This finds all the cells of a certain type but it doesn’t check if the CE is connected to VCC

show_objects -name find_1 [get_cells -hierarchical -filter { PRIMITIVE_TYPE == REGISTER.SDR.FDCE } ]

This however is more through: finds all flops with an enable pin and then verifies that it’s not connected to power (vcc)
set ffs_with_ce {}

foreach ff [get_cells -hier -filter {PRIMITIVE_SUBGROUP == “flop”}] {
if {[get_property TYPE [get_nets -of_objects [get_pins -of_objects $ff -filter IS_ENABLE]]] != “POWER”} {lappend ffs_with_ce $ff}
