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.
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.
