how to report floating terms of a cell

Hi Abhishek, Thanks for posting this question to the forum. The "checkNetlist" command reports the number of floating output terminals, but it doesn't tell you which ones they are unfortunately. There's room for enhancement there for sure, and I'd encourage you to file a request through the Cadence support channels you interact with. As a workaround, or in general when you have focused characteristics you'd like to search for in your design, you can use db access commands in Encounter. There are 2 styles of db access commands: "FE-TCL" and "dbGet". dbGet debuted in 7.1 and provides a more intuitive relational representation of the db. FE-TCL is the long standing db access mechanism in Encounter. I've included sample solutions for your query in both styles below for your reference: Puts "dbGet example:" foreach outputTerm [dbGet -p top.insts.instTerms.isOutput 1] { set net [dbGet $outputTerm.net] if {$net > 0} { if {[dbGet $net.numInputTerms] == 0} { Puts "[dbGet $outputTerm.name] connects to net [dbGet $net.name] which is floating" } } else { Puts "[dbGet $outputTerm.name] is floating" } } Puts "FE-TCL example:" dbForEachCellInst [dbHeadTopCell] inst { dbForEachInstTerm $inst term { if {[dbIsTermOutput $term]} { set net [dbTermNet $term] if {$net > 0} { if {[dbNetNrFanOut $net] == 0} { Puts "[dbInstName [dbTermInst $term]]/[dbTermName $term] connects to net [dbNetName $net] which is floating" } } else { Puts "[dbInstName [dbTermInst $term]]/[dbTermName $term] is floating" } } } } Please do post back if you have further questions.
