Illegal charecter ' ! ' in netname.

Prasanna
Hi All,

We have a schematic in which some of the net names are started using ! symbol.  Ex:  !data_line0  etc.

There is no DRC error in the schematic. But when I tried to create netlist for Orcad PCB editor 16.2( allegro netlist) its giving error saying that " net name is having illegal charecter !"

Ex:  #2 Error [ALG0052] Net "!TRST" has illegal character "!".Please rename the net.

Is there any setting to allow these kinds of symbols instead of changing net name over whole big schematic.?

Is this charecter is not allowed in netlister?

Thanks,

Prasanna hegde

    Do you absolutely NEED to come out in Allegro PST netlist format? You could come out of OrCAD in another format (e.g. the non-PST Allegro netlist), edit the netlist to remove/replace the "!"and then import to Allegro.

    Not a preferred route, but something I have to do all the time when people send me netlists with illegal characters. Might be an option if your schematic is big and you are not exporting constraints data from the schematic...
