Help on getting net names and Instance names on a path untill sequential(DFF) circuit is found.

venuuuuu

 Hi all,

        I am trying to write a script for getting instance names and net names on path in digital circuit untill sequential circuit (like DFF) found in schematic. I want to check it hierarchy level also.  For example when I select some net in schematic thenSome file will show: "EN", "AND" , "net2", "OR", "net3","NOT" ,"net3" (net 3 will connect to as D in DFF).

  • Hi Venu,

    I think that Solution 11476064 may help you with this - basically from a net dbId you can get the instance terminals (instTerms) that are on the net, from this you can get to the instance dbId (inst) which will give you the instance name / cell name (name / cellName). For following the hierarchy you would need to open the appropriate schematic view - you may need a switch view list for this or perhaps you wish to follow a configuration (as built by the Hierarchy Editor) - the latter is slightly more complex, but I know that code has been written for that case also.  There may be other solutions in COS (Cadence Online Support), did you search?  If so, what terms did you put?  For my search I used "skill net hierarchy" and the solution was on the expanded first page (i.e. not amongst the first 4-5 results, but in the first 10).

    Hope this helps!

    Regards,

    Lawrence.
