheckSiteInsts {

    private static List<String> getSiteInstsString(Design d) {
        return d.getSiteInsts().stream().map(SiteInst::getSite).map(Object::toString).collect(Collectors.toList());
    }
    public static void main(String[] args) {
        Design a = Design.readCheckpoint(args[0], args[1]);

        Design b = new Design(EDIFTools.readEdifFile(args[1]));
        b.updateDesignWithCheckpointPlaceAndRoute(args[0]);


        List<String> aSiteInsts = getSiteInstsString(a);
        List<String> bSiteInsts = getSiteInstsString(b);

        if (aSiteInsts.equals(bSiteInsts)) {
            System.out.println("ok");
        } else {
            System.out.println("fail");
        }

    }
}

Prints ok on expected list of SiteInsts, fail otherwise.
