Disconnecting Symbols from Nets in Schematics

Former Member
Former Member over 14 years ago

I often am in the situation where I want to shuffle the nets that connect two parts around to ease routing.  In the past, for large shuffles, I use cut, delete, paste.  I paste the part out of the way.  Shuffle the nets and the replace the part on top to remake the connections. This does keep all of the attributes, etc. however the layout tool treats the part as a brand new part which then needs to be placed again.  For signal net moves, I just copy the net and then delete the old one.

 

We are shuffling a couple of dozen signals on both a micro and a connector.  I must have placed the same parts 50 times in the last week.  This is driving me mad.  Any help would be appreciated.

 

Thank you in advance,

 

Jason

    how about making each connector pin a "gate" and then gateswapping them.

    or....just pinswap them, either way will somewhat scramble your

    schematic I think.

    While an interesting idea particularly for a connector, I can't possibly imagine doing that with a device like an micro or and FPGA.

    well, you could make, for example, all the digitals IOs swappable on the

    micro if they are arbitrarily assigned. or keep them in the same pins on

    the micro and just swap them at the connector if that would work for you.

     

    iirc, when you make the part, once you set the swap level up from zero,

    all the pins added will have that level, so as you make the part, you

    can build in swappability. but you have to anticipate that.
