During the DRC the query 404 is per default set to check wether the pin property # is defined for blocks.
What is this used for ?
This setting is incorrect and really doesn't make any sense as you stated in one of your responses (and to answer aclark, no it wasn't added for a reason, simply a mistake). If you have properties that you need to check for on block symbols then add them to the checks but I'd suggest you remove the Pin Number property from this check.
If this is answered to your satisfaction please mark it Answered.
In Dxdesigner Netlist Flow (the version which comes with Pads), the property "#" means Pin Number.
Yes, that's fine, and also reasonable for symbols which have a layout counterpart (where the pin numbers are necessary).
The DRC-404 checks whether the pins of blocks have a number. What is it used for ?
SB did you get an answer to your question in the end?
I am just doing my first serious board using DXD-Exp and want to make sure that everything is OK. Mentor must have included this check for a reason, and I don't want to have to compile a >12,000 net netlist containing >3,000 components and manually compare it with the PCB layout!
It doesn't look like this check has the correct configuration, there does not appear to be a reason to check for Pin Number (#) in this instance. However we will do some investigation to determine why this setting has been defined the way it has. I would suggest that for your purposes you ignore this check.
