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).

  •  I wrote below code which is not working properly. Actually I planned for top level check only.The hilighted code is for finding output net name of a device because I dont know simple command for getting it. I have problem with order of output nets and devices. And I need hierarchy level also. 


    instancesfornet=nil
    outnets=nil
    outnet=nil
    procedure(FPSfindpaths(@optional 
        instid outnet
        (visited makeTable('visited nil)) )
    if(outnet==nil
    outnet=car(geGetSelSet())~>net~>name
    )
    mynet = dbFindNetByName(geGetEditCellView() outnet)

       sig =car(mynet~>signals)

    foreach(mInstTrm sig~>memInstTerms
    instancesfornet=cons(car(mInstTrm)~>inst instancesfornet)
       )
    foreach(instid instancesfornet
    unless(visited[instid]
    visited[instid]=t
    i=0
    directions=instid~>instTerms~>direction
    nets=instid~>instTerms~>net~>name
    foreach(output directions
    i++
    v=strcmp(output "output")
    if(v==0 then
    i1=i
    )

    )
    i=1
    foreach(net nets
    if(i1==i then 
    outnet=net
    outnets=append(list(outnet instid~>cellName) outnets)
    )
    i++
    )


         outnet=FPSfindpaths(instid outnet visited)
        )
      )

    foreach(name1 outnets
    printf("   %s " name1))
    outnets=nil
     outnet=nil
    instancesfornet=nil
    )
