Regarding Reference Designator / reuse / renumber /...

archive

My quesiton is the following, and is looking for any comments and experience.

I am converting from Orcad( Design Entry CIS) to Concept( Design Entry HDL) for schematics entry. From Orcad, I am able to renumber the whole schematic, or set all reference designator to ?, so that I can update the entir design.

Now, in DE HDL, I see that reference designator started to be ?, and after I "export physical", I can then see the updated refdes like R1, R2..etc.

How do I setup so that I can see all the reference designator converted to ? such as R?, U?, D?..etc.

Also, I am looking for refdes reuse setup. For example, I have deleted R5 and R7, how to I make the later added refdes does not use R5 and R7, but continue from the largest value. Or, vise versa.

Any ideas?
Your helps are much appreciated.

    Hi Jason

    There's 2 levels of property in DEHDL - soft and hard. Soft properties are typically system assigned (like by the packager when Export Physical is run), and these soft properties do not need to be set (can have a value of ?). Hard properties are set by the user and need to have a value (other than ?) otherwise an error is generated on Save in DEHDL.

    The LOCATION property is a hard property, the equivalent soft property is $LOCATION - so in the sch everything that has a LOCATION property needs to have a value set to save without an error.

    It sounds like your schematic used hard LOCATIONS - which leaves you with 2 options:-

    1. Manually set all the LOCATION properties
    2. Change the LOCATION property to $LOCATION (using Global Update)

    The second is the easiest - once this is done the sch should save and export physical OK (as long as there are no other errors), and the $LOCATION property will be populated by backannotation.

    Cheers
