Need help with TCL code to modify offpage

gvellet

Hi,

Sorry I have to ask another question about TCL scripts to fix problem with schematic imported from Mentor PADS.

This time the problem is with the imported offpage symbols. The "Name" property value is wrong; it is always "PIN0" instead of the associated net Alias, and also the property value is hidden (impossible to make it visible through orcad GUI interface). As ripple effect, the offpage Name values override the net Alias resulting that all nets with offpage symbols  are shorted to this dummy "PIN0" net.

I made a TCL script to edit all the offpage symbols, it modifies the Name property value to match the net Alias and to make the value visible. The script works but there is a big problem, the netname do not follow, they either stays stuck to "PIN0" or more strange they are reassigned to random valid netname. The script modifies the offpage instances and I wonder if it is a problem where occurrences should be modified instead of instances. I tried a little to change my script for occurrences but I run into problems that the object method I need not working or I do not know which method I should use.

I also wonder if the problem is more like I must trigger something in Orcad to tell it to copy offpage name into the wire netname?

Please I need some expert help. I have attached a zip including the tcl script and an anonymized schematic with the buggy offpage.

Best regards,

     I spent so  many hours trying to fix my script. Then you add a single line of code and it fixes completely the problem, simply Amazing!

    I have a question about the command "DboTclHelper_sEvalPage". Do you recommend adding it to any script which is modifying a schematic page per page using "set lPage [$lPagesIter NextPage $lStatus]" ?

    Best regards,

    Yes, after modification of schematic page you can add command "DboTclHelper_sEvalPage".
