    CDLin pin/net mismatch Reply


    I am having a CDL netlist with information:

    *.GLOBAL VDD:p, GND:g
    *.PIN VDD:B, GND:B

    and when I CDLin, both symbol and schematic views have pin/signal names as VDD!/GND! instead of VDD/GND.

    I do not want VDD/GND suffixed with ! in my cell views. Is there a way to achieve this?

    Thanks in advance...

    Remove the *.GLOBAL from your netlist.

    This is stating that those names are global, and in order to meet the Virtuoso Schematic Editor's conventions for global names, it has to add a "!". Whilst the database itself can cope with globals without "!", if a schematic was created which had global nets in it without the "!" suffix, doing a check-and-save would convert them back to not being global. So it's important that CDLin translates any global names in the CDL namespace to be an equivalent global name in Virtuoso's namespace.
