The state of the generation of symbols

Hello folks,

especially Mentor folks

 

I was today stuck with the difference that I see in generating a symbol using DxD and the integrated bottom-up and top-down methodologies.

 

Imagine you have a complex circuit here simplified as resistors

Now imagine that I would like to substitute the second resistor (representing a part of the circuit) with a block.

There are two ways for doing this.

 

  • The top - down aproach

 

In DxD I use the add--> block command

and I get a generated symbol that looks like this.

It has a double border and it gets a name that was given in the requester.

 

  • The bottom-up approach

 

Here I start with the lower level and put ports

and let the tool generate a symbol with the tools--> Generate block symbol.

 

The wizard will open a new symbol in symbol editor that looks like this.

This block has a simple box and I can shape it as I like.

 

 

Summary:

The tool is presented with the possibility to do both approaches, but the difference is striking.

In a schematic this looks very confusing and misleading. In this example like this:

 

 

My question are.

  • Does the tool have a "standard" way to represent block symbols (Is it always double lines, or always simple lines, or something else)
  • Do I have to correct all the block symbols by hand to match the other style?
  • Is Mentor aware of this discrepancy
  • Does Mentor plan to do something in this area?
  • Has anyone come up with a better solution to this?

 

Thanks for every insight.
