how to check floating cell and pin in prime time?

[xchuang]

i am a new timing analizer, when runing sta in prime time , i want to find the floating point using tcl script, i think that get all nets ,then get all the pins(ports)
connected to every net, if there are input and output pins(ports), so this net is not floating,
++++++++++++++++++++++++
set all_nets [get_nets * -hierarchical]
foreach_in_collection net $all_nets {
set all_pins_or-ports [all_connented $nets -leaf]
foreach_in_collention pins_or_port $all_pins_or-ports {
now ,i don't know how to find

+++++++++++++++++++++++++++
i need help,tks.

set all_nets [get_nets * -hierarchical]
foreach_in_collection net $all_nets {
set ctr [size_of_collection [get_pins -of $net -all]]
set net_name [get_attr $net full_name]
if { $ctr } {
puts "$net_name is not a floating net"
} else {
puts "$net_name is a floating net"
}
}

This code gives the floating nets in the design. Basically your question is not clear based on your discussion you had provided in the post. Let me know if you are looking for something else.

plz check the circuit, pin Z of AND gate is connected to net n3, but n3 is not connected to any input pin or output port, so the AND cell has a floating pin, it is a floating cell
