Hi,
I'm writing a script to prove top level requirements are covered.
I've got a recursive function like this:

def dfs(element, association, attribute, visited, fulfilled):
    """
    For the given element follow an association through the model
   When we get to a leaf, store the attribute
    """
    
    if element:
        
8000
children = eval(f"element.{association}")
        if len(children) != 0:
            for child in children:
                visited,_ = dfs(child, association, attribute , visited, fulfilled)
                visited.append(child)
        else: # no more associations, run the check
            # eg. get the satifisfiedBy block
            attr = eval(f"list(element.{attribute})")
            fulfilled.append({'element':element, attribute:attr})
    return visited, fulfilled

And used like this...

association = 'derived' # which association to follow through the model
attribute = 'satisfiedBy' # what relationship to check when we get to a leaf.
root = # Get your element somehow, I use a parser object for this Parser.block_objs[0] 

visited,satisfied = dfs(root, association,attribute,[],[])

# Take a look at the tree
for v in visited:
    print(v.name)
    
ok = True #Assume requirement is covered unless we find unsatisfied requirement in the tree
for s in satisfied:
    tmp = [x.name for x in s[attribute]]
    print(f"{s['element'].externalId} -- {tmp}")
    ok = ok and bool(len(tmp))

print(f"The requirement {root.externalId} is {True if ok else False}")

Hopefully other folks find this useful.
Should work for things like 'verifiedBy' too.
